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.
RESOLUTIONSTATUS
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.
