After a fresh reinstall of SBS 2003 and application of all crucial SP's per the Analyzer, I continue to receive errors.
This one appeared literally dozens of times in a row upon reboot:
Event Type: Error
Event Source: MSExchangeAL
Event Category: LDAP Operations
Event ID: 8026
Time: 8:12:41 AM
LDAP Bind was unsuccessful on directory dell1420.xxxxxx.local for distinguished name ''. Directory returned error:[0x31] Invalid Credentials.
What to check/do?
