ISA Server Windows 2000 Hangs / Freezes

Most of the time, it is fine.  However, occassionally, it will hang or freeze.  We have it set to restart services, so sometimes that works, but it disconnects all vpn users and the website running behind it also can't be reached.  Rarely, it blue screens.

We are running windows 2000 and e-Trust by CA, which, when viewing the modified files for around the time the server hangs, it was trying to go out to get an update.

Also, the event viewer reads:

WMI ADAP was unable to create object index 3302 for Performance Library W3PCache because no value was found in the 009 subkey

Anyone know what could be causing this???

Please help.

Sounds like it's trying to do the Scheduled Content Download or refresh cache using the Active Caching feature.  Unless you have a compelling reason to use this you should disable Active Caching.  As far as Scheduled Content Download - these are manually created so there wouldn't be anything setup by default.

Open ISA Management
Expand your server
Right Click Cache Configuration and select Properties.
On the Active Caching tab, uncheck the option for Active Caching.

Have you updated ISA to SP2 yet?

Thanks - I turned off active caching and checked to make sure SP2 was up.  Also, I uninstalled e-Trust by CA - it was the last program installed and it seemed to hang when it went for updates.
