IIS/SMTP Services disappear from Windows 2003/Exchange 2003 server services list

For no known reason, my Exchange 2003 Services stopped operating on a Windows 2003 SP2 server; this happens from time to time but restarting services or restarting services usually clears it up.  When I checked services in this instance, the Exchange related services were stopped BUT the IIS/SMTP services were NOT in the service list at all.  I have no suspects for deleting these services so I need to know if this has happened to others.

I'm currently running a full Exchange backup before proceeding with troubleshooting, in large part based on Microsoft KB 320202 which I found in response to a search on the Exchange error 1083 when failing to start the Microsoft Routing Engine (although all other services do start).  This may address getting IIS/SMTP and Exchange back in operation but not the underlying issue of  how/why IIS/SMTP disappeared in first place.

High points for weirdness and priority.

 I'll be back in a few hours to check on responses... please don't consider a delayed response as a lack of interest -- I'm rebooting my brain while the backup runs.  Thanks.

nskurs:  OK to use a free Trojan Scanner, such as from WindowsSecurity.com?  I'll be looking over the Event Logs again but I didn't see anything immediately suspicious.  With fresh Info Store backup in hand, will follow KB 320202 which has me moving MDB-database to an "old" folder to protect it during the reinstall... thanks for quick answer.  I'll be back in touch as the recovery process moves along.
I appreciated the timely response; KB320202 was key to recovery but your hints were helpful and I picked up a virus/trojan scanner too.  Thanks!
