Hello,

Clients communicate with WSUS server over port 8530 by default. I want to confirm if you have customize the port number during setup.

And telnet is used to test if the port is blocked by firewall..

Hi,

The default port for WSUS 6 is 8530. So is 8350 a typo or a costomized port?

Can you telnet that port?
