Issue Regarding 401 error by web service

| Issue Regarding 401 error by web service |  Hi,
I am having web service with number of methods. We are using integrated
windows authentication for this web service. This service is working fine
with integrated windows authentication.
If I call this service after two minutes of idle time, for first request I
will get 401 error as below. But later subsequent requests are working fine.
This error is coming only, if web service is idle for more than 2 mins. This
behavior is happening only in some of the machines. I am feeling this as
strange behavior. Any ideas would be greatly appreciated.
System.ApplicationException:
URL=http://localhost/CAWSSSTap/VDistributionWebService.asmx
---> System.Net.WebException: The request failed with HTTP status 401:
Unauthorized.
