Samba: "mount error(115): Operation now in progress"

[PROBLEM]
While trying to mount a DFS Windows network-share (CIFS) on Ubuntu 12.04 LTS (precise pangolin), I get the following message:
mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
dmesg adds some "familiar" comments (see my other thread #1958:
[ 276.352021] CIFS VFS: Error connecting to socket. Aborting operation
[ 276.352104] CIFS VFS: cifs_mount failed w/return code = -115
Strangely though, the same mount works flawlessly on another machine with identical OS and config (PXE boot. So they are literally identical)...


[SOLUTION]
In my case, the DFS share was on a storage in a different subnet. I added a network alias (eth0:1) with an IP in that storage-subnet and then it worked.

I would have expected something like "no route to host" instead of the cryptic "error (115): Operation now in progress"...

Well, can't have it all ;)
