I've been trying to isolate a problem at one of our sites after installing
ZENworks 6.5 Agents. The machines having problems are Compaq EVO D310s
running Windows98 with the newest Netware client running IP-only. After
approximately an hour, the workstations will drop off the network. It is
very similar to what happens when the server kills a connection due to
watchdog timeouts, but that isn't what is happening in this case.

I've been through all the troubleshooting steps related to lost
connections, but everything checks out okay. The only thing that fixes the
problem is uninstalling the ZEN agents. Win98 machines (same hardware) at
this site running the v4.x agents don't exhibit the problem.

Any ideas?
