I have a problem with my IIS6/win2k3 server crashing unexpectedly.
The System Event Logs show this entry:

A process serving application pool 'MyApplicationPool' suffered a
fatal communication error with the World Wide Web Publishing Service.
The process id was '1236'. The data field contains the error number.

The time on it is 11:00:04AM, 4 seconds after a scheduled incremental
backup using the Windows built-in backup service.

Fortunately, I had IISState running and was able to catch some logs.
I was told to post them here in their entirety and that someone might
help me read them. The IISState debugger closed down the logger right
at 11:00:00am as well.

I am 99.9% sure that the ntbackup is causing this but this crash
happens at other times as well, when im not backing anything up. But
ill post those IISState logs later. Here's the logs from 11:00:00AM
today:

[I figured its easier to link to the file rather than paste it in this
thread for readability's sake.]

Thanks
