We strongly recommend trying <strong>nfsd_debug.exe</strong> first (using the Instructions below) to verify that you can start the daemon and mount/unmount an nfs share.

     <li>krb5p security with AES keys do not work against the linux server, as it does not support gss krb5 v2 tokens with rotated data.</li>
     <li>When recovering opens and locks outside of the server's grace period, client does not check whether the file has been modified by another client.</li>
     <li>If nfsd.exe is restarted while a drive is mapped, that drive needs to be remounted before further use.</li>

-    <li>The Windows DFS client interferes with some requests, indicated by long delays during operation. To disable the DFS client, use regedit.exe to navigate to HKLM\System\CurrentControlSet\Services\Mup, and add a REG_DWORD entry named 'DisableDfs' with a value of 1. See <a href="http://support.microsoft.com/kb/171386">http://support.microsoft.com/kb/171386</a> for more information.</li>
     <li>Extended attributes are supported with some limitations: a) the server must support <a href="https://tools.ietf.org/html/rfc5661#section-5.3" title="RFC 5661: 5.3. Named Attributes">NFS Named Attributes</a>, b) the order of listings cannot be guaranteed by NFS, and c) the EaSize field cannot be reported for directory queries of FileBothDirInformation, FileFullDirInfo, or FileIdFullDirInfo.</li>
