I probably have the weirdest situation you've seen in a long time. I've searched the forums here and have not been able to fix my issue.
I have a Mac running Leopard (10.5.1). I have a Windows Virtual Machine under Parallels Desktop for Mac (build 5160). The Virtual Machine is running Windows XP Pro with the current patches. I have ZoneAlarm Security Suite (7.0.337.000).
When I booted my Windows VM, I found out my copy of ZoneAlarm had expired. Everything works fine (except that it is expired). I can get out to the Internet. After uninstalling ZoneAlarm, I wind up with no Internet connectivity for the Windows VM. I've tried uninstalling the Network Adapter and having it reinstall on its own. No luck. I've uninstalled/reinstalled Parallels Tools (allows communication between the Mac and the Windows VM). No luck. I've removed the folders as described in other posts. No luck.
I've narrowed it down to the ZoneAlarm uninstall. I lose my connection right after rebooting from the uninstall. Prior to doing so, the machine works fine (even ran MS Update to get the latest patch set before uninstalling ZoneAlarm).
Anybody have any hints besides a complete reinstall? I've got a clone of my VM so I can get back to my last known working configuration. I can pop off another clone of that known good config to try things out.
Operating System:Windows XP Pro
