How to set default SQL Timeout

I have an app that uses ADO connections, and when I run a particular
operation I get a SQL Timeout, but when I run the same operation with the
same executable on another client I don't get a timeout. A Profiler trace
confirms that the first query times out after 30 seconds (the default), and
the second client succeeds after about 40 seconds. Both clients are running
the same MDAC version.
I thought that the query timeout is set in the ADO command object, but this
behavior leads me to think otherwise. Is there a way to set the default
timeout value on a client?
Thanks,
TomWell, I've partially explained my own problem. The client that isn't timing
out is running on the server using the shared memory protocol LPC. When I
disable that and force the connection to use TCP/IP or named pipes, then I
get the SQL Timeout. So now my question is why is there a different timeout
value for TCP/IP and named pipe connections than there is for shared memory
connections?
