# TCP/IP-32 NetBIOS over TCP/IP May Not Parse DNS Correctly

Article ID: 124918

Article Last Modified on 10/13/2003

APPLIES TO

- Microsoft TCP/IP for Windows for Workgroups 3.11
- Microsoft Windows for Workgroups 3.11

This article was previously published under Q124918

## SYMPTOMS

When you use a domain name service (DNS) to resolve NetBIOS names, failures occur if the name being resolved is an alias or "CNAME."

## CAUSE

VNBT.386 is not correctly parsing DNS responses that contain multiple answer sections. This can cause unexpected behavior as text in the second answer section may be interpreted as an IP address.

## STATUS

Microsoft has confirmed this to be a problem in TCP/IP-32 for Windows for
Workgroups versions 3.11 and 3.11a. This problem was corrected in TCP/IP-32
for Windows for Workgroups version 3.11b.
TCP/IP-32 for Windows for Workgroups version 3.11b is available on the
Windows NT 3.51 compact disc.
