We have a site with some servers and users.
I need to decommission the only AD server on this site (others AD servers exist elsewhere along with FSMO roles).
Should I stop this server being a global catalog server first then dcpromo or just go for the straight DC promo?
Need to ensure that the other servers and clients continue to function fine as this site is almost in use 24 hours.
I would like to test the removal of this server first by downing the server for 12 - 24 hours, how would this affect users and servers onsite and can this be done safely in the day?
Looking forward to your comments :)
