I am able to mount an NFS share from Linux but when I use Cygwin I get
a stranger error:
$ mount //<server>/<share> /tmp/test1
$ ls -lrt /tmp
ls: cannot access /tmp/test1: No such file or directory
total 0
d????????? ? ? ? ? ? test1
But when I run the following I get :
$ /usr/lib/csih/getVolInfo /tmp/test1
NtOpenFile(\??\UNC\<server>\<share>) failed, c00000be
Note : 0xC00000BE = STATUS_BAD_NETWORK_PATH
The mount happened but not properly.
It might be linked to Windows McAfee Firewalls.
I would guess this mailing list will readily know what is wrong

You've answered your own question.

Hi Andy,
in theory this is the wrong mailing list. The right one for this type
of question is cygwin AT cygwin DOT com. But see below.

As Ryan indicated it may be related to firewall settings, but let's take
a step back first.
- Accessing NFS shares does not work out of the box on Windows. You
have to install the NFS feature in Windows first:
Control Panel -> Programs and Features -> Turn Windows features on or off
-> Services for NFS
If the above doesn't exist on your machine, you're out of luck. Since
Windows 7 this feature is only available to Enterprise customers :(
- In an AD environment you also should make sure to have the required
authentication as a UNIX user with the right UID/GID. I urge you to
read https://cygwin.com/cygwin-ug-net/ntsec.html, especially
https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nfs and
https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch-posix
- In the administrative "Services for NFS" dialog, make sure to disable
the krb5 security flavors. I had a lot of trouble with them, but
there's a good chance I did something wrong, so take this with a grain
of salt.
- NFSv4 is not support. Export the shares with NFSv3.
- If you export a share on Unix/Linux like this (/etc/exports):
/foo/bar/baz ...
there won't be a //server/foo share! There won't be a //server/baz
share either. Rather you have to access the full path as in
//server/foo/bar/baz. And that sometimes fails for no good reason.
Therefore, ideally construct your server paths to be exported with a
single path component, e.g., symlink or bind mount /foo/bar/baz to
/baz and then export /baz.
HTH,
Corinna

Enabling the "Services for NFS" solved my problem - thank you very much Corinna.

Corinna
You solved this before for me:
*"- Accessing NFS shares does not work out of the box on Windows. You
have to install the NFS feature in Windows first: Control Panel ->
Programs and Features -> Turn Windows features on or off -> Services for
NFS"*
I updated to *Windows 10* and the seem to be broke again.
Is that possible?
Andy

This is the wrong list for this discussion but ...

You must have at least a Pro version.
