FPNW Pass-Through Authentication from Trusted Domain Fails If PDC Down

• Microsoft Windows NT Server version 4.0
• Microsoft Services for NetWare version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

A hotfix was built that changes the functionality of how File and Print Services for NetWare (FPNW) clients running login scripts that contain IF MEMBER_OF statements work when run from FPNW servers participating in a master domain model and using pass-through authentication to validate group membership. This validation may fail if the primary domain controller (PDC) in the trusted domain is down.

Please see the following article in the Microsoft Knowledge Base to understand the functionality change of the hotfix referenced in this article that does not work properly when the PDC of the Trusted Domain is down:

ARTICLE-ID: Q150733
TITLE : FPNW Groups Not Recognized from Trusted Domain

CAUSE

The FPNW server queries the trusted domain's domain controller when doing pass-through authentication. The API that the FPNW server was calling only queried the primary domain controller. The FPNW server now makes an API call that queries any domain controller.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:

Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack

STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
