DFS Namespace issue

HI,

I have 4 namespace servers for my domain.  2 are Windows 2012R2 DCs and a 2003R2 DC in 1 AD site.  I have 1 other DFS namespace server Windows 2008R2 DC in another AD site. In the login script, i map y: drive to the DFS namespace.

Once a week, 1 person(in the ADsite with 3 DFS servers) can't access a folder in the Y:  A reboot 99% fixes it.

I have noticed if i wait a few minutes, the domain\dfs works, but i must remap the drive.

In windows explorer, if i do a domain\dfs, how doi know the actual server it is accessing...?

Thanks,

Tom...
