The development team has isolated issues in the initial Microsoft Deployment RC1 build. Toolkit was throwing errors when Configure ConfigMgr Integration, Configure Management Pack or Configure WDS PXE Filter features were invoked. The errors occur because two files were not properly signed in the Microsoft Deployment RC1 release. We have released an updated build which contains these signed files. Please download the latest installers from Connect web site.
If you would like to work around the issue without reinstalling Microsoft Deployment , you can refer to steps given at Microsoft Deployment team blog site.
Thank you for your patience and your diligence in testing Microsoft Deployment. Please make sure to submit bug reports on Connect Feedback site.
