Don't know your server OS, but
If you have config file in Unix format, windows version of srcds can't handle that file same way.
There is difference between Unix and Win "new line" characters.

So try copy any other cfg file than server.cfg from server, and rename copied file to server.cfg.
And copy your cvar settings example from here forum post than inside your old server.cfg

If that not help, re-check file is not server.cfg.txt
Edit file and convert file to ANSI format (notepad++)
With notepad++ you can also check is it unix format.

To test that cfg file work, add bottom of file
say "server.cfg"
echo "server.cfg"
Then execute file while you are in game, if you can't see server console.
Rcon exec server.cfg
sm_exec server.cfg
