Re: Server 2003 reports 512Mb less RAM...

Hi William,

No /3GB switch is also mandatory when you have application like Exchange
running on servers with more then 1 GB of physical memory. There are other
application or secvices that can use this switch e.g. SQL...

I am not a specialist on the hardware. Maybe best one to ask question about
your hardware would be HP.

The difference between your two servers is that one uses 2GB of physical
memory and the other one is using 4GB... I saw these problems reported
before on server that had 4GB of physical RAM.
