Hi Rajesh,
I Can see in your message monitor Path is written as "\\ADMIN-PC\TaxInvoice" in your communication channel. Try to give it as "/ADMIN-PC/TaxInvoice" (use forward slashes instead of backward slashes). Make sure your NFS directory is mounted on your server for using it as NFS.
You can check path from your url also.
http://<domain:port>/<directory path> . You can get exact path and see your folders also.
Regards,
Rahul
