'Waiting...' error on Windows Server 2008

We have a new HP ML110 G6 server with an Adaptec 1220SA RAID controller that we have just installed Windows Server Standard 2008 on to. It is joined to the existing domain, which runs an ISA firewall.

The server drops randomly during the day, at which point we can ping it but not do much else. Looking at the screen, it looks like the standard Windows Server 2008 logging in screen, but it just says 'Waiting...' - that's it. We have to switch off and reboot the machine for it to function again.

Any ideas as to what this could be?

Nothing conclusive is shown in the Reliability Monitor, all it has logged are 'Disruptive Shutdowns' where we have had to force the machine off when it has the 'Waiting...' screen displayed. The Reliability index is down to 6.9 though.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

what about the perfomance monitor? Can you check for CPU / RAM Usage before the Server hangs?

Did you checkd the Harddrive for errors? Malware check?

Jim JonesAuthor Commented:
Malware check is clean, performed CPU and RAM stress tests and they passed. Hard drive not yet checked as it would involve downtime.

We have constant monitoring on the server using GFI Max and the CPU / RAM / Network usage doesn't increase when the server is about to hang.

Can you check event viewer for errors ?  It could be wrong DNS settings where the server is looking for the DNS server and cannot find it. What happens if you boot it in safe mode ?

Replaced the server with one running Windows Server 2003 and all problems went away. The problem seems to be that Windows Server 2008 and ISA 2004 are so incompatible that it brings the server down.
