Unable to see Servers in Steam.

[Bushmaster84]

I am unable to see any servers in the Steam Menu or while in HL2DM.

Can anyone give me any ideas on why this would be happening?

Thank you. :afro:

You got a firewall? Is it off?

I had the same problem.

My ZoneAlarm firewall was stopping the connection and completely freezing my PC.
