Authenticate fails efter 2 min

I have written a WebService using .NET 1.1 that requires authentiction. The
client code (.NET service app) creates a proxy object, and sets
obj.PreAuthenticate = true, and
obj.Credentials = new NetworkCredential(<username>,<password> )

Then the object is used like:
if (obj.Check(id)) ....

This works perfectly in the lab, but on the production server, HP, Win 2003
server, it only works while the service is kept busy. After 2 min idle time,
the next call to obj.Check() fails with "Unauthorized" exception. Tracing
has verified that the credentials have not changed. Everything is the same,
just some timeout hits us.

Does anyone have a clue to this behavior?
