A specific user has a Dell Optiplex 745 using Windows XP with all the updates and service packs. I also have a Novell network client (4.91, sp5) and Symantc 10 on there. I have updated the PC, checked it for spyware, viruses, etc and when I am at the PC is is moving fast with the internet and opening apps. After I leave the user complains of internet slowness and IP conflict messages. Does this sound like a possible network card problem? Any thoughts? It's been going on a month and I keep checking it out and it all looks fine. I have even logged in and worked at this PC (as the user) and it seems fine.
