Use Universal distribution groups in a multiple-domain environment. The membership of universal distribution groups is replicated to each global catalog server in each domain
A network that consists of multiple domains within the network environment are referred to as a "Forest". An example of this would be a domain named x.com & a domain named y.com that are joined together in a trust relationship to form a multiple domain network, or a "Forest".
A domain is a logical grouping of devices in a single name and can be administered as a group. Domains are assigned to companies or subdivisions within companies. A forest is a collection of domain trees. A forest could contain domains from multiple sites, such as a parent company maintaining control over several acquired companies with different domain names.
Forest root domain
two-way transitive for domain in the same forest

Each Domain in a active directory forest has a what kind trust relationship with every other domain in a forest?
The term 'domain' is too general to compare to the idea of a forest. A domain and the AD can be a part of a forest. This includes; domain controllers, child domains, domain functionality, replicators, directory service and so on. The concept of creating a forest was first introduced in the windows 2003 AD architecture. Suffice to say interoperability with server 2000 and NT (which do not recognize the forest) poses limitations and security issues. Hence four levels of functionality. Some are, in my opinion, basically unsound with regards to the security levels of a forest. A forest is not to be taken lightly. It requires much research and preparation. The term 'domain' applies across the board in a forest. Moreover, a forest relies on security. The PC you start the first installation of a forest will be considered the root and will hold the high level admins such as the enterprise and schema admins. Making forest trusts (only on root domain) facilitates communications between domains and ADs that share the same SPN (service principle name) which have to be resolved at a remote location in another forest. The configuration also requires IAS, Kerberos, UPN, SPD, SID namespaces .... What am I forgetting? Thinking about configuring the root forest on the first PC makes you dizzy with abbreviations acronyms, protocols, group security, etc ... Comprehensive research and planning are crucial. Managing forests and domain is hard enough as it is. I'd say this basic principle of security properties could be considered the largest difference between a 'forest' and a 'domain'.

The first is the parent domain, and everything after that is a child domain. So you might have something like. parent.local this would be the first domain of the parent domain child.parent.local is the second or child domain
forest
The administrator .he/she is part of administrators group and has all rights in the domain.The entreprise admin has all the rights on the forest/domain both are default groups.You can rename your administrator's name and make him part of this group.
