Trying to find a solution for why Windows Firewall service is missing from one of our Windows 7 machines. The end result is that inbound ports are blocked on the machine so I am unable to manage remotely. At one point we had a group policy that Disabled the windows firewall service but discovered that for some reason that actually blocks all inbound ports. The policy has been removed but on one particular machine, the Windows Firewall service is missing altogether. I tried importing the HKLM\SYSTEM\CurrentControlSet\services\MpsSvc key from another working machine but it did not help.
I've tried command prompts like net start sharedaccess but it errors out that the service is disabled. The only thing I could think of was a .vbs script to start the service but I don't think that would make it appear in the services snap in.
