Access to Samba\vfiler share via shortname

Question

I wasn't sure which section to post this under as it occurs on different
operating Systems (Windows XP SP3, WIndows 7, Windows 8, Server 2003, Server
2008) and is random.
Basically, some of our end users experience problems accessing shares to a
vfiler for example with shortname \\example\share.
They can access this specific share via ip address or fqdn
\\example.domain.local\share. The
user can even access \\example and be
able to
view shares there but when clicking on the share it comes back with network
error or access denied.
This does not happen to all users at a time and on the same
workstations\servers and there are no specific times. On the end users
workstation DNS and wins is working, they have
no problems accessing other
vfilers or F&P Windows shares.
I tried all flushing DNS and wins cache, tried rebuilding CSC (Offline files)
to no avail. We don't have this enabled in our environment in any case
but
gave it a try.
One way I got it working via shortname is by adding a new security group to
the security permissions on the share.  The group only had my account as a
member
and exsiting groups remained. After this the end user was able to map
via shortname.
I've tried many things and just can't figure this out or where to look. My
team doesn't manage the vfilers or samba shares so
can't look at the logs or
anything.
Another scenarion I have is for a Samba share, very similar situation but
this time its accessing the share on a Windows 2008 R2 server.
Basically
similar symptoms, can't access via shortname, get 'Network Error', tried several
things, even Windows Network Diagnostic
where it states that "The remote
device or resource won't accept the connection', "The device or resource (samba)
is not setup to accept connection
on port "The File and printer sharing
(SMB)". Port 139 is open, can access other shares on different storage devices
successfully.
What's weird is that after some time, An hour, 2 or 3 later functionality
returns without any changes. Obviously restarting the server resolved this
quicker.
There are no scheduled tasks or tasks running in the background,
Windows firewall is disabled, disabled AV etc.
I managed to get a log  from this Samba device but not sure if its
related or not.
[root@samba] [09:30:52]  /var/log/samba
# tail /var/adm/messages

Task exit with cims error: Error sending response: Broken pipe
Apr  3
09:10:07 samba adbindd[24524]: [ID 323999 auth.error] ERROR samba.adbindd2 Task
exit with cims error: Error sending response: Broken pipe
Only other thing I can think of is that is may have something to do with the
device, folder redirection, cache or something of that sort.
I'm stuck, anyone have any ideas. I would like to know what else to try if
the issue re-coccurs.

Hi,
I installed KB 2194664 and haven't had the problem since.

If it happens again I will revisit.
