APPLIES TO


 * Microsoft TCP/IP for Windows for Workgroups 3.11

-



This article was previously published under Q120052





SYMPTOMS
Your computer running Windows for Workgroups version 3.11 with TCP/IP-32 network protocol stops responding (hangs) or drops back to MS-DOS when the 32-bit NetBIOS over TCP/IP (NBT) makes a query to the Domain Name Service (DNS).



CAUSE
The buffer allocated for the DNS name query in 32-bit NBT is one byte too short. The code that creates the DNS name query does not count the length byte of the domain name and allocates a buffer that is one byte short.



RESOLUTION
Microsoft has released a new file, VNBT.386, that corrects this problem.



STATUS
Microsoft has confirmed this to be a problem in TCP/IP-32. This problem has been corrected in an updated TCP/IP-32 version 3.11a. For information on the availability of TCP/IP-32 3.11a, see article 122544 in the Microsoft Knowledge Base.
