Symptom



1.     You can browse the RWW website but when you try to use the connect to a computer feature you may receive the following error message. 

 

---------------------------

VBScript: Remote Desktop Disconnected

---------------------------

The Terminal Services Gateway Service service is not running. Contact your network administrator to resolve this issue.

---------------------------

---------------------------

 

 

2.     If you try to connect to the server using TS Gateway through an remote desktop client, you get the following error:

 

[Window Title]

Remote Desktop Disconnected

 

[Content]

This computer can't connect to the remote computer because the Terminal Services Gateway server is temporarily unavailable. Try reconnecting later or contact your network administrator for assistance.

 

[OK] [Help]

 

Cause



These are some of the common causes of this error:

 

1.     SBS Web Applications is missing binding for port 443 or multiple websites have this binding and one of them is only started because of that -- This might happen if someone has tried binding port 443 to another website.

 

2.     We might find port 443 binding present with Default Website -- This will happen if we have manually chosen the option to configure IIS for TS Gateway in TS Gateway manager

 

3.     HKLM\Software\Microsoft\Rpc\RpcProxy\ is missing Website key which represents the value for the website where rpc and rpcwithcert directories are.

 

Resolution



1. Run Fix my Network Wizard (this step should fix everything except creating registry entry if that is missing)

 

i) Manually remove 443 binding for Default website -- 443 binding is assigned to Default Website when you click "Configure IIS Settings for TS Gateway" in the TS Gateway console.

 

ii) Make sure we have 443 binding present with proper certificate

 

 iii) Manually create the registry key HKLM\Software\Microsoft\Rpc\RpcProxy\Website with the value "SBS Web Applications"
