This evening I tried to rdp into my server 2008 box and was unable to. After poking around some I discovered that something is awry with my Windows Firewall. I did install 5 windows updates remotely earlier today but rolled those back in an attempt to see if that fixed the problem but had no luck.
Symptoms:
cannot rdp to machine (including from itself)
cannot ping machine
cannot connect to file share on machine
error message when attempting to open "windows firewall with advanced security" snap-in (there was an error opening the windows firewall with advanced security snap-in ... The Windows Firewall with Advanced Security snap-in failed to load. Restart the windows firewall service on the computer that you are managing. Error code: 0x6D9.
When I opened the "user-friendly" Windows Firewall it failed to load most of the gui elements, meaning, the title bar with close, minimize, and maximize buttons is present, the rest of the window has a white background with a yellow rectangle with rounded corners and a yellow triangle w/ an exclamation point is in the upper right. hope that made sense
"Windows Firewall" does not appear in the list of services
I ran a virus scan that found nothing.
How do I fix the firewall and hopefully restore the ability to rdp?
EDIT: Added at fission's request:

Those two registry keys do exist: HKLM\SYSTEM\CurrentControlSet\Services\mpsdrv & HKLM\SYSTEM\CurrentControlSet\Services\MpsSvc
! The problem seems to be with the Base Filtering Engine, when I try to start it I get the following error:
Windows could not start the Base Filtering Engine service on MYCOMPUTER.
Error 15100: The resource loader failed to find MUI file.
EDIT2: I ran sfc /scannow and i found about 100 occurrences of "[SR] Cannot repair member file"... including several related to the firewall (ex: [l:32{16}]"Firewall.cpl.mui" of Networking-MPSSVC.Resources...). One of them mentioned wordpad.exe, which I tried to open, and it failed. I found here mentions of mounting the install.wim on the install media to copy the affected files over. I am downloading the appropriate AIK and will continue tomorrow evening.
