This has worked for some
1. Open the Windows Registry Editor (regedit.exe)
2. Go to HKEY_CURRENT_USER\Software\Microsoft\Microsoft Games\Links 2003\LinksTour
3. Double click on the Server key and change the value from server.lspn.net to
http://www.lspn.net ( you don't need the http:// start with www)
4. Close the Registry Editor
5. Start Links 2003 and you will be connected to the new server
