Get Latest Version extremely slow

Question

Hello,
When we do a "Get Latest Version" for a project containing about 450 subfolders this operation shows the "Contacting server to get list of items to update..." for a very long time. Eventually it will come up with an error "HTTP code 500: Internal Server Error". The event log indicates a time out. I have already increased the executionTimeout values for the various .config files used by the Web Services. This increases the time it takes for this error to appear (this can take up to 2 hours) but the error still appears. These subfolders each contain about 20 files with a total size in each folder of 180KB. 
While the "Get Latest Version" is active the server CPU is not busy at all, it stays at 1-2%. It does not matter if we do the get latest from a client or on the server itself, the result is the same. It looks as if Team Foundation is blocked on something.
When we do "Get Latest Version" on a smaller project (2250 files, 272 folders, total size of all files 134 MB) the operation also takes a long time, but it completes successfully.
I've only been able to retrieve all files successfully by creating a .cmd file which contains a get command for each individual sub folder:
tf get Folder1 /force /recursive
tf get Folder2 /force /recursive
tf get Folder3 /force /recursive
etc.
The execution of this command file takes about 20 minutes. During this time the TF server shows a much more substantial CPU load.
We are running our Team Foundation Server (single-server deployment) on a Dell PoweEdge SC440 server (3.0 GHz, 1 GB RAM, Server 2003 R2 Standard Edition SP1).
I have searched the forums for hints on these performance problems, but haven't found anything except instructions to look at the network configuration (half duplex/full duplex/auto detect). This can not be the issue since the issue also appears locally on the server.
Any help would be appreciated, we really need to improve the performance of the system to make it usable for us.
Regards,
Henk.

I'm sure there is a problem with our domain controller setup. When I had problems installing Team Foundation I found a post which advised to run a dsquery statement which does something similar to what the Team Foundation installation tries to do. When I tried this statement it failed with an error, at that point I decided to switch to using Workgroup accounts for the setup.
Having said that, I had no problems logging on to the Team Foundation server system using a domain account, but it does appear other parts of the Active Directory functionality are not working correctly. We do not have much Active Directory expertise at the moment, it's something we will look into later.
