    I have a strange problem, there are some long network delays when trying to
    access network resources (shared directories & printers). It does not occur
    all the time but randomly (they are getting more frequent).

    I have 7 Windows 2003 servers in the environment and the problem appears to
    be happening on any of them (although I only have 1 file and print server so
    it is show most of the time on that one but shared resources I use on other
    servers are also affected)

    When I go to open a network directory the system freezes for upto 40 seconds
    before displaying the list on files in the directory. I can see nothing
    which is caussing this but it is beginning to get annoying when users are
    navigating to open files. Also when I print there are delays showing the
    list of printers available.

    Has anyone experienced a similar issue? Are there any tools I can use to
    investigate what is causing this as I have no clue as wo what is causing
    this. I have captured the packets using etehreal but cannot see where there
    are any roblems, all I can see is excessive checksum errors but do not know
    where to look to find out what is causing these.

    Thanks for the prompt response. I have disabled Checksum Offloading on the
    client side but this has made little difference. I will disable it on the
    file server this evening and see if that makes a difference.

    Could this be caused by dodgy\faulty cabeling?

    Amending the network card has not resolved the problem, I still get delays
    when accessing network resouces. Thi sis very strange as it does not happen
    everytime a network resource is accessed only occaisionally, it's almost as
    through there is a broadcast which is stopping access to the resource.

    The server is an HP DL380 and I'm going to update the network drivers this
    evening to see if that makes any difference.
