When I boot up my server the machine hangs and I get a service failed to start error message. The event logs show me that it's related MTA Stacks, but MTA check shows no issues, and eventually Ican start the service. I know the info is pretty general, but I noticed something today, that I didn't catch before. Listed in the MTA Stacks Service Dependencies is a service called NT LM Security Support Provider. It is running, but set to start manually. I have never started this service and was wondering if thats the cause of the hang up at boot. Is the MTA Stacks Service failing because the NT LM is set to manual? Exchange 2000 has SP3 and the box it's on is a Win2K Server SP 4. Any help that can be offered is much appreciated. It's not critical since Exchange eventually starts. But it sure would make life better if things booted easier.
