Ok dealt with..
Go tomitunes, buy rcon for iPad.. Press ban, doesn't work. Waste £2.99
Go back to iTunes , buy a remote desktop app, remote into server on the smallest most annoying rdp programme I have used in my life..
Eventually get notepad ++ open and search for him, copy paste his guid, which took me 5 minutes to actually do across to bans list.
Then get idea to download dart onto the server, which would have been a hell of a lot easier...
Thanks c64, can you also say on the server that I am sorry for no notification on bringing server down, as I couldn't chat on the rcon tool
Thanks
