Here is the relevent KB article that fixed that same problem you are having on our domain controller. 

 

"New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003"

http://support.microsoft.com/default.aspx?scid=kb;en-us;328890

 

There is also a hotfix available if you call microsoft if this doesn't fix your problem.

Subject: [THIN] Re: Probably OT : Slow File save in W2k3 TS

Create a test folder on the network drive, create about 100 0K test files and test the copy performance on the network drive, is it slow?   There was an issue created by a Hotfix released for 2K3 in September, Microsoft has a registry fix to this problem I will dig it up if you need it.

 

In addition try disabling the legacy NetBIOS over TCP/IP to see if name resolution is causing an issue.

Subject: [THIN] Probably OT : Slow File save in W2k3 TS

I have a Dell 2450, single processor, 1 GB RAM, servicing about 15 users as native (Non-Citrix) TS, running Office 2003 (mainly) , and a few Sage users. Uses Roaming Profiles if that may be relevant.

 

Issue: Saving files (Word, Excel) is slow. Not catastrophically so, but slow; about 5 seconds for a 2-sheet word document, 10 seconds for a ‘similar’ spreadsheet. Of itself, that’s not *too* painful, but when writing to Journals in Sage it does become very painful.

 

 

Performance indicators are fine; lots of RAM, lots of Processor, hard drives fine.

 

If I save directly to the TS Local Hard Drive, saving is instantaneous(ish).

 

Which leads me to suspect a network/file server issue.

 

On the file server, all is again fine in performance terms. This is a Dell 2450, 3*RAID 5 HDDs. It is running Exchange, DNS, and a bunch of other stuff (AV etc), but they don’t seem to be taking up resource unexpectedly.

 

Is my RAID 5 likley to be a problem? Are there redirected Temp files that may be an issue? Anyone got any good pointers to show me where to start going?
