Server 2003 AD network with 7 XP Pro clients. If I browse to server file system from any client and attempt to execute a program residing on the server's file system it takes 8 minutes to start the application. Navigating to the server is instantaneous, pings are instantaneous, QBooks clients have excellent performance to QB database engine running on server. No firewall yet nor antivirus (behind NAT firewall but they come after the network and systems are up and running). What am I missing?

How long does it take to transfer a file about 50MB or so?
Let's find out first if it's having trouble transferring large files.
Pings and actions like that send only a single packet, which may seem like it's responsive....
We've seen MTU size problems as well as:

Also, what do the event logs say?

Is the NIC running on 100 MB FULL DUPLEX? (Autonegotiation ok)

It appears that a 96MB file (openoffice2_1_0 binary) will take 51 minutes to copy. The server is hooked to a Gb Dell switch. I am configuring the server to use GB Full Duplex and set all of the clients to 100 Mbps Full Duplex. Our network all cat 5e.

Make sure your switch ports are also set to 100Mb/Full....therefore there is no autonegotiation.

Also, this is a biggie.....

Thanks, I am on the phone waiting (long wait, it appears) for MS networking support so I will incluide this informatin too. As for the switch, it is a Dell 16 port gig switch set to non-manage mode. I will have to do some research to see how to set this thing up differently.

For $245 per call to MS, I'd try this first!!! I've seen MSKB #328890 happen lots.

Yes, since this is a new install it is still on their nickel but I am looking at the information you sent while I wait.

Excellent! Use their resources while they are available.
I wish you the best of luck and hope to see that you solved it. I know how frustrating this can be.

Normally the autonegotiation on both sides is the best option. But if the switch ports are configured to 100 MBit manually be sure that the NIC on the servers OS is also set to 100 MBit manually, otherwise qou have a speed mismatch that will decrease network performance to about 10% of the possible rate.

On the Switch, you can check via login (telnet) and a command like show port (depending on the switch OS). You network administrator should be able to verify this.

Well, it appears that Microsoft fixed this problem. After two seven hour nights online with them the client's boxes are working acceptably, except for two clients (I guess I really need something to do next week anyway.)

I am very sorry to say that I cannot much, if any, light to the resolution as I was on line with their "Expert Assistant" application with two levels of network support engineers. There were so many quick changes of this and that in the registry and nothing that seemed to be a methodical approach but lots of data acquired through experimentation. I have asked the network engineer to help me identify what was discovered and how it was solved and I will post that information here.

The one thing I did discover is that both the first and second level support folks stated that my current system, server 2k3 r2 was at a level that included the hot fixes mentioned above.

Here is a link to the last action taken to resolve the problem with the slow file transfers from our Server 2k3R2 box and our XP ProSP2 clients:
http://support.microsoft.com/kb/279282/en-us

There were a number of other items that were changed that I missed in the flurry of keystrokes but the MS folks assure me that this was the "real fix".

We still have two clients that are slow and I will be attacking them on Wednesday. More data when they are fixed.
