Nfs – unable to access NFS share(s)

nfs

Unable to access NFS shares on Ubuntu from Windows 7. It just acts like the share can't be found on network. (NET HELP MSG 1222)

on client:
added NFS features
tried "mount IP:/share z:" and the gui drive mapping
tried with and without "AnonymousUid""AnonymousGid" DWORDs under HKLM\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default
firewalls are off

on server:
exportfs lists the shares.
mount shows "nfsd on /proc/fs/nfsd type nfsd (rw)" (I think that's normal?!?) have experimented with many options in:
/etc/exports
/etc/default/nfs-kernel-server
/etc/default/nfs-common
tried forcing no NFS v 4 after each change I'm restarting nfs service and re-exporting

Is there a log I can look at somewhere?!? I've been trying to figure this out forever… Any help would be much appreciated!

I once ran into a problem connecting to NFS shares from Windows 7. For me, the solution was to do the following on my Windows machine:

  1. Open group policy editor (type “edit group policy” in the windows search bar)
  2. Expand the tree selection to Computer Configuration->Windows Settings->Security Settings->Local Policies
  3. Select the Security Options item
  4. Disable the policy named “Microsoft network client: Digitally sign communications (always)”
  5. Restart your computer
