Seems like you've got a REAL problem with your NT Servers ???

I actually had a NT Server wich crashed every once in a while (once a week or so) ...

It was build of the cheapest hardware available, with a Quantum Bigfoot disk (those 5 1/4 inch drives ... *argh)...

When the company moved, they of course moved the server with them ... but now it was installed in a grounded power socket, that moved the crashes from once a week to one time within 2 months ( all other machines in the building crashed as well at the same time ... power failure/surge??), then i installed Y2KSP4 on the machine .. and it havn't crashed since .....

You might want to look into a little UPS to help gain stability ??? - the OS has a hard time compensating for hardware failures :)

It had Several ... but it ran on a "closed" network ie. no direct internet access, and the users actually used the server and wasn't interested in nuking it ... so no problems there ... as i said .. the box have been disassembled and the OS reinstalled but the box is still running without a crash ...

Normally i don't install Service Packs unless theres a reason to do so ... the Y2K is a good one ... therefore all my servers now run Y2KSP4 ... even though i'm concerned that it ain't enough ... only time will show ...
