SYMPTOMS
When you use a Windows 95/98 Dial-Up Networking (DUN) client to dial a Windows NT Remote Access Service (RAS) server and you attempt to log on to a Windows NT domain, your logon scripts may not run and you may receive the following error message:

No domain server was available to validate your password.

You may not be able to gain access to some network resources.

In addition, when you attempt to gain access to a network share, you may receive the following error message:

Error 58: This operation cannot be performed by the specified server. Make sure that you have specified the correct computer name and command. If the problem persists, contact your network administrator.

CAUSE
This behavior occurs when both TCP/IP and the IPX/SPX compatible protocol are installed on a Windows 95/98 client, and both protocols are enabled for the dial-up connection. The IPX/SPX Netlogon requests may reach the primary domain controller (PDC) before the TCP/IP Netlogon requests.

RESOLUTION
To resolve this issue, "unbind" Client for Microsoft Networks from the IPX/SPX protocol on the Windows 95/98 client:


 * 1) Click Start, point to Settings, click Control Panel, and then double-click Network.
 * 2) Click the Configuration tab, click IPX/SPX Compatible Protocol -> Dial-Up Adapter, and then click Properties.
 * 3) Click the Bindings tab, and then clear the Client for Microsoft Networks check box.

MORE INFORMATION
When the PDC is configured for both TCP/IP and the IPX/SPX compatible protocol, the PDC responds only to the first Netlogon request it receives, regardless of other protocols configured on the server. Because the IPX/SPX Netlogon request arrives before the TCP/IP Netlogon request, the server responds with an IPX/SPX type 20 broadcast. By default, the RAS server does not forward IPX/SPX type 20 broadcast packets to the client unless two-way broadcasting of type 20 packets (NetBIOS over IPX) is enabled on the RAS server.

Because of additional bandwidth requirements, do not enable two-way broadcasting of IPX/SPX type 20 (14h) broadcast packets.

For additional information, please see the following article in the Microsoft Knowledge Base:

"Q173607 Client Not Authenticated by Domain Through RAS Member Server" Auditing successful logon and logoff attempts at the PDC shows the user successfully logged on, and a Network Monitor capture shows the IPX/SPX Netlogon requests arriving first.
