Yes, in properties of My Network Places, Advanced, Advanced Settings, I have already changed the provider order with Microsoft Windows Network on the top. But that not changed any affect during testing.

Since logging in as a domain administrator runs the kix script, then it is something other than Network Provider properties.

I have also updated to the latest client, but it has had no affect.

Since logging in as a domain administrator makes the login script work, I am thinking the answer may lie on security properties of the user account within AD. I am about to begin testing that.
