When someone tries to connect to a SQL Server instance, the error shows up:
It's not possible do generate SSPI context.
Yesterday we had a blackout (don't know how to say this expression in English) and I had to shut down our servers.
Looking for answers, I found this:
SQL Server 2008 connectivity issue : cannot generate SSPI context
But it doesn't help me, because they're working fine until yesterday. I don't want to change anything. But if a have to, I will change it.
Obs: I can't restart the server now.
Edit: Since I my answer, we haven't had any errors.
