I helped a friend purchace some new PC's for his small business. We purchased 5 Dell's, Intel Core 2 Duo E7600, 2 Gig RAM, 250Gig SATA drives, 1Gig - onboard NIC (sorry don't remember the exact card) and Windows 7 Pro 32-bit. We replaced a few Dell Latitude 630's with Windows Vista (again sorry, can't remember what version of Vista). Anyway, after setting up the new PC's, I found copying files from the server (Windows Server 2003) to the Windows 7 PC's, very slow. For example, if I copied a folder containing 40 file totaling roughly 200Mb from the server to the PC, it took less then 5 seconds. If I tried to copy the same folder, after renaming it, back to the server. It starts out at 20+ minutes. I sat and watched it for about 7 minutes, and ended up canceling the copy. If I connected the laptop to the network, the files moved relatively the same speed to and from the server. It was a bit longer then the 5 seconds, but the laptop also has a slower NIC. I did a bit of searching, but didn't come up with any solutions. Can someone please advise?????? Thanks, MIKE

Hi Mike, Check the Dell driver downloads for a newer NIC driver. Check your device installation settings are set to check for driver updates and see if Windows Update offers a newer driver. Is the card connected at the correct speed? Cheers, Rob

Thanks Rob, I did check the NIC speed and Widows states that it's connecting at 1Gig and the switch also states that too. I'll check the Dell site for a driver update, but I do recall looking in Device Manager for a different device, and do not recall any issues pertaining to the NIC. MIKE

ok, it's connected at the right speed, at least. Definately see if there is an updated driver for the nic, it might well solve the problem. Suppliers are notorious for suppling old drivers with their systems.

I agree with Rob that updating NIC driver first. You can also try reinstalling the network card driver: Reinstall driver==============1. Click the Start Button, type "devmgmt.msc" (without quotation marks) in the Start Search box and press Enter.2. Double click to expand "Network adaptors".3. Right click your network card and click Uninstall.4. Check "Delete driver software for this device" check box, click OK.5. Restart the computer and reinstall the driver. Vivian Xing - MSFT

Just got around to it, but the drivers were up to date on the Dell PC's. I downloaded the latest anyway, and installed, but no difference with the transfer speed.

Hi,Did you try the "reinstall driver" step?Vivian Xing - MSFT

I did, it stated that the most current driver is already loaded. I found a link on the HP site stating that if KB958644 is installed, may cause problems with file transfer speeds. I need to pop in to his place and give that a try. Thanks....Mike

So I found a solution. I found this doc, http://social.technet.microsoft.com/Forums/en/itprovistanetworking/thread/2a5e2868-ae70-4ad5-a2f1-2291f9b22b5b and it gave me the idea to disable the Large Send Offload (IPv4), Large Send Offload v2 (IPv4), and Large Send Offload (IPv6) under the Advance tab when you configure the nic. This fixed my problem and all is working well.
