NET USE to 16 Character Dotted-DNS Name May Fail (221150)



The information in this article applies to:

  • Microsoft Windows NT Server 4.0
  • Microsoft Windows NT Workstation 4.0

This article was previously published under Q221150

SYMPTOMS

The NET USE command fails to connect to a server with a 16-character DNS name (such as xxxxx.xxxxxx.xxx).

CAUSE

NetBIOS names are limited to 16 characters. The last character is reserved for the system and is a special character used to identify the resource type. When connecting to a DNS-style name, the sixteenth character was being modified by the system instead of being passed to the DNS. DNS-style names should be passed "literally" to the domain name resolver to be resolved.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
