Now started installing the 1 of the old update first, Wow its done.

Spooler.Xml File - Huge Space

                       Spooler.Xml File - Huge Space in the directory %windir%\system32\spool folder.

you face this any time on Printer server, that Spooler.xml file is occupying huge space %windir%\system32\spool folder.

This is due to the Windows Error Reporting service for print spooler which has introduced from 2003 SP1. The majority of issues where seen in Windows 2008 server where print spooler is installed and if the Print Spooler  enters into a error state or crash or a busy condition the Windows Error Reporting starts writing the activity into Spooler.xml and keep on goes increasin its size. This log is like Extra level of logging for spooler.

This Windows Error Reporting  for spooler is enabled by Default, you can diable this feature by using the registry key.

• Click Start, click Run, type regedit, and then click OK.
• Expand the following subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print
• Create a new DWORD Value, and then type DisableWERLogging in the New Value field.
• Right-click the DisableWERLogging registry entry, and then click Modify.
• In the Value data box, type 1, and then click OK.

Once the registry changes are made, please restart the print spooler service.

Done now we have stopped the logging of Spooler.xml file, go a head and delete the file to get the free space back on the server.

2008 R2- Remote Desktop Web Access (RD Web Access) for External Users

           Remote Desktop Web Access (RD Web Access) for External Internet Users

Today i went through an issue where remote desktop services configured for web access. We have a valid certificate and every thing seems to be fine.

We are able to access the RD Web APP both internally and externally, I can initiate RDP to the computers Internally and when it comes to External i am unable to initiate RDP, error " could not connect to the computer".

I have investigated on this and noticed that for External access of remote servers using RD web app we need to have any of the below condition.

• VPN Access: If are having the customers VPN connected then we can access the computers using RD Web app. 
• RD gateway server: The second option which is the very important option for easy RD web accessing of computer. We need to install the RD gate way service to the Remote Desktop Services role and need to configure this.

Few things to do after installing RD gateway: 

1. At "test.testing.com", log in as Administrator.
2. Launch "Internet Information Services (IIS) Manager".
3. Expand "test> Sites > Default Web Site > RDWeb > Pages".
4. In the detail pane, double-click "Application Settings".
5. Double-click "DefaultTSGateway".
6. Under "Value", type "test.testing.com".
7. Click "OK".

What happens if RD gate way role is installed and configured properly.

1. The users who are coming to access the network resource  (Remote computers etc.) they will be authenticating to RD gateway and from there it will be routing to the selected computer and establishes a session.
   
   
   Issue is resolved we are able to access the network computers out side the internet using RD Web Access App successfully. :-)
