Why is it not possible to map multiple network drives to the same share as different users from single machine without manipulating the share name? RRS feed

  • Question

  • I have a unusual case where I need to setup two mapped network drives as two different users to the same share location. When I attempt to map the second drive after inputting the user name and password the system goes on its merry way for a few seconds and then returns me back to the username/password input.

    If I change the second mapped network drive to use the IP address the two shares work happily. If I manipulate the host file and point two paths to the same address then I can also work around this problem. However, I would simply like to know why I am blocked from setting two mapped drives to point to the same share with different credentials? 

    e.g.

    TestFolder on TestServer is shared to TestUser1 & TestUser2 where the IP of TestServer is 192.168.0.2.

    Case1

    If I map S: to \\TestServer\TestFolder using TestUser1, if I then map T: to \\TestServer\TestFolder using TestUser2 it will not work. 

    Case2

    Mapping S: to \\TestServer\TestFolder using TestUser1, if I then map T: to \\192.168.0.2\TestFolder using TestUser2 it will work and I can access the folder as the two different users.

    Case 3

    If I map S: to \\TestServer\TestFolder using TestUser1, if I then map T: to \\TestServer\TestFolder using TestUser1 it will also work (but I am accessing S: & T: as the same user). 

    Why do cases 2 + 3 work, but case 1 does not?

  • Hi Tesmond,

    According to your description, it seems that there is a DNS resolve issue when User2 access to test server.

    Before going further, I'd like to ask the following questions:

    Is there a domain in your current environment ?

    When using testuser2, Could you ping Test Server name successful ?

    Best regards,

  • Hi,

    I am not sure you are understanding the nature of the question.

    Please create a test machine with 2 user accounts, share a folder on it, then on the same test machine try test case 2 mapping the drives (no domain or actual networking required). I believe you will easily replicate this issue on any windows 7 machine.

    I have not tested this on Windows 8+ but I suspect that the Windows credential manager has a bug which prevents it from handling a many to one relationship in respect to mapped network drives.
