    I have just swapped laptops from a Dell with XP Home to a Dell with XP Pro.
    When I try to open MS Access Applications on a network share that I have
    written and which worked ok on XP Home laptop, I get the above warning and
    cannot open the application. If I go to the location where the files reside
    ie c:\docs & settings\all users\shared docs\ then I can open the files ok.
    Other files such as MS Word or Excel are ok but then they are not executeable.

    I have no Group Policy settings and at present and I am the sole
    administrator and user.

    I assume that the problem, is associated with the applications not being
    digitally signed,

    Can anyone offer any addvice on how to resolve this situation.

  2. Try using the IE security settings to define the machine from which
    the share is received as being part of the Intranet.

    Thanks for the response. That appears to be the culprit.
    It appears that any setting at IE7\Tools\I Options\Security\L Intranet above
    Medium-Low causes the situation I described. Setting the option at Medium-Low
    has solved the problem. As I use Mozilla across my network it should not be a
    security problem. However I do wonder why yet again an MS update/download can
    cause such a problem in a seemingly unassociated area. I would never have
    thought of looking in IE mainly as I never use it.

    Many thanks for your steer on the problem.

  4. I believe it was the IE 7 install, rather than any update, that
    caused this issue for you. The docs on changes to be expected
    with IE do discuss changes to the zone settings, but most people
    do not realize that the Internet Zones and their settings are used
    for more than just IE browsing actions.

    good stuff! using the info mentioned, it seems to have thwarted the use
    of *ULTRAREACH *(u94.exe or whatever it's been renamed to) on our
    network. the app is prevented from launching under Windows.

    many thanks
