    I setup Server 2003 for a small site and they are having major
    performance problems browsing the shared filesystem, where opening a
    folder might take as long as several minutes. During this time,
    explorer goes non-responsive and they just have to wait it out or kill
    the process.

    This only happens over the network -- local browsing of the filesystem
    from the server's console is lickity-split fast.

    My first guesses were all the obvious places (duplex and speed
    mismatches, name lookup errors, etc). Doing some traces, however, the
    thing I noticed is that the CPU pegs at 100% utilization whenever
    somebody starts opening folders, and this appears to be the culprit
    entirely. The CPU does not peg when the same filesystem is accessed
    locally, and there are no other obvious errors in the network
    configuration.

    The CPU shows the big hogs as lsass.exe and dfssvc.exe. Something is
    amiss here, and I'm not really sure what it is, since I'm not entirely
    sure what these things do and how they could be causing so much
    difficulty for network clients only. Any advice appreciated.

    Thanks!
