I have a user that loses all TCP/IP connectivity after less than 30 minutes. He was on Windows 98 and it happened a lot so we upgraded him to Windows Millenium and the problems went away. We recently upgraded the Client Access Service Pack and theproblems came back. I tried uninstalling the service pack but the problem persists. I have even uninstalled Client Access completely and removed all references to it in the registry that I could find. I have removed TCP/IP and added it again and the problem won't go away. I have also reinstalled Windows millenium over the top of the install with no help. Anybody have any ideas for fixing this?

Anytime TCP/IP issues persist on one machine where nothing seems to work I'll put in a new network adapter card and reconfigure all the TCP/IP settings. If you didn't already try this, a faulty NIC may be your problem.

Good luck!

A little more information would be helpful - Network Operating sys, any error message displayed, can he log back in after being disconnected? Is this on a laptop?

I would first suspect that there is dialup network program that disconnects the user after a certain ammount of time below a certain percentage of connection utilization. I have this setting on my laptop, but I have not had a problem with the ethernet connection. If you can get him logged on, look at the task manager (ctrl-alt-del) and note all the programs running, and look for something that does not match up to what is runniong in a machine that does not have this problem. Do an end task on any programs that differ and see if the connection remains. If that works you willneed to remove the offending program or it may continue to happen each time the computer is restarted.

All I had to do was replace the network card and now it has worked for several days with no problems

In some cases when we get some damage in the Registry even if we remove and reinstall the network components we get the same problem.
I would recommend:
Msconfig => Startup and unticked any Network or Internet related application.
Remove DUN and TCP/IP and reinstal them. Test again.
Same problem? Remove TCP/IP manually from the system. Check Microsoft KB to do this
No solution yet ..?? Install Windows in a new folder.
Good luck
