My 64bit Windows 2003 (Standard) systems don’t need this but even good ole Windows 2003 Enterprise won’t pay any attention to more than 4GB of memory unless the /PAE switch is on.
If you have Exchange, you will probably want the following (as it can’t really use more than 4GB of memory – http://support.microsoft.com/kb/823440/en-us:
/noexecute=optout /fastdetect /3GB /USERVA=3030
This is a good article about what to do with an Exchange Server with more than 1GB of memory… http://searchexchange.techtarget.com/tip/0,289483,sid43_gci1241223,00.html
Then, after reading 100 articles about how one should never use the PAE switch in Exchange, I find that one of the sites I actually pay attention to, now says /PAE is supported in Exchange.
*sigh*. I guess this is why we are supposed to test software/settings 🙂
