Hi. I have read all i can find on this issue and i have got no-where.
I started a UO server this morning and have come to Gametracker to claim the server. I have renamed the server appropriately at least 5 times. Then clicked Restart server. Waited, refreshed gametracker, tried again. Every time i do it i get the same message about renaming to GameTrackerClaimServer. When i go back to the config file it has reverted back to the Game servers name.
I read about a query port earlier, if i need to know that, i do not know where to find it (thought i would throw that in now).
Any help would be much appreciated. Going round in circles here.

OK! I have done it! I was under the impression i needed to change the name in server config, i just did that and i changed it in the Config cfg. That seems to have done the trick. I don't remember seeing that second config change being advised on the error message i received when initially trying to claim. Although it is so much more rewarding getting it done by your own venturing
