    Since we moved to DFS we see reoccurring pattern which we have never
    experience before. We are 95% mobile clients environments meaning we almost
    do not use desktops, 95% of users are on laptops. As long they in LAN or VPN
    all works well but as soon a user is working offline strange thing happens,
    anytime a user opens windows explorer or MS office application and try to
    browse for a file on local C drive it takes good 5 minutes to fully open
    windows explorer, basically window will open but then we see flash light
    going back and forth for few minutes. This only happens when user is offline,
    I’m assuming it is because XP client is trying to access map network drives
    and takes long time to quit trying. I have never seen this before until we
    have switch to use DFS. Any Idea how to fix this? Other then disconnecting
    drives on log off, I tested it and if map network drives are not present in
    offline mode this problem doesn’t exist because XP client is not trying to
    access network drive since they are not there. Why this is not a solution?
    Could be if 100% people are shutting down or logging of while leaving office
    but they don’t most of them either hibernate or standby they laptops or
    simple disconnect from LAN and walk away, so we cannot guarantee that their
    map drives will be gone as they go offline.
    So again do you guys see this as well with remote folks and any idea how to
    fix this? I will also mention something that I think is related, I noticed
    one difference between using “old†way mapping vs. DFS, previously when XP
    client was disconnected from LAN in windows explorer under Type map network
    drive had status “Disconnected Network Drive†now since we moved to DFS it
    always regardless if connected or not Type is “Network Driveâ€.

    Yes, we have the same issue, but the only answer I've found thus far is to
    unmap drives on logoff. I am also very interested to know why Windows
    Explorer is trying to access the drives when the user has not clicked on them
    - they are merely exploring My Computer or a location on C: drive.

    I hope someome from Microsoft with an understanding of DFS client will post
    a useful reply.

    this is some how strange but I think we have solution, stop and change to
    manual startup "Windows Image Acquisition (WIA) service on all clients,
    problem goes away

    Its hard to see a relationship between WIA and DFS. What ever made you look at
    this as a solution.
