Crashing and DHCP problem

Greetings,

Well, here goes...

I am running an x86 NT4.0 SP3 server which has been up, without incident, for a couple of months. Last week, I came in to find a blue screen/hex dump up on a crashed server. I swallowed hard, wiped the sweat from my brow and rebooted. It worked, things seemed to be just fine. Of course this didn't answer the "Why?" of the situation.

This morning (Monday) I came in to find my Win95 clients weren't finding the DHCP server on the network. I'm sure this problem existed last week but my leases hadn't yet expired. I eventually reinstalled SP3 and -BINGO- IP addresses flow once more!!

So, the question, what happened? I know there may not be an answer to this one but... Also, when I go into "SERVICES" I find a DHCP Client service loaded but not running. When I hit "START" I get the error "Could not start the DHCP client service on \\SERVER_NAME. Error 2140: An internal Windows NT error occured".

I have seen this happen a lot with 95 clients. It usually is caused by excessive invalid client shutdowns (not shuting down through windows but just shutting the power off.) This results in DHCP leases that are not un-registered as being dropped and eventually causes the dhcp database to become corrupt. The error your getting when you try to start the DHCP client service is due to the fact that you already have Microsoft DHCP Server service running and the DHCP Client will not work on the same server that runs the DHCP server end.
You may want to try to just stop the Microsoft DHCP Server service and restart it the nesxt time.

Hmm... Now I wonder what the initial crash was all about (the one last week). Is there a decent reference for understanding hex dumps? When I first found the DHCP problem I rebooted the server and got a Dr. Watson error window and still no DHCP. Of course I couldn't understand a thing in the Dr. Watson error window!
