Upgrade of SEP 11.0.7 to 12.1.2 kills network connection
I upgraded a computer from 11.0.7 to 12.1.2 yesterday. At the end, the installer requested a reboot. It booted back up fine. I shut it down at the end of the evening. Today I come in and the computer could not connect to any wired or wireless network. When I did a "ipconfig /renew", I got an error:
"The operation has failed as no adapter is in the state permissible for this operation."
I have since tried to remove SEP 12.1.2 but nothing has changed. Below is a summary of what I've tried so far:
Disabled Windows Firewall
- Removed antivirus (SEP 12.1.2)
- Removed nics, restarted, rediscovered nics
- Updated nic drivers
- Reset tcp/ip stack (see Microcoft KB 299357)
- Reset winsock (see Microsoft KB 811259)
- Reset winsock, ipv4, ipv6
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
When I run "netsh int ip dump", I see a mostly empty config with "reset" in the middle.
The network adapter is fine in Device Manager.
I've also looked for registry keys with "teefer" in them after seeing forum discussion https://www-secure.symantec.com/connect/forums/sep-1212-failed-upgrade-and-killed-network-connection
What's troubling is that the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetworkProvider key is missing completely. I don't know if that's from my "netsh int ip reset" attempt or something else more sinister.
Any advice is GREATLY appreciated. I cannot upgrade our users until I figure this out.
