We have 4 user accounts setup for RDP access to our server. They have been working just fine, and all 4 continue to work just fine from any workstation except for one.
On that workstation, only 1 or 2 of the rdp accounts are able to connect. The other accounts respond with an error message talking about incorrect credentials. However, when we test those credentials from another workstation, the RDP session connects with no problem.
The exact accounts that work or are refused on that workstation vary from day to day it seems.
This is driving me nuts!
Is there some kind of cache that needs to be cleared out that is broken or something?
