SBS2003 won't boot because boot up service won't stop.

Office a/c was shut off, inexplicably, over weekend--we think is was bldg maintenance. We came in to find SBS2003 up and running, but w/ a lot of issues.  We re-booted and system will not boot up.  Our technicians, after being on the phone w/ MS tech support, believe that the server will not boot because a boot up service won't stop.    They summize it is an O/S problem. It's mirrored drives do have data that they believe they can recover.  And we just recently backed up Exchange Store, WIN, DNS, user folders, etc.  However, those backup files were on another server that we, at the same time, found shut down, and 3 of the 4 partitions on its mirrored drives have failed as well (each drive had 2 partitions.  Office temp was ~80 F, but server location could have gotten as hot as 3 servers can get in a closed room under a desk.

Two questions:
Question 1: What is the likelihood that so many problems could have been caused by a hot office for a few days?

Question 2: What should we do to avoid future recurrances? Buy a portable a/c unit?

UPDATE:  SUPPOSEDLY THEY HAVE NARROWED IT DOWN TO THE NETLOGON SERVICE.

I'd not be surprised if the problems were caused by the temperatures, conditions like you describe (small server room with failed/shut off air con) have probably been responsible for more of the drastic server failures i've seen than any other cause - are the servers on UPS or is it possible they went down over the weekend as well?
A portable AC would be a good solution, and if it's possible the AC in the office will fail over a weekend again i'd say it's essential - it might be worth looking at some monitoring software so the servers can be shut down if conditions in the server room get too hot for them.
The boot up problems are most likely down file corruption on the hard disk - a tiny amount of damage to critical system files can easily render the server unbootable, and if conditions have got hot enough for the disks to stop working properly it's not surprising it happened on both servers.
