One of my clients as an odd issue that is causing company wide issues. They have a Windows Server 2003 running as a NAS server. It ha been running fine until about two weeks ago when the server started to hang. These haopen, mostly iovernight but it has occurred once during the day.
The only way to get the server up is to manually power off &back on again.
When the server hangs no users can log into their computers or even to the clients Citrix XenApp farm.
All network drives are on the server as well as users Profiles (hence the log on issue).
There is nothing in any of the logs. As the server has hung nothing is written to the logs. The server doesn't blue screen just hangs. When it happens and we try to log in, we get the grey 2003 server background and nothing else. We are able to move the cursor around but nothing else.
I have tried the following:
Disabled Backup system (using Jungle Disk)
Run full AV Scan and no infections
Disabled AV (using Kaspersky)
Run Windows Update - all up to date
Dell Server Administrator (its a Dell PE2950 running as a Power Vault 500) reports no hardware issue or firmware upgrades needed. Power has full redundancy (second PSU is on a UPS).
Server is on SP2
Today I'm going to run spybot on there but given that there are 3 TB's of disks on there its going to take a while!!
Any other suggestions?
