Question : Clients not connecting to WSUS

I have installed WSUS 3.0 SP2 on a Server 2010 box with Exchange 2010. I have updated the GP to point to this new WSUS location and the clients are seeing this new address. The problem is that the clients are not actually connecting with WSUS. See attached results from the WSUS diagnostic tool indicating error hr=0x80190193. If I attempt to go to http://192.168.0.10:8530, I receive the message:
403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.
It seems that the error might be related to the security settings within IIS, but I am not familiar with the new IIS layout and am not sure what, if anything should be changed there.

Thanks

Answer : Clients not connecting to WSUS

I have identified the error. When setting up WSUS, I set it up to use port 8530 because another website was also set up on this box. I updated the Group Policy to include the port (http://192.168.0.10:8530) and everything is working great.
