What is the best method of diagnosing a resource shortage reported via a\npop-up window, with a red button containing an X, after invoking a program\nsuch as mmc.exe, or one of the snap-ins such as enterprise manager? I've used\nthe performance monitor and added a counter for memory and it does not appear\nto be a memory shortage. I've checked the disk drives and threre are no\nquotas. What other system resources to check? And how?
