Suddenly in one of our test environments, K2.Net 2003 Service Manager was throwing an error popup with “Authentication with server failed” message. This environment was not setup recently and it was working very fine earlier. But all of a sudden it started throwing this error and stopped working.
We did check all the server configuration and services nothing seemed to be wrong. But finally we found that in K2 and K2 log databases we have _procUsers, _ServerUsers and _ProcRights tables. These tables were having some user ids for same proc set id for more than once. So that was causing the issue. We took help of K2 guys and removed all these duplicates. It again started working fine.
Not sure why this error says authentication failed instead of showing something related to these duplicate user records message. But you can find the correct message when you start the K2services through console in the K2 Server (logon with Service account) or Server event logs.
Hope it helps
