LDAP Bind Unsuccessful
Posted on 2010-09-20
Have 1 Exchange 2003 sp2 server, (not a DC). Have 2 DC’s that are also GC’s. Every 15 minutes or so receive errors in Event Viewer. Errors are 8026 and 8260 (LDAP Bind was unsuccessful… and Could not open LDAP session…). During these errors, members are unable to open Outlook accounts. Also getting Event ID: 2102, (all domain controllers are not responding). Also ID: 8250 (the win32 api call 'dsgetdcnamew' returned error code [0x54b])
Both DC’s are up and running fine. Can ping from exchange and run LDP and bind to them.
Dcdiags: all tests pass
Dnslint: all ok
SeSecurityPrivelige is ok(Exchange Enterprise servers listed under manage and security log)
ExBPA: there is an update for NIC’s,
Exchange NIC’s have the proper DNS and Wins listed
Could NIC’s needing update cause problems like this?
