Windows Server 2008 R2 introduced additional security features which require additional configuration before WLab can communicate with the Hyper-V server:
- Make sure that Windows Firewall with Advanced Security has the rules for COM+ Network Access and COM+ Remote Administration enabled. They will be disabled by default.
- You will need to change the permissions on the registry key HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}. First, change the owner of the registry key to your own user login; this will allow you to make changes to the permission of the key. Then, modify the read/write permissions on the key, and ensure that the user that your Tomcat server runs as has Full Control.
