Good Evening,
Wanted to let it be known a fix for the dreaded "Desktop has failed open" error. The key is to remove a registry key. Here are the instructions:
1. Start Registry Editor.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TermService\Parameters
3. Under this registry subkey, delete the following values:
Certificate
X509 Certificate
X509 Certificate ID
4. Quit Registry Editor, and then restart the server.
In most Windows XP systems, the Certificate key is present. If you remove it, the error should disappear. However in Windows XP, Windows XP will regenerate a new key. Therefore the value at that key is what seems to be the cause or possibly one of many causes for this error.
