In a MS-Win 2008 SP2 I am trying to find the group CERTSVC_DCOM_ACCESS.
I followed this link Error in MS-CA request instructions but I can not seem to find that group.
Where it? Does it have a different name?
They made the name a little more friendly these days, which may be why you couldn't find it.
It's created as a local group, so look in the local users/groups management tools; if your CA is a DC it'll be a Domain Local group instead.
