Comments
 
This error is caused by a router requesting a bad IP address. See ME170278 to find out more about this situation.
As per Microsoft: "The DUN credentials that are being used on the Windows 95 client are the same as a Demand Dial interface on the RRAS server. This causes the RRAS Server to force IP address negotiation with the RAS client as if it were a router". See ME176512 for more details.
