Can the CA enterprise role be installed on a DC with ADFS already installed , or will this cause problems?

You can add the CA role without any issues on any of the already installed roles in question. /Hasain

However this is not recommended configuration. You should not combine ADCS with other roles (especially with DCs).My weblog: http://en-us.sysadmins.lv PowerShell PKI Module: http://pspki.codeplex.com Windows PKI reference: on TechNet wiki

So combining DC ADFS and CA role is possible , those roles dont bite each other? Thanks Hasain again!

The recommendation about not combining the ADCS role with other roles in this case is mostly related to the restrictions that the ADCS role will apply to the server name and domain membership making it impossible to change any of the mentioned without uninstalling the ADCS role. /Hasain
