If we apply the policy on Site level on (Microsoft.com) forest, it is going to effect on the users of the forest. Let’s see how this is done. Note: No GPO can be created but it can only be linked. Right Click GP Objects, create new Policy. Now that the GPO is created for ‘Removing Run Dialog from Start Menu’ let us try linking it to the Sites. Login as a Domain user (E.g. U1) and hit Ctrl + R you will be thrown with below error.

Secure communication paths that allow objects in one domain to be authenticated and accepted in other domain. Some trusts are automatically created.
Other trusts are manually created. Forest – to – Forest transitive trust relationships can be created in Windows Server 2003, 2008 and Windows 2012 Forests only. Trust Relationships Trust Category:
Domain A trusting on Domain B and, Domain B trusting on Domain C and, if Domain A automatically trusts Domain C then, it is called Transitive Trust. Domain A trusting on Domain B and, Domain B trusting on Domain C and, if Domain A does not automatically trusts Domain C then, it is called Non - Transitive Trust. Trust Directions: One way incoming – MICROSOFT users can login in HDFC domain but, HDFC user cannot login into MICROSOFT domain.
One way outgoing – HDFC users can login in MICROSOFT domain but, MICROSOFT users cannot login into HDFC domain. Two ways – Both MICROSOFT and HDFC users can login from either of these domains. Trust Types: Default – Two ways trust, Kerberos trusts (Intra Forest) Shortcut – One or Two way transitive Kerberos trust (Intra Forest) reduces authentication requests. External – One way non-transitive NTLM trust used to connect to/from Windows NT or external Windows Server 2000 domains. They are manually created. Forest – One or Two way transitive Kerberos trust. Only between Windows Server 2003, 2008 and 2012 Forest roots. Creates transitive domain relationships. Realm Trust – One or two way non-transitive Kerberos trusts connect to/from UNIX Kerberos realms. Group Policy modeling is a great security tool for troubleshooting Group Policy settings and testing GPOs before they are applied with Windows Server 2008.
When a user logs in, Windows combines all of the different Group Policies that apply to the user account with those that apply to the computer that the user is logging in from. While this might not sound so bad at first, each level of the Group Policy hierarchy contains many of the same settings. That means there is a potential for the administrative staff to implement contradictory Group Policy settings. In smaller companies, administrators might be able to avoid Group Policy contradictions by using a single GPO, but this usually isn't practical in larger organizations. The problem isn't really the contradictory settings themselves. Windows uses a set of rules to determine which policy setting takes precedence in the event of a contradiction. What can be a problem is figuring out what the effective policy is going to be once all of the various GPOs are combined and you're dealing with the contradictions. I have personally run into situations in which completely unexpected Group Policy settings were being applied, and figuring out where those settings came from was a real challenge because of the complexity of the Group Policy structure being used. Fortunately, you no longer have to troubleshoot Group Policy settings manually. Instead, you can use a technique called Group Policy Object modeling to troubleshoot your settings quickly and easily. More importantly, though, you can use this technique to test Group Policy settings before they are applied. That way, you know that the settings you are about to implement will have the intended effect.
