ActiveSync, OWA, EMC and IIS stopped working in Exchange Server 2010

When ActiveSync in Exchange Server 2010 becomes inoperable due to unknown reason, other applications that are linked up with Active Sync may become non-functional as well. In my case, I have stumbled upon where smart devices stopped synchronizing to Exchange Server 2010, Outlook Web App (OWA), Exchange Management Console (EMC) and Internet Information Services (IIS) also became inoperable.  Note that Microsoft Outlook is fully operational.

Resolution:

  • Navigate to C:\Windows\System32\inetsrv\config, locate applicationHost.config and rename to applicationHost.config.old

applicationhost location

 

  • Replace the file C:\Windows\System32\Inetsrv\Config\Applicationhost.config from a backup.
  • Open a command prompt and run iisreset to Reset the IIS Service.

iisreset command

Now, test the email flow from a smartphone. Access the OWA, open up EMC and IIS. They should all start working and be fully functional.

How to Find and Install an Emulator Printer Driver to Work in Your Network

In this Tutorial you will learn how to use a Windows native 32-bit printer driver so that you may use a printer in your network that’s connected to a computer running a 64-bit Windows Operating System.

Are you having a hard time finding the correct printer driver? This has always been an issue, from my own experience. I have also struggled looking for printer drivers that would work and able to utilize the Windows native printer driver and I have succeeded when experimenting on finding the correct printer driver, this is also known as driver emulator.

The Process: We will be experimenting an Okidata 420 Microline (OKI 420 ML) impact or dot matrix printer that is connected thru a USB cable into a Windows 7 Professional 64-bit computer and it is shared on the network. Begin with the ‘Welcome to the Add Printer Wizard’ from a Windows XP computer and locate a compatible driver to emulate the OKI 420 ML using the XP native printer driver.

To begin: You will need to be an Administrator or a Member of Administrator Group. From a Windows XP computer, click on Start then Printers and Faxes then click on Add Printer to start the Welcome to the Add Printer Wizard, click on Next to continue.

In the Local or Network Printer page, choose ‘Local printer attached to this computer’, uncheck the box next to ‘A network printer, or a printer attached to the other computer’, click on Next to continue.

In the ‘Select a Printer Port’ page, choose Create a new port: type of port is Local Port.  In the Enter a Port Name dialog box, type the path of the printer by using the following syntax:  \\ComputerName\printer name then click on Next to continue.

Note: the ComputerName is also known as the ServerName

You will now see the Local Port that you have created, click on Next to continue.

In the Install Printer Software page, select the printer driver that you are going to use, in this Tutorial we will select the Oki ML 321 Elite (IBM) because this driver is compatible with  OKI 420 ML printer, click on Next to continue.

In the Use Existing Driver page, select Keep existing driver (recommended), click on Next to continue.

In the Name Your Printer page, type a printer name that you wish, click Next, then Next again to continue.

In the Completing the Add Printer Wizard page click on Finish.

You have successfully completed adding a Local printer port and utilized a windows native printer driver (emulator) called OKI 321 Elite(IBM) that’s compatible with an OKI 420 ML printer . You may use this procedure to any Deskjet or Laserjet Printers, feel free to do a little research and then experiment what other Windows native printer driver that you may use, this will save you plenty of time to browse online and search for the printer drivers.

How to Setup Workgroup for Home, Home Office and Small Business

This Tutorial is intended for a Workgroup and not for a Domain type of network. Also, if you have both wired and wireless devices that need to communicate in one internal network you may use this tutorial to share network resources such as integrated and external drives, folders, files and wired/wireless printers. In this guide, we will be utilizing the Business and not Home Versions of Windows Operating Systems. If you have a combination of Home and Business versions of Windows Operating Systems, this guide will also work but with slight discrepancies on some configurations. You must have Administrative privileges to complete this process. A Server won’t be necessary in this Tutorial.

For a better network performance and to avoid network bottlenecks, using advanced technology would help. For example, instead of using a B/G router, an N Router will perform better. A router with 1000Mbps or Gigabit ports and Network Adapters that supports 100/1000Mbps is also doable for faster network transfer rates. Gigabit Network Switches would be beneficial.

Pre-requisites: Computers with Network Adapters for LAN and WLAN, Network Switch (for additional wired devices), Wireless Router (verify that DHCP is enabled), a working Broadband connection, a couple of straight network cables (Cat5e or higher) other wired and wireless devices such as Printer, NAS etc.

Connect all the computers and wired devices to the Router’s LAN or Ethernet Ports (usually 4), you may add a Network Switch (to be plugged into the LAN or Ethernet Port of the router) if you will be connecting more wired devices such as Printer and NAS. The wireless computers and devices will need wireless network adapters also known as Wi-Fi adapters. Make sure that the wired and wireless devices are able to communicate to the router and access the internet.

1.      Enable DHCP in the LAN (Local Area Network) or WLAN (Wireless Local Area Network) settings on all the computers in your network.

In Windows 7 and Vista – Click on the Start button, type ncpa.cpl then press enter to open up the Local Area or Wireless Connection Status screen. Double click on Local Area or Wireless Connection, then click on Properties, double click Internet Protocol Version 4 (TCP/IP v4), make sure that Obtain an IP address automatically and Obtain DNS server automatically are both enabled.

In Windows XP – Click on Start, type ncpa.cpl to open up the Local Area or Wireless Connection screen.

Double click on Local Area or Wireless Connection, then click on Properties, double click on Internet Protocol Version 4 (TCP/IP v4), make sure that Obtain an IP address automatically and Obtain DNS server automatically are both enabled.


2.    Enable Netbios or verify that Netbios is enabled.While you’re in the LAN or WLAN settings, to check if Netbios is enabled…. In the General Tab, click on the Advanced button. In the Netbios setting, make sure that the radio button is On under the Default.

3.  Create a Workgroup:

In Windows Vista and 7 – Click on the Start button then go to Control Panel, click on System and Security, click on System then click on Change Settings then type the Computer Name (must be unique) and your Workgroup (must be identical on all computers).

In Windows XP – Click on Start, right click on My Computer, then Properties, in the Computer Name Tab then type the Computer Name (must be unique) and your Workgroup (must be the identical on all the computers).


4.      Create an Identical User Name and Password:

In Windows 7 and Vista – Click on the Start button, then go to Control Panel, click on User Accounts and Family Safety, click on User Accounts, click on Manage User Accounts.

In Windows XP – Click on Start, then go to Control Panel, go to User Accounts, and click on Create a New Account.

5.      Allow File and Printer Sharing in Windows Firewall:

In Windows 7 and Vista – Click on the Start button, then go to Control Panel, click on System and Security, click on Windows Firewall, in Allowed Programs make sure that File and Printer sharing box is checked.

In Windows XP – Click on the Start, go to Control Panel (Category View), go to Security Center, find Windows Firewall, then in Exceptions Tab, make sure that File and Printer sharing box is checked.

In the next guide we will share a Folder or a Drive (C, D). I have created a Folder called ‘My shared folder’. Right click on it, choose Properties, in the Sharing Tab click on Share.

Add the User(s) that need to access the shared Folder and assign User permission in the Sharing Tab.

Click on Share….

In the Security Tab, verify that the same User has been automatically added.


In Windows XP Professional, it is a slightly different process. Right click on the Shared folder. Go to Properties, on the Sharing Tab, click on Permissions button, verify that Everyone is there, if not manually add Everyone and leave the default to ‘Read’ permission for now. Add the Users and assign them Read or Read/Write permissions if applicable. Click Ok to save the setting.

In the Security Tab, click on the Add button and add the Users, then assign them permission as well.


6.      How to connect to the Shared Folder or Drive:

From the computer that you would like to access the shared folder thru its IP Address or Computer Name…..

Click on the Start Orb and type \\IPAddress\SharedFolder  or Shared Drive then press enter, for example: \\192.168.0.3\C (shared drive)

or….Click on the Start Orb and type \\Computername\SharedFolder or Shared Drive then press enter.

7.       How to Share a Printer (thru a USB or LPT port connected to a computer):

In Windows 7 and Vista – Click on Start, go to Control Panel, go to Hardware and Sound, go to Devices and Printers. Right click on the printer that you need to share, choose Printer Properties, in Sharing Tab make sure that ‘Share this Printer’ and ‘List in the Directory’ boxes are checked.

8.     How to connect to a Shared Printer:

In Windows 7 and Vista – Go to Control Panel, go to Devices and Printers, go to Add a Printer, click on Add a Network,  click on Add a Network, Wireless or Bluetooth Printer.

My preferred method….Click on the Start button and type \\IPAddress (Computer’s IP Address you are trying to connect to) press enter or type the \\ComputerName then press enter. 

You will now see the name of the printer shared from the network, double click on it to install to your computer.

In Windows XP – Go to Control Panel (Category View), Printers and Other Hardware, Add a Printer, Welcome to the Add Printer Wizard, click next, click on A Network Printer, or a printer attached to another computer.

My preferred method….Click on Start, in the Run box type \\IPAddress (Computer’s IP Address you are trying to connect to) press enter or type the \\ComputerName then press enter.

Note: See this ipconfig /all Tutorial on how to find out the IP Address of a computer.

You may also use Advanced IPScanner to find all IP Addresses, Mac and Host Name in your network.

Optional:

If you have a network printer that can be wired to the router thru a patch network cable (Cat5e or higher) plug it in to the router’s LAN or Ethernet port.

If you want to connect a Wireless printer to your wireless network, make sure to have the SSID and passphrase ready. In order to setup a wired (thru a USB or Ethernet cable) or wireless network printer, you will need the installation CD that came with your printer, then install it on all of your computers and follow the Setup Wizard.

If you have a NAS, unpack your NAS device from its package; it should come with a patch network cable and an installation CD.  Plug the power cable to the NAS, connect the network cable from the NAS to the router’s LAN port or to a network Switch, turn on the NAS, and wait for the light to stabilize. Insert the CD to any computers in your network then follow the straight forward installation. Make a note of the IP Address that will be assigned to your NAS, you will need this later on to access the NAS’s configuration. Create file folder(s), assign Users with permission as needed and you will be all set.

If your router has a USB Port, you may utilize it and share a USB external hard drive for backup purpose and printer in your network. You will access them thru the Router’s IP Address and the network resource name.

You may also share the Media by using your Smart Phones such as IPhone and Android. All you need is to download the Apps for Media Sharing. Android phones by default comes with a ‘Media Share’ App.

Troubleshooting tips:

Just in case that you can’t access the shared driver or folder – check your Firewall or Security Software and make sure that File and Printer Sharing is set to Allowed. If you can’t access any network resources, you may temporarily disable your Security or Firewall Software. To do this, click on the Start Orb and type services.msc press enter, locate your Security or Firewall Software and choose Disable or Stop for now until you’re able to access the network files/printer.

To find out if the computers are communicating to each other try pinging the IP Address of the computer that you wish to gain access to its network resources. To do this, click on the Start Orb and type cmd press enter. From the command prompt type the IP Address of the computer that you need to access or connect to, for example type ping 192.168.0.3 press enter. If you get a ‘Request timed out’ then your computer is unable to communicate to the other computer in your network. Sometimes, a comprehensive network troubleshooting might be needed if it gets a little complicated to resolve any network issues.

How to uninstall a Network Adapter (or any Device)?
In this Tutorial, we will use a Network Adapter as an example.
Locate and expand Network Adapters, right click on the Network Adapter (Intel) that needs to be uninstalled, choose Uninstall.
 
To reinstall the Network Adapter’s driver, without updating it, simply restart your computer and your Windows should automatically detect and install the Network Adapter.

To manually install a Network Adapter’s driver because Windows didn’t automatically detect the driver or if you have downloaded a new driver, after you have uninstalled the driver please do not restart your computer. Instead, from the top Menu choose Action then Scan for hardware changes.

How to update your Network Adapter’s driver?
Right click on the driver and choose Update Driver….
 
From the Welcome to the Hardware Update Wizard, choose the first option, ‘Yes this time only’, click on Next to continue.
 
Click next; I prefer the second option ‘Install from a list or specific location (Advanced), click on Next to continue.
 
Locate the Driver for your Network Adapter and click ok to select it.
 
Note: Most of the Device drivers that you would have to download from the Manufacturer’s site are compressed files. Therefore, you will need to unzip the folder then manually select the .sys file (for ex. Atheros) -this is the working Network Adapter driver. For other Drivers it might be different. Also, some of device drivers comes with executable file, so the previous process won’t be necessary.
How to Disable a Network Adapter from Device Manager?
Locate the Network Adapter that you wish to disable, right click on it and choose Disable.
Note: You may temporary disable any Device Drivers for troubleshooting purpose only. You may enable it back by repeating the same process but choose Enable this time.

How to Setup a Wireless Network

Pre-requisites: You will need a working Broadband Connection; Wireless Router;  Computers with Wireless Network Adapters; and other wireless network devices such as Smart Phones, iPad, wireless printer, Gaming Console (eg…PS3, Xbox), Smart TV, Roku Box, etc.

In this Tutorial,  we will use a Linksys Router. The procedure may vary depending on the Model of your Linskys Router but it will be similar. Other routers such as D-Link, Belkin, Netgear, etc. will have similar features. Installation CD is not required in this process, this is a manual process.

List of Default Router’s IP and Admin Passwords:
http://www.answersthatwork.com/Download_Area/ATW_Library/Networking/Network__4-List_of_default_Router_Admin_Passwords_and_IP_addresses.pdf

Connect a patch network cable between the Modem output port and the Router’s WAN or Internet Port.  Connect a patch network cable (also called an Ethernet cable ) from one of the router’s LAN or Ethernet Ports to each device that will use a wired connection. Keep an eye on the Modem and Router’s lights until they are stabilized. You may need to do a Power Cycle just in case you can’t access the Router’s IP Address.
Note:  Crossover network cable is not required if your router supports Auto-negotiation.

While your computer is connected to the router, open up a browser (IE, Chrome, Firefox) and type http://192.168.1.1, this will prompt you for a User Name and Password, The default User Name (for most of the Linksys Routers) is admin, default Password is admin. It is advisable to change the User Name and Password for security purpose.

In the Basic Setup page, verify that DHCP is enabled and that there are at least 50 DHCP Users.

In the Administration Tab you may change the Router’s password (do not use the default password for security reason).

In the Wireless Tab, then Basic Wireless Settings, change the SSID or wireless network, make sure not use your Router’s Name.

In the Wireless Security Tab, you may setup your wireless network encryption.  It is recommended to use WPA2, then type in the Shared key (also known as security/ encryption key or pass-phrase) of your choice and make a note of it because you will apply the same Shared key on all your wireless devices that need to be connected to this router. If, for some reason that other wireless devices can’t connect to your router, you may change the wireless security in Security Mode, try not to use WEP because this is not secured at all.

I prefer to manually setup the Security Mode. Although, you may choose to use the Wi-Fi Protected Setup (WPS) to automatically set up your wireless security.

Other options that you may configure later on: Application Rules, Port-forwarding, Firewall Setting, Quality of Service (QoS) etc…..and all of these can be found in the Advanced Setting tab.

Now save all the settings.  In the WAN page of your router verify that you can see your ISP’s Public IP information and all of the settings that you have made. Once everything is verified, you have just completed configuring your router.

Your next task: Connecting all your wireless computers and devices to your wireless router. Ensure that you have the SSID and pass-phrase ready.

Log on to your Windows  7 and/or Vista wireless computers andclick on the network icon or  in the notification area. Choose your own SSID or wireless network name (SSID must be broadcasting)  that appears on the connections available.

Log on to your Windows XP wireless computers and connect to your SSID.  As you can see in this image the wireless network connection properties is different than Windows 7 and Vista.
 Click Connect to your SSID and it should prompt you for the Security key, make sure to correctly type it in. You should now see that your computer is connected to your wireless network.

Now that you have a wireless home network setup, it is recommended that all computers have Firewall enabled. The Windows built-in Firewall is a good protection. Anti-Virus and Anti-Spyware/Anti-Malware Software must be installed as well.

Also, if you’re having a minor networking issue such as disconnection after all of the above configurations, a Power Cycle might help. If, for some reason your wireless connection doesn’t work, depending on your ISP, you might need to enable Mac Cloning. This option is visible in your router setting.

Note: Don’t forget to connect the rest of your wireless devices such as Smart Phones (IPhone, Blackberry and Android) wireless NAS, wireless Printers and gaming consoles to your wireless network.
