Starting an application on web server

Hi there, I am hosting a server running castle wolfenstein for a few friends of mine & want to make a web page to run on the same server that they can log in to to stop & start the game when they want. I have tried putting the following code in a web page - <? exec ('f:\wolf\wolfmp.exe +set dedicated 2 +map mp_beach +set sv_maxclients 8 ') ?> This creates a process on my server as of wolfmp.exe but I cannot see it on my lan & they can't see it over the web. I also don't get any visual output on the server of the wolfmp.exe starting up the game console. When I try& kill the process via taskmgr it says access is denied. Does anyone have any ideas? Thanks a lot, Nic.
