"server Not Responding"
...OK, so I'll admit I'm a bit of a newbie as far as running a dedicated server goes. However, I looked at Vadakill's guide and followed it and got one up and running on another PC in my house. I'm using the command line based HLDS, and run my server with a batch file. I've had several of my friends on it and had no problem with it. I stopped using it for a few weeks (2 or 3) and now tonight I tried running it again. My friend has the server stored in his favorites, but when he tried to join it said my server had a ping of 2000 and wasn't responding. Now, I was running around inside my server(from the computer I usually play on) and everything seemed fine. So my question is, why has it randomly stopped working and what can I do to fix it? (also, I ran hldsupdate tool again but that didn't help...)
