Changing Credentials for Shared Review Server in Adobe Acrobat Pro

I am trying to set up a shared review host.  I followed the directions below.

Hosting a Shared Review: An Alternative to Acrobat.com

I am now getting an error message saying

"Could not get new comments. Acrobat cannot access the network. Please verify your computer's network connection and try again"

I believe I may have used the wrong password, and I want to go back and fix it, but not sure if that is it.  How would I change the password for the server, so that I can continue to troubleshoot?

Thanks all.
