Andrew, Check the links below for some more info on the /3GB switch. It is intended for W2K Advanced Server and W2K Datacenter Server, except for some special circumstances. User mode is still limited to 2 GB when this switch is used on W2K Server. http://support.microsoft.com/default.aspx?scid=kb;EN-US;q291988 http://support.microsoft.com/default.aspx?scid=kb;EN-US;q298064 http://www.microsoft.com/hwdev/platform/server/PAE/PAEmem.asp http://www.dell.com/downloads/us/pedge/exchange2000.doc

Someone sent me a MS doc talking about why you wouldn't want to run this switch on a production box - I could probably find it if anyone is interested. /3Gb seems to be much happier on Win2000 Advanced server though, it actually does something. Has anyone persuaded any version of Windows to use more than 3.1Gb of memory?

The Virtual memory error is showing up every hour in the event log. The Server is E2k SP1, with about 800 users. We had a few issues with messages that got delayed in sending out to the internet, it looks like they were getting stuck in the SMTP connector. Thanks for any help!
