to LocalSystem in the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan
After you do so, delete the following registry subkeys. These subkeys on a
Windows XP-based computer that does not have SP1installed can cause the
symptoms described earlier:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\25
