    I have seen DFS problems with Windows 7 when accessing a DFS root with multiple roots. Sometimes shares are not accessible anymore when using FQDN names and/or Netbios names (when the problom occurs which is around 1 time per day over 600 workstations, sometimes none work, sometimes one is working the other is not working). We used a work arrount to point directly to one of the root servers instead of the DFS root. This always works but you are not redundant anymore.

    We have issued this to Microsoft however no solution yet

    Hi there. We are a small organisation with 2 sites; these sites ar
    connected via a VPN through WatchGuard boxes. We run Windows 2003 R2 server
    and use DFS2 to create organisation wide access to data. This namespac
    contains about 5 shares which are then mapped using logon scripts to driv
    letters. This has worked fine for over 3 years using a majority of XP Pr
    clients and 3 Vista Business clients. However I have replaced some of th
    older systems with 6 new systems running Windows 7 Professional and it i
    these that are experiencing issues. The problem seems to be that staff usin
    these systems will suddenly say their system is running slow when accessin
    shares and what appears to have happened is that the PC has dropped the lin
    to the local (site) based server DFS root and has instead connected to th
    remote site's DFS root (indeed you can see this by looking in the new styl
    Windows Explorer at the properties of the mapped drive letter and choose th
    DFS tab). Indeed it would appear that these systems cannot even connect t
    the local DFS root at all - they cannot resolve the servers name to a vali
    IP address. So RUN -> \\server1\ produces nothing whereas \\10.0.0.x
    instantly shows the shares\printers hosted by that server
    Therefore I do not know whether this is a DFS issue, a DNS issue or somethin
    specific to Windows 7; all the PCs are DHCP based and seem to pick up al
    relevant DHCP provided information and, once re-booted, instantly work fine

    Has anyone any thoughts please
    with kind regards in advanc
