Password protected folders (with runas command)

[banan2]

Hello.

I've been working on a method to password protect files on my network, even after I've logged in with username and password.

This is how I do it:

1. I create a user with username "otheruser" in Active Directory on my server.

2. I make a shared folder on my server called "securefolder".

3. I remove all users from the NTFS rights on the folder "securefolder" and I add the user "otheruser" to the list. That makes "otheruser" the only user with rights to the folder.

4. I make a shortcut, with the following path:

runas /user:mydomain\otheruser "explorer.exe \\server1\share\securefolder"

In theory it should try to open that folder with the user "otheruser", and request the password for the user "otheruser". If the password is correct, it should open the folder, if not it should not open the folder.

When I click the shortcut, it asks me for the password, and I enter the right password, but I get another error:

RUNAS ERROR: Unable to run - explorer.exe \\server1\share\securedfolder
1385: Logon failure: the user has not been granted the requested logon type at this computer

Does anyone know what the problem could be?
