User's cannot login to OWA logon screen just hangs. Server was rebooted but that does not resolve the problem. SCOM only shows a Memory Pool Non-Pages Bytes High alert.

Hi, Nonpaged pool memory is a limited resource on 32-bit architecture systems. It is dependent on how the server is setup to manage memory and is calculated at system startup. The amount of nonpaged pool allocated on a given server is a combination of overall memory, running/loaded drivers and if the /3GB switch has been added to the boot.ini file. Mike legasy had written a very good article on this, Please go thru with this to fix this issue.

Ifyou're running out of critical memory then IIS is going to stopaccepting logins to prevent a complete exhaustion of that memory.You may have a memory leak, or a badly configured, or overloadedmachine.---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP
