Windows Server 2003 event id 2001 &2003 Shadow copy causing firewall svc to crash

Please help!!

I am working with windows server 2003 and isa server 2004 about a week ago the firewall sevice started crashing mysteriously after daily reboots.

The first error is usually "The ISA Server Web filter failed to log information to file ISALOG_20100824_WEB_000.w3c in path E:\ISALogs\Web Proxy. The data is the error code."

Followed by "The Firewall service stopped because an application filter module C:\WINNT\system32\msvcrt.dll generated an exception code C0000005 in address 77BC6F76 when function CompleteAsyncConnect was called. To resolve this error, remove recently installed application filters and restart the service."

After that a bunch of cannot write to cache errors.

At first i believed it to be a problem with the urlcache so i deleted it and it recreated itself.
-no dice

 I know that if it cannot log the firewall stops. I made the isalogs an exception in the anti-virus scan. Then i realized that the logs were over the size limit so i increased the size limit and made the logs delete after 3 days which got the size down plenty.  I thought the problem was solved because it went away for a couple of days then returned.

Then one of my coworkers noticed a trend of information events before every single crash.

1. Event ID 2001: lsass (512) Shadow copy 2 freeze started.  -Source ESENT
2. Event ID 2001: wins (3176) Shadow copy 2 freeze started. -Source ESENT
3. Event ID 2003: lsass (512) Shadow copy 2 freeze stopped. -Source ESENT
4. Event ID 2003: wins (3176) Shadow copy 2 freeze stopped.-Source ESENT

Then the crash

Im in the military and I'm sure our servers aren't set up 100% properly. I've been working with computers for quite some time but am very new on servers. So please explain solutions so i can understand.

Thank-you very much!!

Check your cache and disable it for a while. Try to start the service and monitor. Once it's up you can restart the cache.

Yeah disabling shadow copy only caused VCC errors. the firewall shut down still. I noticed that the shadow copy service was set to automatic but did not start im gonna try and start it and see what happens.

What backup software are you using for the server and are you backing up the URLCACHE during the backup?
Does the ISA server crash around the time the backup is running?
If so, please exclude the URLCACHE directory from the backup and see if that improves the situation.

Hmmm...i haven't thought of this.

I thought i tried every thing. Starting to get worried. But it does crash around backup time right after nightly reboots.

We use Veritas 10.0 to perform backups.

-Thank You-

I will respond later tonight i work the night shift but thats when we have maintenance hours so ill let you know what happens.

There is a known issue with a number of backup products that causes the Extensible Storage Engine (ESENT) to crash.  Make sure all Windows and 3rd party products are upto
