 Last reviewed: March 26, 1997
Article ID: Q147799
The information in this article applies to:
  • Microsoft LAN Manager version 2.2c
  • Microsoft Windows NT Server versions 3.5 and 3.51
  • Microsoft Windows NT Server version 4.0

SUMMARY

When you attempt to log on to a Windows NT domain controller from a LAN Manager 2.2c client computer, an Error Net3779 appears.

CAUSE

This problem occurs if the computer name of the validating domain controller begins with an invalid character, even though the user name and password are valid. Computernames disallow the period (.), as well as the characters below:

ASCII characters 1 - 31 decimal, as well as the following: 

      .  "  /  \  [  ]  :  |  <  >  +  =  ;  ,  ?  *

RESOLUTION

Change the computername so that it does not begin with invalid characters.
