What happens if you try to do the following:

     PING RMYSYS('nwssql01')

It should respond with:

     Verifying connection to host system nwssql01 at address x.x.x.x

Make sure that the address (x.x.x.x in the above example) is correct for 
the server you're connecting to.  Also, remember that you're using NFS not 
Windows networking.  SO make sure you're using the TCP/IP host name (from 
DNS or hosts table) not the Windows NetBIOS name.

NFS requires two-way communication.  Not only does the data need to be 
sent from your System i to the NFS server, but the NFS server has to be 
able to send data back.  Make sure that SXXXXXXX.DOMAINNAME.COM can be 
looked up from both your local system and the NFS server.

This is all basic TCP/IP setup, and has very little to do with NFS other 
than the fact that NFS runs over TCP/IP!

In order to create a share on a Windows computer, you have to do it from 
the server itself.  You can't use MKDIR to tell a computer to share 
something that it isn't already sharing!!

To tell the /QNTC filesystem to create an entry for the nwssql01 server, 
type the following command.  Do not add any additional share or directory 
names after the server name -- all you want to do is establish a link to 
the server:

    MKDIR ('/QNTC/nwssql01')

Now, you should be able to see any shares available on that server by 
typing:

    WRKLNK '/QNTC/nwssql01/*')

Assuming the 'AttachmentsReady' share is already there, you're good.  If 
not, you have to go to the nwssql01 server and add the share. Once the 
share has been added, you can create directories within the share if you 
like.

    MKDIR ('/QNTC/nwssql01/AttachmentsReady/MyDir')

But, for security reasons, the share itself ("AttachmentsReady" in this 
example) has to be created on the server side.  The share is referenced in 
a path name the same way a directory would be, but it's not quite the same 
thing as a normal directory.


Note that your message discusses two completely different network 
protocols (NFS and SMB) and I replied to both of them.  I hope that's not 
confusing!  The first part of the message (the part discussing the MOUNT 
command and DNS) is about NFS.  The remaining part (the part discussing 
QNTC and the MKDIR command) is about SMB.  The SMB part should work with 
NetBIOS names, but the NFS part will only work with TCP/IP names.
