Why does one of my users have slow SMB file transfers and browsing, but all other networking is fast?

I have a single user in a Windows 2003/XP domain who is experiencing excruciatingly slow file access to local servers across the network. Email, ERP applications, Citrix sessions, web, and network printing all behave normally. The only things affected are browsing network shares and accessing or executing files from the network.

Case in point, I started the user upgrading his UPS software from the deployment folder on the server. It took 90 minutes for the installer to initialize, and the next 5 hours for the installation to reach 32% completion. At this rate, he'll be done sometime Thursday night.

All our computers relatively the same in terms of OS, patching, hardware, and application loadout. So I'm thinking this is some sort of configurational error. I'd greatly appreciate any troubleshooting tips or solutions.

i had a similar problem on a server that had a "toe" adapter. i had to physically remove it. since this is a workstation it probably isn't the exact same issue...but it could be similar. like uescomp said, replace the drivers or if possible disable the adapter and install a new lan adapter.

Can you post an IPconfig /all from that client machine?

Reinstalling the NIC driver did it. I've done that before for other connectivity issues, but it was always a complete failure issue, never something as granular as SMB file transfer. Now I wonder what happened to cause it.

Thanks for reminding me to do the simple stuff even if it doesn't seem necessary. :)
