DB is 9.0.2.3439. Service runs fine on server. Client machines will
make connection to db for about 90 seconds and then lose connection.
Nothing in Event Viewer on either Server or Client Machines to
indicate issue and Firewalls are all turned off on both machines.

Has anyone ever seen anything like this? We can't see anything that
would cause it to lose this connection.

Server is Win 2008 R2, Clients are Win7 64-bit, this is not an unusual
configuration for us to support and we have not seen this before. Log
files look clean also.

Thanks,

Lisa
