Query timeout problems

Front End: Access 2000 Project (.adp)
Back End: SQL Server 2000

I have an application that keeps timing out. I have opened the
DataLink properties in the front end (File, Connection, Advanced tab)
and set the timeout to 999. But the connection still occasionally
times out.

Any ideas? Some of the SQL is pretty horrible (multiple sub-queries
etc.)

TIA

The timeout you changed is the connection timeout, so it won't affect
timeouts caused by long-running queries. Depending on what connection
library you're using (ODBC, ADO), you should be able to change the general
timeout value, but I have no idea how - perhaps an Access group might give
more help.

In ay event, if the timeouts occur during different queries, or the same
queries with different parameters, you'll probably have to try to identify
the problem queries more exactly - Profiler would be a good place to start.
