This article was previously published under Q175436

SYMPTOMS

If your Microsoft Windows NT Domain Name Service (DNS) server is configured to forward requests to a DNS server across a Point-to-Point Protocol (PPP) link and that link goes down, your DNS clients on your local area network (LAN) may receive an error message similar to the following when they attempt to resolve host names:

Bad IP address


NOTE: Your clients will still receive this error even after the PPP link is re-established.

CAUSE

When the PPP link goes down, your Microsoft DNS server cannot automatically rebind to the Remote Access Service (RAS) IP address.

RESOLUTION

To work around this issue, any time your PPP link goes down you will need to stop and restart the Microsoft DNS server service to rebind the service to its RAS IP address.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
