The System Log contains the following two Service Control Manager event7003 errors:
The Remote Access NWLNKRIP service depends on the following nonexistent service: NWLNKIPX.

The SAP Agent service depends on the following nonexistent service: NWLNKIPX.
This problem occurs after you remove the NWLink IPX/SPX CompatibleTransport on a computer running Windows NT system that has the RASserver service installed, and at one time had the IPX protocol enabled forRAS dialin.
