No it does not sound good. May have to do a recovery.
Only other idea is if you had another server 2008R2 box to figure out the keystorkes
Hook up a kedyboard to yor dx
logon
windows key +r
powershell >enter
netsh advfirewall set allprofiles state off >enter
So blindly disable the firewall with powershell. I am not sure if that has to be done at an admin level/how to do that without right clciking. But that is the general idea
