I wouldn't doubt that needing 512MB min paging space might be true for Windows 2000 but, for what it is worth, for those still running on NT4 - I used to run Exchange 5.5 SP3 on a Pentium 180 with 192MB ram running NT4 SP6a with the paging file set to 384 max and min with about 25 very heavy users (half gig mailboxes & shooting messages with big attachments back and forth to customers all the time etc.) and I didn't see this issue. That machine was also my BDC and main print server.
The only differences I see between the question poster's set-up and my set-up are: I got a new box before I got to SP4 so never had SP4 on that machine, and I had the paging file set with the same value for max and min. So I would suggest the following not necessarily in this order: perfopt, reapply SP4 for Exchange, reapply SP6a for NT4, and lastly, set the paging space to 512 for both max and min values (although that may not make any difference but I have seen it recommended to avoid fragmentation of the paging space). More helpfully perhaps, here is a possibly/probably useful Q article: Q172813 "XADM:Troubleshooting High CPU Utilization By Store.exe" There are also possiblities such as Q215924, Q230285, Q304228, and Q159297 depending entirely on the particular situation. All found using a search of "store.exe cpu utilization" (sans quotes) on Technet (cd version not web version). hth Ronni > -----Original Message----- > From: Christopher Hummert [mailto:[EMAIL PROTECTED]] > Sent: Monday, May 06, 2002 11:34 AM > To: Exchange Discussions > Subject: RE: IS Crashing, HELP > > > With Win2k anything less the 512 for the virtual memory can cause > problems.
