Okay, I didn't get to play through this back in March with the release of MS03-010,
but I am not enjoying the same symptoms for it now. I've had no luck finding MS'
official work-around for it from the original discussion board posts.

Anyone else getting this recently?!?!
DESCRIPTION: Error: 8520, Severity: 20, State: 1
Commit of internal MSDTC transaction failed: Result Code = 0x8004d019.
It's an intermittent error for a linked server insert. The stored proc hasn't changed
in months and has worked flawlessly. No explicit transactions in the query. Now just
for fun and excitement it likes to barf once about every 45 minutes instead of
completing successfully. Grrrrr.

Yes, I know how to and will rollback the last security updates to find the offending
patch, if I have to do it, while I await the correction update to the update; thought
I'd ask if anyone had a quicker or easier known solution first.
