When you attempt to reinstall the NWLINK protocol on a computer running Windows NT, one of the following error messages may be displayed:
The registry service subkey already exists.
The registry subkey already exists.
CAUSE

HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\NwlnkIpx

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinSock\Parameters\
Transports value exists, make sure that NwlnkIpx and NwlnkSpx
strings are removed from that value declaration.
