pawn Code:

public ChangeTimer()
{
    SendRconCommand("hostname **THE HOST NAME U WANT HERE**");
}

public OnGameModeInit()
{
    SetTimer("ChangeTimer",1000,1);
    return 1;
}

Since I don't know your code you can just set up a timer that will change the server hostname each 1 second to the one you want incase the host name changes to the other after one second it will change to your own.

I hope this helps.
