"Disconnected network drive"

    My XP machine has a virtual machine running Vista (under Virtual PC

    If I create a "Shared folder" to permanently map a drive letter to a
    drive on the host machine the drive is immediately listed in Windows
    Explorer as "Disconnected Network Drive". However Windows Explorer will
    list files in the drive and programmes such as Word or Notepad can
    usually access files on the drive. However it will not save them.
    (There is a certain amount of "flakiness" during this process;
    sometimes there will be error messages about Windows Explorer.)

    The user on the Vista machine has the same name and password as the
    host machine.
    Both the Vista machine and the host machine belong to the same
    The share on the host machine is set to "allow users to change files".

    On a virtual machine running XP with the same settings, the above
    problem does not occur; the user can open, change and save files.

    Thank you for any suggestions.

    As there has been no reply to my original post below, I would be
    grateful if someone who knows a lot more than I do about this product
    could advise me whether (i) the question is unanswerable because it
    doesn't occur for anybody else, (ii) I have not made it plain enough
    what the issue actually is, (iii) I should have spent more time with
    the help file or (iv) I should just wait some more time and some answer
    may be provided.

    I realise that there's no obligation on anybody to provide an answer to
    questions here, but the issue described is actually preventing me from
    going to the next stage in my use of Virtual PC and, unless my
    experience is unique, it seems an issue of fairly major significance.

    Grateful thanks for any comment or suggestions, as always.

    It's probably more like nobody has run into the exact situation, I
    know I haven't. This may be something to do with Vista itself, rather
    than a Virtual PC issue, but it's hard to tell.

    Hi Jim: I have been having the same diffculties on my Toshiba laptop running
    Vista, and man it is driving me crazy.

    I cant share any files or use my printer over my Linksys wireless network.
    I have been trying for days to find answer with no success.

    I feel for you brother

    Hi Bob,

    Thank for the comment. When you say that you haven't run into this
    problem does that mean you've been able to map drive letters to shared
    folders on the host from within a Vista vpc without any problems, or
    that you've never actually used this function?

    Since the next responder to my message seems to be having the same
    problem, I wonder if there is some kind of bug in the interaction
    between Vista and Virtual PC that would be worth reporting to
    Microsoft. Who would do that, or would it happen just as result of
    being discussed here?

    Thank for the comment. When you say that you haven't run into this
    It means I have been able to do it, but it's a function I don't use
    very often. (I map drives a lot, but not usually to the host.)

    Vista has a problem doing that on real hardware between some machines,
    so I guess I'm not all that surprised that it might fail. I know I
    had to lower the authentication level in Vista to get it to work at
    all with older operating systems, but XP should be able to handle it.
    The only way to get it reported for sure is to go through Microsoft
    Product Support Services. The trick is to get a reproducible problem
    to prove it's not just one setup.

    Other things you can try are to turn off any kind of simple file
    sharing under both XP and Vista (host and guest), make sure you have a
    common user ID and password, and turn off any NIC offloading features
    that might be enabled on the host, also make sure you have current
    drivers for the NIC on the host.

    I started recieving this message today - the Virtual PCs is running XP Pro
    SP2 (getting ready to install Vista). I had previously shared folders with
    the host C:drive and the exteranl hard drive, which houses the Virtual PCs -
    no prblem. I put in a new USB Flash drive to be used for ReadyBoost. I
    works as expected on the host PC as expected. When I try to set it as a
    shared folder, it was working as you said. I just went back to the PC, now
    all of a sudden it works and reports correctly???

    I'm going to install Vista later. I'll let you know what I see then.
