I'm getting the following error on Windows XP clients only:

[DBNETLIB][ConnectionWrite(WrapperWrite()).]General network error. Check
your network documentation.

This error seems to occur at random times of inactivity on my application.

Here is how I am configured:

Windows 2000 Server - Standard
Windows 2000 and Windows XP Pro Clients
SQL Server 2000
MDAC 2.7 or 2.8 on various clients

The error does not occur on Windows 2000 clients, only on Windows XP Pro
clients.

My application first opens a connection to a server database. Every 2
minutes an application watchdog timer triggers and attempts to write an
timestamp value to a data table. After some period of time (seemingly
random) the attempted write fails and I get the above error message,
followed by a "Connection failure." error.

Can anyone point me in the right direction on how to fix this problem?

Thanks,

Al Willis

Hi Al,
I would try to capture the problem using both SQL Profiler on the
backend, and network traces on the client machines.
General Network errors are commonly caused by tcp resets on the network.

Thanks,

Most probably problem with NIC drivers or network harware on specific
computers.
Also it will much help if you do not expect an open connection to stay
connected forever and make new connection after for each triggering of your
watchdog.

Kevin,

Thanks for the reply.

I looked at the SQL Profiler. What categories should I trace to find my
problem?

Hi Al,
You'll want to capture as much data about the clients and the
statements they're executing.
