SYMPTOMS
When you attempt to resolve a NetBIOS server name that is longer than 16 characters (for example, net view \\ ) after you establish a virtual private network (VPN) or Remote Access Service (RAS) connection, the following error message may be displayed:

System error 53 has occurred.

In addition, programs that rely on resolution of NetBIOS server names that are longer than 16 characters may be unable to contact the server and error messages similar to the following examples may be displayed:

Server not found.

Server unavailable.



CAUSE
This behavior occurs because the service responsible for directing the resolution of NetBIOS server names longer than 16 characters was not informed of the creation of the transient registry key that contained the new DNS server's Internet Protocol (IP) address.
