I just spent about 6 hours setting up my server trying to get it all smoothed out and ready to go! My server info is as follows: C:\srcds\srcds.exe -console -autoupdate -game cstrike +maxplayers 12 +map de_dust -tickrate 100 +fps_max 600. I also have WMP running in background and I could join and at one time someone joined but I could not see my server in the master list. after about 30min of messing with options I changed the map on my server (changelevel de_dust2) and like magic my server was on the master list, as a test I closed down the server and restarted, when I was up and running again I looked in the master server list and once again it was nowhere to be found so I again changed the level and again it showed up! This is a great find and I dont know if anyone else has relized this or come accross this but I figured I would let everyone know and people to try this out! I run this server and play on the same machine and everything is flawless!
