Environment: LinkSys Cable/DSL Router DHCP server LinkSys 10/100 8-port switch 3 clients running 1GHz Win98se with ethernet 10/100MHz TCP/IP 1 IBM file server 400MHz Win98se ethernet 10/100MHz TCP/IP Problem is with installation of new client Dell 1.8GHz GX240 with XP-Pro. - machine has the default user configuration as provided by the setup of XP-Pro. - I would assume this to be with admin/power user rights. A 32-bit application is executed from the file server. This application is accessed by mapped drive at each client. Each client accesses this 'served' application over a 10/100 ethernet network using TCP/IP.. and so far, it runs great under Win98se. The XP-Pro can access the application, but it runs 10 times slower than the Win98se machines. The XP machine has a processor that is 2 times faster, but runs 10 times slower?....?...? The application is only slow when transferring data across the pipe. Any and all network access times are considerably slower than the comparable 98se computers. What is odd is that the internet access appears to work fine. I have discussed the issues with Dell, and have installed the latest network drivers. The firewall in XP is disabled. I have even tried to assign the XP-Pro machine with a static IP address, but this did not cure the slow network connection with the 98se file server. I have discussed the issues with the application vendor, and they do not have a clue as to what may be going on either. File sharing, network printers, etc. all work fine. It's just the slow lag time for the application running on WinXP-Pro. The problem only seems to manifest itself when accessing larger amounts of data over the network, such as large ASCII files to be parsed, and pulling queries out of MDB files. Remember that the Win98se machines run these same functions fine with little to no lag time. Printing and file sharing appear to work ok, probably because of their short run time. I have read about a network bandwidth throttle that is now included with XP. The application speed is the same no matter if Qos is enabled or disabled under network settings. Any clues are welcome.

one thing is to try to check the nic and see if it is capable and function on 100 full duplex. i think the routers are auto neg, .... just an idea

you might get some good tips here for networking http://www.regedit.com/

I have the same problem, have not been able to figure it out. If you find the answer please let me know

One thing I have found with XP is that (for no known reason) it creates a lot of extra network connections that you don't need. You won't see these connections in network properties so you have to go to the registry. If you look in hkey_local_machine\software\microsoft\windowsnt\currentversion\networkcards you need to see if you have more than one NIC loaded in here. If there are NIC's in here that you are not using in your system take them out. All you have to do is click on the folder and it will tell you which NIC it is using in the preview pane. When you access the network the browser service searches through all of these cards for a connection and this is what makes network access slow. Hope this helps!!!

Exactly the same thing here. We have 6 computers in a local network. All three XP Pro machines are dreadfully slow to open the network and their data throughput is apalling. The Win98 machines can access the XP Machines and retrieve data as quickly as ever. It is quicker to walk to the other computer and get data than to wait for the XP machine to send it! Internet and printing are apparently unaffected. Interestingly data from XP to XP seems a bit quicker than XP to Win98 machine. Why we bought Pro version I don't know. Is it possible to identify and remove the extra functionality?

Finally a partial cure which I found on the Internet. In Win XP Pro (or XP I assume) "Run" the following program (sans quotes) "control userpasswords2". Go to the Advanced tag and then Manage Passwords. Remove the entries that you will find there. This does NOT speed up the Network page appearing but when it does the computers appear like a flash AND data flows MUCH quicker! I can only assume that WinXP requires a password each time it contacts another machine (possibly before it sends each block of data). This removes this delay entirely.
