Writing to mapped drive while running as different user

Sandeep_BANG · 08-11-2009, 07:40 AM

Hi,

I am new to Windows. I have fair Linux knowledge.
I have this following requirement.

OS: Windows 2000

1) I will login as "administrator". I will be creating a mapped drive to map to some folder on another machine. Lets say I use "net use".

2) I have written another script/ program (in perl) which will just open a file on this mapped drive and write something to it. If file is not there, it will create it.

3) I have added a local user on this computer say "testuser".

4) Now I will be running this script as "testuser" using the runas command.
say like this "runas /user:sandeep-w2k3\testuser "perl test.pl".

it seems like the script seems to run. But I don't see anything being written to mapped drive. Neither the file is getting created.

How to solve this problem. Pls help...

Thanks in advance...

Sandeep

Welcome to TSF!

Mapped drives are mapped on a per user basis. When using RunAs, they will not be available to the Script unless you load the user's profile and the drive has already been mapped while logged into that user's account.
Even if you map the drive under the testuser account, and use the /profile switch, it may not work.
I tried this:
RunAs /profile /user:testuser "cmd /k"
A command prompt opens, and net use shows the drive I mapped while logged into the testuser account, but lists it as unavailable. Sometimes I can access it, sometimes not.

The best way would be to have the script map the drive, or access it using the UNC path. I don't know perl, so I can't help with that.
