Don't you just love users.....
I remember one of my NT4 TS's died due to a memory overload. It had 4Gb of RAM and over a 12 hour period, the memory usage slowly went up and up until it the server hung for about 30 seconds
..... and then BSOD!!!!
I think it had 40 users on it at the time running old 16bit apps that had a lot of memory leaks!!!
My support team were betting on how long it would take to die....
