Drive letter refers to a location that is unavailable

Greetings,
I've not posted to this board before so please redirect me if I'm in the
wrong place.

I work in an environment of about 50 user computers and several
servers.We're migrating our users from Win2KSP4 to WinXPProSP2. Some of our
servers are 2000 and some are 2003. I can get more info about our network
but I'll have to get it from the LAN administrator - I'm the User Support
person for our company.

Since we've started the upgrade to XP on the user's laptops (we're phasing
out of desktops) we've been having a very difficult network issue.The
problem seems to be most apparent when a user on XP is connecting to a
server on Windows2003 Server. We have not been able to replicate the issue
from Win2K to WinServer2003 or from WinXP to WinServer2000. We've also
updated Symantec to the most recent version with no joy.

The problem is that we seem to be unable to access files and folders on
network drives at intermitent times. Double-clicking on a file or folder
will result in this error message:
"Drive_letter:\ refers to a location that is unavailable. It could be on a
hard drive on this computer, or on a network. Check to make sure that the
disk is properly inserted, or that you are connected to the Internet or your
network, and then try again. If it still cannot be located, the information
might have been moved to a different location."
We've checked into this error message and found this KB - You cannot open a
mapped offline-files drive during CSC synchronization in Windows XP:
http://support.microsoft.com/?kbid=840749
but the fix has not sovled our problem.

However, the KB listed above is not our problem. We're fully patched.

The problem occurs in Office documents (PowerPoint, Word, Excel) and can
appear when moving files around in Windows Explorer. Depending on how you
attempt to open/save a file and depending on which application you are
dealing with, you can receive these various messages (besides the one listed
above):
PowerPoint -> The path or filename for M:\data\.... is invalid. Please check
that the path and file name are correct.

Excel -> 'M:\data\...' could not be found. Check the spelling of the file
name, and verify that the file location is correct. If you are trying to
open the file from your list of most recently used files on the File menu,
make sure that the file has not been renamed, moved or deleted.

Word -> This file could not be found. Try one or more of the following: *
Check the spelling of the name of the document. * Try a different file name.
(M:\data\...)

Word -> The folder 'M:\data\...' isn't accessible. The folder may be located
in an unavailable location, protected with a password, or the filename
contains a / or \.

This is a big PITA. However, the thing that most concerns me is the
potential loss of data. At this point, we've had 5 instances of people who
have lost data due to this problem.
This only occurs in Word. The user goes to File|Save as or they choose
File|Close and then choose to save when prompted. At this point, the
computer loses its brain and thinks the file is no longer where it actually
is. They receive this message:
There is an unrecoverable disk error on file ~WRL003.tmp. The disk you are
working on has a media problem that prevents Word from using it. Try the
following: *Try formatting another disk. * Save the document to another
disk.
After you choose OK, there is a series of about 10 different messages that
pop up, all allowing you only to choose OK. At the end of this lengthy
transaction, Word closes down, your file is gone and you are left with a one
KB file that looks like this: ~My Document Title Here.doc. If you read the
message above you'll see that it is trying to save a TMP file. If you are in
Word and you choose Save and get this error, you can say OK and then change
the File of type from TMP to Doc and everything is fine. However, if it is
one of the two conditions above, your document is lost.

So, does any one have any experience with this problem? It is frustrating,
aggravating, irritating, etc. It is not reproducible so it's difficult to
troubleshoot. Unfortunately, it does continue to occur. I'll be glad to
answer any other questions or get more specific information to you if you
think you can help.

Thanks,
Jennifer Q

As a workaround until the problem is fixed, can you make the files available
offline? They would be locally cached and then synced with the server.

Can you get the documents back using the Office Recovery Tool when the error
occurs?

Can you ping the server from the laptop when the error occurs?
