Thread: Network Searching Delays File Opening in XP

    Network Searching Delays File Opening in XP

    It takes around 20 seconds for me to open a file -- jpg, txt, whatever by either doubleclicking or using the Open command with a right click. The problem goes away if I disable my networking hardware. In fact it becomes very fast.

    Here is some of my netstat -a output:

    I can't figure out how to find the offending function that is hanging, timing out, or whatever. Also, what the hell is my PC doing going to the DMV, Redwire, etc. when I try to open a file?!?!?!

    I'm not running Norton or Symantec virus junk.

    This is a 3.2 Ghz machine too!

    So, How does one determine which of the netstat entries is causing the problem, and how do you get rid of it?

    I've tried Googling, searching the registry, etc. Can't find anything there.

    Any ideas? Thanks in advance

    No antivirus product at all? ACK!
    Are you behind a NAT router, or plugged directly into the broadband modem with your PC on a public IP address?

    I probably wasn't clear enough. I read somewhere that Symantec's anti-virus might be the cause of the network delay, so I uninstalled it, tested to see if I still had the problem (I did), and reinstalled it.

    Has this computer ever been part of a LAN? What can happen is that if someone launches an application on a network share from this computer, and the application adds a context menu to windows explorer (like Winzip), every time you try to open a file windows explorer will try to find the application on the network share. If the computer that has the application is turned off or is no longer part of the network, windows explorer will time out after about 20 sec.

    Yes. It's part of my home network. How can I tell which application is being looked for every time I open a file?

    Should I just systematically start uninstalling applications until the problem goes away? That could kill a whole day.

    If you are comfortable using regedit it wont take long.

    Launch regedit and right-click on hive HKEY_CLASSES_ROOT and select find. In the 'find what' box enter \\ and click find. What you are looking for is the UNC (\\) path to the network share that hosts the application that is causing the problem. It will look something like this:

    \\\shareprogs\application\application.exe "%1"

    If you can't find anything in hive HKEY_CLASSES_ROOT then search HKEY_CURRENT_USER.

    Back it up before you delete it.

    I searched on \\ and got no hits,

    Then I searched on shareprogs just for the heck of it and also got no hits,

    These were searches in all the registry folders.

    The only thing that looked promising was some hits on, which is my LocalUserDHCP something or other, but I didn't want to delete that because it sounded legit.
