KEYWORDS:kberrmsg kbnetwork msnets win95kbfixlist

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows 95 
-------------------------------------------------------------------------------

IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, you should first make a backup copy of the
registry files (System.dat and User.dat). Both are hidden files in the
Windows folder.

SYMPTOMS
========

When you try to log in across a dial-on-demand router with a Windows 95 client,
domain validation may not work. When this occurs, you receive the following
error message:

   No domain controller is available to validate your session.
   You may not be able to gain access to some network resources.

CAUSE
=====

Windows 95 issues netlogon mailslots to the domain name to find a domain
controller for validation. Windows 95 issues a mailslot three times with a
default delay of three seconds for a response to each mailslot. If a response is
not received after three attempts (roughly nine seconds), validation fails and
the error message is displayed.

Validation may fail if the domain controllers are located across a dial-
on-demand router, the router is not connected when the client begins sending the
netlogon mailslots, and the router requires longer than nine seconds to connect.
The result of the router connection delay is that the mailslots time out and the
client displays the error message.

RESOLUTION
==========


STATUS
======

This problem no longer occurs in Windows 98. To resolve this problem, install
the current version of Windows. For information about the current version of
Windows, visit http://www.microsoft.com/windows.

MORE INFORMATION
================

Note that the problem described in this article can also occur if the router is
not available (offline). This can be verified by a Network Monitor trace. To
resolve this issue, bring the router back online.
