exchange 5.5 imc won't start

Hello All,

I have an urgent problem. I'm running exchange 5.5 sp4 on a W2K server.  Recently the IMC kept shutting down- event id 4116.  I followed the suggestions on the Microsoft site and rebuilt the IMC and then ran performance optimizer.  Everything worked fine for 2 weeks.   Now, once again, the IMC is shutting down.  This time deleting the IMC an running Optimizer hasn't helped.  I'm still unable to start the Internet Mail Service for the IMC.

I'm in a real bind here - Microsoft refuses to help even though we intend to migrate to Exch 2003 next month.  Please advise. Thanks.  -Alicia

Do you have the Post SP4 Hotfix Rollup installed?  If not, installing it may fix the problem.

I'v tried method 2 - reinstalling the IMC and still teh service will not remain started for more than several minutes.
Sometimes messages hang in the conversion queues of the IMC. Use the following link to check and delete any messages there. You MUST be logged in as the Exchange Service Account to do this.

Thanks for your help.  One of the links suggested that the virus scanning software may be responsible.  So, I removed MacAfee and Groupshield from the server and the IMC started successfully.
