Microsoft Server 08 x32 SP2 Enterprise (fully up to date)
I have a server that has 16Gb of RAM, however...in the task manager, and resource monitor are showing as only 3 gigs.

When trying to change the page file size to something larger, we can't.
Under Performance Options --> Advanced shows as the total paging size for all drives as 3366MB,  Anything larger than 4096MB reports the following error.

"Enter a maximum page file size that is greater than or equal to the initial page file size, and less than 4096mb"

32 bit O/S will not support 16GB of RAM

You need 64 bit O/S

Are you SURE this is the Enterprise version?     The memory limits you're seeing are consistent with Server 2008 Standard .... but Enterprise should "see" up to 64GB with the 32-bit version.

If it's definitely Enterprise then check your BIOS to see if it's set for an "install" mode -- some BIOS's allow limiting memory for OS installations -- and need to be reset for all the memory to be seen.

per the chart you sent, it's possible for Server08 x32 to run that much RAM, but PAE needs to be enabled.

I do believe that is the fix. Thank you sir.

You need 64 bit, Enterprise or Datacenter version

I forget about the other versions, your system as it stands will not be able to pick up the memory from the sounds of it.
