Problem:

Microsoft Windows Services for Unix 3.5 is installed on the server PC, and the NFS share has been mounted successfully. However, when you try to view (5) an NFS share, you get the error message:
 
Requested operation not allowed. Access problem.
 
When you press F1, you get the error code CPFA0B1.
 

Solution:

This is a security issue. The iSeries cannot properly log in to the mounted NFS share.
  1. On the PC hosting the NFS share, go to the Services menu.
  2. Ensure that the service Computer Browser is started.
