VDA error : Unable to initialize component

At the end of the installation of VDA 5.6 or 7.0 initialization of VDA component is done. During this steps it try to configure firewall port and setup DDC communications. During this process it fails sometime with error "Unable to initialize component"


As per CTX133350  this can happen when " Virtual Machine was cloned from XenDesktop Pooled static catalog and difference disk is attached to it. Note: This configuration is not supported and Windows OS should be re-installed after removing the difference disk." But this was not the case for me, it was because of firewall communication. I tried different windows firewall setting finally I have to let all the profile configured with everything "ON" option in order to make this work. Everytime you change firewall option you must reboot and then restart the process
