SBS 2003 Domain Randomly Freezes

Hello Experts,
On a small domain which an SBS 2003 server is the only server, domain freeze up is occurring about once every 1-2 weeks. Hard resetting the server fixes the issue. When this occurrs, all computers crawl to a near halt. The computers behave like they no longer resolve DNS correctly. The still function but extremely slowly. I used to have a second server 2003 secondary domain controller on the network but removed it...thinking it might might be the cause of the issue but the freezing is still occurring. Could this be a master browser issue? The only clue I have is I have found this in the event log before the freeze up:

A process serving application pool 'DefaultAppPool' failed to respond to a ping. The process id was '3784'. SOURCE=W3SVC EVENTID=1010. I checked and this point to IIS not being able to communicate but I am thinking that could just be another symptom...not the cause.

The server I am running is a Lenovo Thinkserver TS100...although the issue does not seem to be hardware related. I observed this on another domain as well running server 2003 but have not found the cause there either.

Any Ideas Anyone? Thanks!
