HELP Urgent: Update Rollup 1, Win2K SP4 MSDTC Error

[Diane]

After installing the above on our exchange 2003 server, I am receiving event
4099 as follows:

The run-time environment was unable to initialize for transactions rquired
to support transactional components. Make sure that MSDTC is running
(DtcGetTransactionManagerEx(): hr=0x8004d01b.

I am also receiving a few event 4156 MSDTC errors.

String message: Session idle timeout over, tearing down the session.

I have searched for error 4099 and everything I have found relates to
clusters. This is a standalone server. I understand this roll-up include
MS04-012 a cumulate update for RPC/DCOM which seems to be the issue.

Can anyone help resolve this issue or should I uninstall the update roll-up?

So far, from what I can see, applications are running OK.

Thank you for your prompt replies.

I removed the Message Queuing Service which has resolved the error. Still
not sure why I was receiving it initially. Would appreciate any ideas in the
event that I need message queuing at some point.

Thanks for your thoughts on the matter.
