CMD:server(playerid, params[])
{
    if(IsPlayerAdmin(playerid)) return 0;
    if(isnull(params)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /server <new name OR just gmx>");
    if(!strcmp(params, "gmx")) return SendClientMessageToAll(COLOR_WHITE, "Server restart!"), SendRconCommand("gmx");
    else
    {
        new str[128];
        format(str, 128, "The server name's been changed to: %s", params[0]); //Try params[0] instead of params?
        SendClientMessageToAll(COLOR_RED, str);
        format(str, 128, "hostname %s", params[0]);
        SendRconCommand(str);

Forgot it, I wanted to test it (you must test a code before posting it), but I must reinstall GTA San Andreas: It's not working. Sorry, I couldn't test it yet. However, if you do:

/server gmx
It will restart the server (Atleast, it should do that )

/server {any_other_name}
It will change the server's name to {any_other_name} and send to everyone a message.

/server Kwarde
It will change the server's name to Kwarde
