Hi, I have a problem with my exchange server. I have a Exchange server5.5 on a Win2k server platform. The mail service was working well, but suddenly the users can not log in their mailboxes. The mail client (outlook express) asks for the password again and again, but never accepts it, and the passwords are correct. In the event viewer of the exchange server there is a message that says:
"Logon attempt from 172.26.34.114 to rcobos has failed: HrLookupCredentials() call failed with error Logon failure: unknown user name or bad password"
The password is OK, and when I want to re - attach the service to the user who starts up the service the following message appear:
Processing of object exchange failed with the following error: Ther remote procedure call failed and did not execute
Where exchange is the name of the exchange administrator account
Please help me....
