Hi, I just installed more memory into my Windows 2000 Professional Server and am up to 6GB. It shows as such on the boot up screen. However, when you go into task manager and look at the total memory of the system, it is 3.7GB. After the install, my network team researched and found the following article: <http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx> Apparently, the limit for my server is 4GB. Why is there only 3.7 showing in task manager and not 4GB, and does anyone know what I can do to get the server to use more memory, al least the full 4GB? Thanks.
