Thanks @JuanS_OCS. I don't really have much to offer beyond my earlier points about the lack of a repository ACT suggesting the possibility of other issues, and that a review, ideally with the assistance of SAS Professional Service or a local SAS Partner, sounds like a good starting point. It is easy to add/configure a repository ACT again but the impact would most likely be significant (perhaps in a good way). If it were me, I would first want to spend a reasonable amount of time looking at the current setup to see if there are any indications of why it is like that. Was it a simple mistake or a deliberate decision? What will change if it were reinstated? Who would it impact, where, and are they all good outcomes? Discussions with any prior admins or consultants, if they are available, might provide clues too.
