Here is one of those cryptic error messages when connecting to an SBS server via RDP:
Remote Desktop Disconnected
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.
Now, since we are the network administrators, we now need to figure out just what is going on.
The first instinct is the Internet connection may be down. But, when we bring up the Remote Web Workplace (RWW), the site is there.
Try and log onto the RWW, and this is what we are greeted with:
RWW: Password change needed
If we did not try and log onto RWW, the next logical step would have been to troubleshoot what was going on with the TS Gateway service in the logs.
Once into the server, the TS custom view in the Event Viewer had no errors whatsoever.
In our custom logon failure Event Viewer Custom View (SBS CodePlex) however, we found the following:
An account failed to log on.
Security ID: NETWORK SERVICE
Account Name: SBS$
Account Domain: MySBSDomain
Logon ID: 0x3e4
Logon Type: 3
Account For Which Logon Failed:
Security ID: NULL SID
Account Name: MyUserName
Failure Reason: The specified account's password has expired.
Sub Status: 0xc0000071
A quick run through the logs produced the above. We made sure that all of the services were happy before accomplishing the folder recovery we needed to and then logged off.
