I'm currenlty running AS 2005 on a Windows 2003 STD edition 32bit.
I have added the /3GB switch in the boot.ini to that the server will use all 4GB.
Unfortunately AS only appears to see 2GB based on the following error
Memory error: The operation cannot be completed because the memory quota estimate (4095MB) exceeds the available system memory (1996MB).
As you can see my the error AS only thinks the system has 1996MB of memory.
I can confirm that there is 4GB of memory in the server and the OS can see 4GB memory
Thanks for your help
