I set up a few administrative terminal servers (W2K8 R2) and installed SQL 2014 SP1 Management Studio to manage remote SQL servers. On one of these servers I suddenly had a problem when connecting to SQL servers:
- When using windows authentication, SSMS won't connect to the remote SQL server, the window (Connect to server) stays grayed out - only the Cancel button remains active. After 5-10 minutes it either connects to the remote SQL server or gives up with no message, all window elements go back to being active again
- When using windows authentication with an account which is not authorized it immediately brings up the error message that the login failed.
- When using SQL server authentication it won't connect with greyed out window (authorized account or not).
- Looking at network connections you can't see any activity from ssms.exe process when the problem occurs.
- Reinstalled management studio with no effect.
I ended up reinstalling the whole server to get it working again. Unfortunately now an other server has the same problem. Any hints what might be the culprit?
