SYMPTOMS
Consider the following scenario. You install Windows Services for UNIX on a Microsoft Windows Server 2003 R2-based computer on which &quot;Client for NFS&quot; is running. Additionally, you have a Tru64 UNIX-based NFS server. In this scenario, when you try to mount a network file system (NFS) export on the NFS client computer from the NFS server, you receive the following error message:

Network Path Not Found.



CAUSE
This problem occurs because of an error in the Domain Name System (DNS) reverse lookup.



RESOLUTION
Create pointer (PTR) records for the NFS client computers on the DNS server.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
In this scenario, the NFS client computer can enumerate the NFS export. However, the NFS client computer cannot mount the NFS export. If you capture a network trace when the problem occurs, the trace includes the following information:

&quot;V3 MNT Reply&quot; Reply State: denied (1) Reject State: AUTH_ERROR (1)

Some NFS servers require valid PTR records as part of the security mechanism.
