The tool listed in the other post is a great utility but it also helps to know what it's looking at. Check out this link, http://myvirtualcloud.net/?p=751, and feel free to browse around the site as Andre has some great information on troubleshooting PCOIP. Also you want to include the pcoip_server file in any of your logs as that is where you will find a bulk of the connection information.
Don't be afraid to open a ticket with http://www.teradici.com/ too. I have found that they have wonderful support and are willing to go the extra mile to get you working correctly
