Slow Windows 2008 Server

Hi

Running Windows 2008 SP2 server.

One of my application servers is running slow. The application owners say it's not them - I would like to rule out anything to do with the OS/hardware.

Can anyone recommend any Perfmon counters to use (memory, CPU, that sort of thing) and what their recommended values should be?

The problem here is you need a baseline to compare to.  There are no magic numbers for performance counters to say this is bad, this isn't.

Some key counters that indicate a hardware failure are:
System\Context Switches/sec - This value should remain fairly steady.  A large spike in this counter could indicate faulty hardware
Processor(_Total)\Interrupts/sec - This should spike with Context Switches.  If it does not that would indicate an application issue.
Process(instance)\% Processor Time - This is good to see which applications are calling all the processor time.
