I have a Windows Server 2008 sp2 with 8 gb of ram installed.

This can be seen in the screenshot.

The issue is, in Task manager it reports 4 gb of physical memory available.  How can I fix this? As you can see, this server really needs that last 4 gig of memory!

You can't use more then 4Gb in a 32-bit system which your install says you are running Windows 2008 Server 32-bit this is a limitation of the Standard edition.

You must install the 64-bit edition to use more then 4GB of RAM or install Enterprise 32-bit edition. I would recommend going with 64-bit instead of Enterprise since 64-bit can really utilize the extra memory.

The reason the page show 8GB because the server hardware can see that must RAM but the OS can use that much RAM. The screen you are viewing is from the BIOS infomation.
