Environment : Forest A/Domain A have two-way transitive trust with Forest B/Domain B.
Forest A have some IIS/Sharepoints apps which needs site URL to be added to trusted site, works well as all are functioning as expected in Forest A as been pushed thru GPO to all computers in Forest A.
Forest B - User still log on to Forest B/domain B and use their Domain B credentials.
Issue - Users from Domain B when try to access to URL's (IIS and Sharepoint) hosted in Forest A/Domain A, are being promoted for credentials many times (Forest A/Domain A credentials) this works when you enter the credentials, to avoid this prompt we need to add URL's of IIS and Sharepoint to trusted site (GPO is already configured in Forest A/Domain A), do we have a term called "GPO Merge" the URL's are 200+ approx, we found the solution to add these 200+ URL's under Forest B/Domain B, what else can be done so User will not ask for prompt again and again.
Trusted site URL's on Forest A/Domain A has been added to "Computer Configuration ““> Administrative Tools ““> Windows Components““> Internet Explorer ““> Internet Control Panel ““> Security Page"
How can we achieve the goal till we have completely decommission one of the forest & domain and merge the computers in one domain?
