I have a client with a W2K fully patched SBS server. The server has 1.5gb RAM. The number of Exchange users is around 10. When Exchange store.exe loads initially resources in task manager are of 10,000k range, however this rises over a number of days to around 850,000k and stays at that level. I am wondering if this is "normal" given that W2K SBS does not use the /3gb switch in boot.ini. AV checking is correctly excluding drive M: and specific Exchange folders. Any observations or additional things to check ? thanks Simon
