Troubleshooting Connectivity Issues with Terminal Services January 23, 2011


One of Microsoft’s biggest support call generators has always been the dreaded ‘Remote Desktop Disconnected’ or ‘Can’t Connect to Remote Computer’ error messages when trying to connect to a terminal server from a client. The problem with this issue is that there are a myriad of causes that all end up causing the same symptom. Since there are several causes for the same thing, there is a lot of information out there on how to troubleshoot the various causes. The problem is, all of this troubleshooting material is spread out in multiple Knowledge Base articles and who knows where else on the internet, and even worse, there is no way to tell which cause may be the root of the problem in a given case. So, even if you query the internet and find articles that mention the error message, the articles you find may or may not even apply to your situation.

So, the point of this post is to simply point out the links to the three articles in question. If you are the administrator of any sort of terminal server environment, I recommend keeping these links in your favourites in case you need them in the future:
