Event 1005 occurs on a Windows Server 2008-based computer that is running Server for NFS when there is an unmapped user in the advanced mapping list

Consider the following scenario:

• You have a Windows Server 2008-based computer that is running Server for Network File System (NFS).
• You configure the Server for NFS component to use a User Name Mapping (UNM) server that runs on a Windows Server 2003 R2-based computer.
• There is an unmapped user in the advanced mapping list.

In this scenario, when you start the NFS service, the following error is logged in the event log:

Log Name: System
Source: NfsServer
Date: Date & Time
Event ID: 1005
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: Computer Name
Description: Server for NFS could not obtain mapping information from User Name Mapping. Server for NFS will make another attempt after 30 minutes.

Note This problem does not occur when the Server for NFS component is running on a Windows Server 2003 R2-based computer.
