Windows Firewall disabled service blocking all

I've a Windows Server 2008 Standard Edition SP2 box doing something very
strange. We have Windows Firewall enabled via Group Policy but allows for
exceptions. With the firewall on we can rdp into box, but our sql port is
blocked.

If I disable the Firewall Service, we lose all communications to server. RDP
becomes instantly disabled and we still can't telnet the sql port.

I've never heared of having more items blocked by disabling the firewall. I
was hoping someone might have an idea what is happening.

Thanks.

I have never heard of a process that blocks RDP if the firewall is disabled.
If you have an established RDP session and you change the firewall on or
off, I have an idea it might drop the established session. If with the
firewall disabled you can't RDP at all then something else is wrong.
If you forget telnet and ports for a moment, can you communicate with the
SQL Server with the firewall off?

I had found a couple of different posts on the web experiencing the same
issue, but unfortuately I couldn't find any microsoft documents on the
topic. The issue they reporte was that you could turn off the firwall via
group policy or through the control panel, but if you disabled the actual
service via services.msc, etc. then all communication would stop.

Ah, OK. Yes, it should be controlled through Policy, scripting or GUI and
not by turning the service off.
