MrxSmb 3034 error

[RonL]

There have been several questions regarding this error,
but there doesn't appear to be any definative resolution.
So, allow me to add another log to this fire...

I have an AD infrastruture with two AD Controllers (both
GCs) - one of them is running SMS (coincidentally I
think). Anyway, the AD controller without SMS is giving
me this event log entry every 2 minutes:

"The redirector was unable to initialize security context
or query context attributes."

I've found the MS-KB article about Kerbose, and based on
other postings have checked the time sync and DNS
settings.

Other than this event log, there doesn't appear to be any
other symptoms. However, the fact that I get this every
2 minutes (like clockwork) tells me that something real
is happening. Also, I tend to get these entries in
groups...anywhere from 2 to 4 at a time - never less than
2 or more than 4.?

Lastly, I cannot say for sure because I didn't notice
these log entries right away, but I think this started
happening after I installed SP2 (I've even reinstalled
SP2).

Any takers for this challenge?
