    Question Unanswered: Error: ConnectionCheckForData (CheckforData()).

    Here is the error message that I am getting:
    Quote Originally Posted by Error Message

    Server: Msg 11, Level 16, State 1, Line 0
    General network error. Check your network documentation.
    The situation is this:
    Client: Microsoft Windows 2003 Standard
    Client s/w: Microsoft SQL Server 2000 Client Tools (patched with SP4)

    Server: Microsoft Windows 2003 Standard (SP1)
    Server s/w: MSDE 2000, SP3

    Connection is made over a MAN through two firewalls.

    Error conditions:
    1. I am able to make the initial connection.
    2. I am able to perform:
    b. SELECT Host_Name()
    c. SELECT TOP 1 * FROM sysfiles
    3. I get the error whenever I attempt to perform any multi-row recordset (such as SELECT TOP 2 * FROM sysfiles).

    We have restarted the SQL instance and the error repeated itself immediately.

    When we restart the server, the error goes away. Right now, I am trying to figure out how long from the time the server is restarted to the time the failures appear. By the way, the server is not mine; it's managed by a partner agency so I have limited access to system statistical functions. I have tried inspecting @@PACK_SENT, @@PACK_RECEIVED and @@PACKET_ERRORS, but I do not have access to sysperfinfo or perf monitor.

    I have tried Googling the error message and the results seem to be scattered: there was a problem with corrupt indexes (fixed in SP4), a problem with distributed inserts and some other issues that don't seem to apply in this situation.

    I am mystified and I don't know what to suggest. If any of you have any ideas, I would be grateful for your thoughts.

    Thumbs up

    Check ur networking hardware or configuration
    somewhere. Look at your network interface settings - especially duplex
    settings. Sometimes setting the NICs to Auto duples causes these errors.

    checked SQL Server error log? Stack dumps?
    I love cursor,though I never use it.Cos' I dont want to misuse it.
