With this setup, I’m able to copy most files from the windows system to the share without a problem. However, if the file on windows has the ‘Read-Only’ attribute set, the copy fails with a permission denied error, and looking at the Wireshark trace I’m seeing an NFS3ERR_ACCES error. Is there something I can set in the NFS-Ganesha config file to resolve this issue?

Hmm, is it possible that the windows NFS client is creating the file, setting attributes to read-only on the destination file an then doing the writes which fail? Maybe, try NFSv4 and see if it works better!

I don't think there's a v4 client for Windows. Daniel

It’s definitely on the V3 CREATE call that throws the error. I’ve seen that there are V4 clients for Windows, but haven’t tried any of them yet – is there one you believe would work?

Jeff, Thanks for the response. I did see that thread previously, with the only difference being that the file isn't getting written out. Let me give that fix a try and see what happens.
