When we scan a NFS share using Network Discover it fails with the message an access denied message. The scan detail logs collected from the Network Discover server we can see the following:
[SEVERE] (DISCOVER.103) Incorrect Username/Password "domain\username" for share specified: "\10.x.x.x\vol\share_target_name"
[INFO] (DISCOVER.122) Failed to open content root nfs:"//10.x.x.x/vol/share_target_name", reason Access is denied.
Release: 15.7
Component: Default-Sym
The NFS share is configured to use anonymous access.
In the Enforce console navigate to the Scan Target -> Scanned Content tab
Then select the "Use These Credentials:" button and remove all information present so the fields Name, Password and Confirm Password are left blank.
Save the Scan Target and run the scan again.
You should now see the scan running successfully now.
For NFS it is a best practice to add the exclude filter to avoid scanning the .snapshot.
You can find more information and examples on configuring the scan target in the online help:
