Slow Network File copy after XP SP2 Upgrade
I have a computer with an on board Intel 1000/PRO MT NIC. When I upgrade my
machine to Windows XP SP2 my network performance becomes very poor. Example: copy a 5MB file across the network (switched 100MB network) to a file server takes 40-60 seconds. Uninstall SP2, and performance goes back to normal (file copy takes place almost immediately). What makes this really strange is the problem is only one way. Only when I copy from the problem machine out to another. When I go to another machine and copy to the problem machine, the copy takes place almost immediately! I don't believe this issue to be related to the network. I have a notebook computer running WinXP SP2 as well, if I plug it into the same switch using the same cable, it works fine. Other settings tried to fix issue... - AntiVirus on/off doesn't change performance. - XP firewall on/off doesn't change performance. - Tried latest NIC drivers from Intel (ver 9.1 from 10/2004) doesn't change performance. - Tried several config changes on NIC (full duplex, half duplex, etc...) with no positive change in performance. - I even wiped the PC and installed Windows XP w/SP2 from scratch, the problem still exists. This problem has been driving me nuts for several weeks. Any help is greatly appreciated. Thanks! |

Microsoft offers free telephone support for Service Pack 2 (see http://www.michna.com/kb/WxSP2.htm for some more details). Whether they can solve your problem, I don't know, but it may be worth a try, given that you've pretty much traced the cause back to SP2. The only other thing I would try is to disable the on-board network adapter and install a different one from a different manufacturer, at least for a test. Hans-Georg -- No mail, please. |
