Network Drive Mapping Problems

Hello All,



Where I work we are having a peculiar problem with mapping one of our
network shares as a mounted drive. Before I go any further I will
give a little background info on our setup. We are running Windows
Server 2008 R2 on our servers which users connect to via Oracle's Sun
Ray Connector. Upon login we have a script that will use the current
users credentials to map 3 network drives: one for personal storage,
one for group storage, and one for software installations (small ones)
and links to installer packages that they are allowed to install on
their personal computers.



Recently we have been getting reports of the group storage space not
mapping at login and when we try and manually map said share we get
the following error:

Windows cannot access \\server\share

Check the spelling of the name. Otherwise, there might be a problem
with your network. To try to identify and resolve network problems,
click Diagnose.

Error code: 0x80070035

The network path was not found.



Now for some reason this problem occurs randomly across our 49 servers
that our users access and need this particular drive. For example,
one week we can logon and off of all the servers and see that the
problem is on server x, y, and z but the next week we logon to all of
the servers again (without a reboot on any of them) and only server e
will have the problem. Another observations that we made was that you
can ping the server the that hosts the drive and can even go to the
root of the shared folder by typing \\server\ into an explorer window
but once you try and double click on the shared folder it gives the
error above. A reboot seems to fix this problem but we don't want to
have to reboot our servers every time we see that one is having
troubles with this drive as some users run long simulations that can
take days at a time.


Thanks for any help that you can give. If you need more information
just let me know and I will see what I can do.
