  1. Dang. Looks like a hit or miss fix then. I'm still having luck with it so I'll keep working with this fix. The only other thing I did was run "netsh int ip reset" from the command prompt in an attempt to restore the registry entries for the IP stack. I visited a client with this problem after making my 2nd post on this topic and repeated the fixes with success again. I did find that one machine's adapter came back to life but only with IP connectivity. DNS wasn't working, but I could use nslookup to resolve things. Pinging various addresses worked.
  2. My edit button went missing so I'm making a reply to my first post. I tried to replicate this deletion manually to make sure my results were consistent and I wasn't giving a bad solution. I found on my virtual machine that if I delete tcpip.sys manually and try to repair the protocol with the quoted process, it does not get repaired completely (tcpip.sys did not get copied to \drivers and I don't know why). Found a fix to this by locating another copy of tcpip.sys on my system and then copying it to c:\windows\system32\drivers before rebooting after step 10. This extra step did not seem to be necessary for a system with the false positive. Anyway, in the event that the installation of the IPv4 protocol doesn't seem to work, copying a tcpip.sys file into the \drivers directory might help. The tcpip.sys file that I copied into c:\windows\system32\drivers to replace the deleted file was found at C:\Windows\winsxs\x86_microsoft-windows-tcpip-binaries_31bf3856ad364e35_6.1.7601.17603_none_b52f4dc5c4a121e0\tcpip.sys Also be sure to reboot, release, and renew after all the restorations are done.
  3. I've had success fixing broken machines with the following steps. Restoring the file did not work, nor did netsh: 1. Uninstall or disable Kaspersky. 2. Open Control Panel > Network and Sharing Center > Manage Network Connections *or* Change Adapter Settings 3. Right click an adapter and click "Properties" 4. Click "Install" 5. Select "Protocol" and click "Add" 6. Click "Have Disk" at the driver installation window (you probably will only see the Reliable Multicast Protocol driver when the window first opens) 7. Enter "C:\windows\inf" in the "Copy manufacturer's files from:" text box 8. Click "OK" 9. Select "Internet Protocol Version 4 (TCP/IPv4)" from the protocol list and click "OK" 10. The protocol will install 11. Close the Networking window and reboot the computer 12. Re-enable Kaspersky with the proper exclusions
