I use SQL Serv 2000 running two noded cluster on W2K SP3. When i move group from Node2 to Node1 i get these in System log: "Logon attempt with current password failed with the following error: Logon failure: unknown user name or bad password" "The SQLSERVERAGENT" service failed to start due to the following error: The service did not start due to a logon failure." and the following in Security Log: "The logon to account: sqladmin by MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 from workstation Node1 failed: The error code was: 3221225578" "Logon failure: Reason: Unknown user name or bad password User Name: sqladmin Domain: MYDOMAIN Logon Type: 5 Logon Process: SCMgr Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Workstation Name: Node1" Moving group fails, gets back to Node2 and works fine on it. Server Agent runs from account MYDOMAINsqladmin and the password set there (via Enterprise Manager) is the same as for the domain user sqladmin. As you can see the problem occurs only with Node1, on Node2 everything works fine. Are the passwords cached locally on nodes or what ? Any ideas ?
