"net use" command against NFS shares is not supported under wow64

  • Artikel

Recently we have a problem with “net use” command on Windows server 2008:

We launched a command prompt from c:\windows\system32\, executed a net use command to NFS share (Unix NFS Share), after a few seconds it resulted in a mapped drive on Windows.

On the contrary, when a command prompt was launched from c:\windows\syswow64\ folder, net use command to UNIX NFS file share errors with exit code 53 “Network path not found”.

This turns out to be a known behavior as The NFS network provider dll (nfsnp.dll) is required for net.exe support for NFS. No 32-bit version of nfsnp.dll is shipped on 64-bit SKUs. 

“net use” command against NFS shares is not supported under wow64.
