Thanks for your response and kind attention to this matter.

I don't know for sure how that antislash got in there.  I think I was using two 
lines and it was on the end of one line and it got wrapped.  It just quotes the 
next character anyway.  I tried it without it and I still get the same results.

I looked over http://superuser.com/questions/430163/cifs-share-mount-errors and 
nothing helps there.  On this same Debian box, I run a Windows 7 virtual 
machine, and it can access the DFS shares just fine.  The Windows VM is on the 
same subnet, going through the same routers, etc. as the host Debian box.

I will add that sometimes I get

mount error(115): Operation now in progress

and sometimes

mount error(5): Input/output error

I can issue the same command over and over and I can't find any pattern to 
these messages.

I have also looked at the network traffic and although I don't understand much 
about what is going on, here is one thing is see that might help.

After the session is set up, the Debian box sends a GET_DFS_REFERRAL for 
\internal.compu-share.com\data.  The DFS server sends back two referrals, 
\CSI00-DC1\Data and \CSI00-DC2\Data.  These are two Windows servers that offer 
this DFS volume.  The very next packet that Debian box sends is a Logoff AndX 
Request, the server sends a Logoff AndX Reponse, and then the Debian box closes 
the TCP session with a FIN packet.  I think it should follow these referrals 
until it gets to the actual device that is offering the service.

You have an antislash (\) before user. Can you double-check?

Bug#801624: cifs-utils: mounting Windows DFS shares fail

[Jimmy Crossley]

Package: cifs-utils
Version: 2:6.4-1
Severity: normal

Dear Maintainer,

Mounting a Windows DFS (Distributed File System) fails with "mount error(115):
Operation now in progress"

sudo mount -t cifs //internal.compu-share.com/data/ /mnt/data -o
noserverino,\user=jcrossley,pass=$PASSWORD,domain=compu-share,sec=ntlm
mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Using the actual name of the file server instead of the DFS name works.

In this example, the DNS entry for internal.compu-share.com points to three
Windows Servers, which have referrals to the actual server.  The server is a
NetApp.  It appears as though the client is not following the referral.
