Well.. ive been doing some reasearch after i encoutered a problem, but i just don't know it anymore..

We have a TS server with 6Gb of RAM. It uses 32bit Win2k3 Enterprise with the /PAE witch enabled. So far, ive read thru different techdocs and made some conclusions. Please feel free to shoot at my conclusions as i dont know if they are right..

So here it comes;
Theres a true PAE and a x86 PAE. True is 64bits procs with 64bits windows, x86 PAE is an extension for 32bits procs and 32bits windows. All i've read is that x86 PAE lets u use more than 2Gb of ram for the kernel. I am not interested in the 2Gb limit apps like SQLServer or Exchange have, but in the kernel memory size so my users have more ram than the 2Gb appointed to the kernel. The appliance is TS here.
So why cant i use my extra 4G of memory? The server says it has 6Gb of ram, but doesnt use it, coz theres 4Gb available while the server is swapping and very very busy.

Another question i have while trying to understand the problem is that ive read that the virtual memory appointed to a app is 4Gb on a 32bits Windows server system. Is this devided in 2G for the kernel and 2G for the app-pool? If so, is this why my TS almost doesnt access the 4Gb? Coz the apps wont ever have use for more than 2G mem?

So my questions are;
-Why cant i use memory for my TS above 2Gb with the PAE switch enabled?
-Do i have to do a reinstallation of Win2k3 ent to support the memory above 2Gb? or is adding the /PAE switch enough?
