ODBC Timeout expired error

Some of my clients cannot access an application, and it seems there is
a communication issue(?). The application server is a bit slow, the
database server (MS SQL Server 2000, SQL SP4) is brand new and fast.
Users that have the problem are behind a firewall that allows
everything from the client network to the server network. I have
configured the ODBC DSN, tested it, and the test succeeds. When
starting the application however, they get an error, [Microsoft][ODB
C
SQL Server Driver]Timeout expired. I have traced the startup, and the
log file is pasted below:

It seems that the SQLDriverConnectW is what generates the error, but I
am not a database administrator, nor developer, and knows nothing about
what it is or means.
The ODBC-driver (odbc32.dll) version on the machines that get this
error, is identical to those that don't.
Can anyone interpret this trace for me? What goes on, what is the
ODBC-driver (or anything else) complaining about? Would be highly
appreciated!
Bjorn Henrik Formo.Any luck on this issue. I am running into the same error. The ODBC test
connects fine but from my application I cannot.
