NFS share - NtOpenFile() failed, c00000be

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
- 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
- NFSv4 is not support. Export the shares with NFSv3.
- If you export a share on Unix/Linux like this (/etc/exports):
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.
