The lesson?  It appears that the loopback check described in the KB is alive and well in Service Pack 2 as well.

A quick interogation of the server security event logs revealed a large number of 537 events (Failure Audit) with what can only be described as gibberish (garbled characters) for the Logon Process.  For example:

Event Type: Failure Audit
Event Source: Security
Event Category: Logon/Logoff
Event ID: 537
Date: Date
Time: Time
User: NT AUTHORITY\SYSTEM
Computer: Computer_Name
Description: Logon Failure:
Reason: An error occurred during logon
User Name: User_Name
Domain: Domain_Name
Logon Type: 3
Logon Process: Ðùº
Authentication Package: NTLM
Workstation Name: Computer_Name
Status code: 0xC000006D
Substatus code: 0×0
Caller User Name: -
Caller Domain: -
Caller Logon ID: -
Caller Process ID: -
Transited Services: -
Source Network Address: IP_Address
Source Port: Port_Number

As luck would have it, Microsoft has a KB article detailing this exact behavior (KB896861).  The farm was indeed running Windows Server 2003 Service Pack 1.  A quick trip to the registry did solve the issue.  At this point it was determined that we should upgrade to Service Pack 2 as support will be ending for Service Pack 1 in 2009.

The strange thing is that we had not recently applied any updates to the servers (although we had recently updated the Alternate Access Mappings (AAMs) for the farm.
