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.
