Unable to pick file from file server by using pub.client.http service.

We are using HTTP service in WM 6.1 to pick the file from the file server.
We are trying to connect from webMethods on UNIX platform to windows file server by using pub.client.http service. when we are running this service it is showing the following error message
Authorization required ( ISC.0064.9314) unauthorized

Please provide your precious inputs.

Thanks,
kambam.

You probably need to provide the credentials to access the HTTP server on the Windows box. Review the IS BIS Reference for the pub.client:http service for information on how to do this.
