I have two computers set up like this:

  • \\myPC (local Windows 7 SP1 machine); it is in domain1;
  • \\remotePC (Win Server 2008 with SQL Server - a HyperV virtual machine); it is in domain2.

In domain2 active directory, I have a user account RemoteAccount. I would like to give this account full permissions to a shared folder located on \\myPC, i.e. folder \\myPC\SharedFolder.

The problem is, when I right-click the folder and go to sharing permissions, I can't add permissions for the domain2\RemoteAccount user, because this user cannot be found - I can only see domain1 users. When I click 'Locations' in "Select users, computers, service accounts, or groups" dialog, I only see domain1.

Is there a way to do this?

You need to create a trust between the two domains. At a minimum, a one-way trust where the domain that your computer is in must trust the other domain will need to be created.

This seems to be to the correct answer, but unfortunately it looks like I'm unable to create a trust - to do it, I'd have to be a domain1 administrator, which I'm not (I'm a local machine admin, but not a domain admin - and it fails to create a trust with these credentials). – w128 Nov 11 '13 at 10:23

The only other options I can think of

1) create a local user with the same user name and password on each machine 2) Grant permissions on the folder (first try granting the user, if that doesn't work, try users or authenticated users).

The right way is to have a trust like it's mentioned although is more involved.

I didn't downvote this, but I would be very careful about recommending that people blindly use Users or Authenticated Users in ACLs if you don't know their exact requirements. – MDMarra Nov 8 '13 at 16:26
This person could run process monitor and find out exactly what user and grant permissions on that user or create a group and add that user within the group. – Steve Schofield Nov 14 '13 at 2:25
