Our server started freezing after a reboot. It freezes every 90 minutes or so. I can still ping the server, also clients still have the internet connection - those with static IP's. DHCP client's can't access internet. There is also a Raid array. I already tried with disabling Non-Microsoft services. No luck at all!

When you say it freezes, do you mean you have no control over mouse and keyboard as well. If so, download this program called Speedfan and make sure the cores to the processors are not above 52 Degrees C.

Also open up the casing to the server and see if it last longer before freezing. Put an external fan directly on it and blow cool air to it, (not wet).

Mouse and keyboard respond only for few seconds and then they freeze. I already installed Speedfan but everything seems normal, all the temperatures are below 50 Degrees if i open the case. It still freezes.

When a mouse and keyboard freeze, this is a basic Input/Output problem. Usually this is caused by heat on the processor core. Typically the carbon within the CPU doping heats up and expands. This expansion causes resistance to the point that traffic will slow and basic Input/Output will freeze. Since speedfan reported the core temperatures on the CPUs as below 50 degrees, it would appear that this is not a heat issue and the CPU hasn't expanded to slow and freeze the computer.

Input and output devices, like a keyboard and mouse can also freeze when you have a bad memory module. However, this typically causes a blue screen of death. You could elect to perform a memory test, if you haven't done so already.

Drivers can cause freezes with memory leaks. Another troubleshooting option is to run this in Safemode to see if the drivers are causing problems.

These are the simple tests. Complex tests will be provided after you reply back to confirm these are not issues.
