    You should be able to narrow this down by executing the following query in
    query analyzer...

    select * from sysprocesses where spid > 50 and blocked > 0

    I would run this every few seconds over a minute period or when the server
    appears hung. If you get anything returned chances are this is an
    application issue. If so I would recommend the Microsoft Newsgroups they are
    pretty good at providing the information you will need further to track down
    the issue.

    Subject: Strange behaviour of MS SQL 2000

    At the moment I have no idea if this problem is caused by a DOS to our
    win2000 box or
    is only a bug triggered by some client application that connects to the sql
    server.

    However this is what it happens:
    - client applications connected to the sql server stop working giving a
    timeout runtime
    error or freeze if CommandTimeout property is set to 0 in the
    ADODB.Connection object
    of the client apps.
    - no other clients can connect to the sql server.

    It is possible to login from remote to the server via terminal service and
    all seems to be
    normal, sql server working, there is no strange disk activity, memory usage
    or other
    resource leaks.

    The only way to solve this block is to log in and log off on physical
    console! I'm getting
    crazy! How can be possible that services that run in background are
    influenced from an
    interactive login on console?

    I've made several analyses using a packet sniffer on the lan and doing sql
    traces
    running sql profiler and it seems to be all ok but never happend this
    problem during
    these analyses!

    Thank you in advance for any help.
