Really I'm after a way to narrow down which process/driver is causing the disk thrashing as it has to be something on the system level as there isn't really much running on the server itself. -- G2 Support Network Support : Online Backups : Server Management Web: www.g2support.com Twitter: g2support <http://twitter.com/home?stat...@g2support> Newsletter: www.g2support.com/newsletter From: Sherry Abercrombie [mailto:saber...@gmail.com] Sent: 26 October 2009 12:31 To: NT System Admin Issues Subject: Re: Whats thrashing my disks? Anti-virus would be the first thing I looked at.

It appears to grind to a halt and during which time perfmon shows that the write queue for the C drive goes sky high, easily reaching 200+ and it has gone over 4000+. During these times it effectively vanishes from the network with users not being able to access any of the shares or even RDP until the queue length settles back down to normal. This can take 20 seconds or 10 minutes with no real pattern. Any ideas where I should start looking? Olly -- Sherry Abercrombie "Any sufficiently advanced technology is indistinguishable from magic."
