If you are looking for a comprehensive list of all Active Directory ports and protocols, you are probably reading the right stuff! This article documents all that you need to know about the protocols and ports used by the Active Directory (AD) for AD authentication and AD replication.

Active Directory Protocols

AD replication process usually takes place between two or more domain controllers within the specific AD Domain or between the global catalog servers and the domain. The two major Active Directory protocols used in these processes include the SMTP (Simple mail Transfer Protocol) and the RPC (Remote Procedure Calls). The type of protocol used for the process depends entirely on the kind of data that needs to be replicated.

For instance, SMTP can be used for replication of Schema, Configuration, and Global Catalog data. However, replication of Domain Naming Context (DNC) data cannot take place using the SMTP. DNC data, therefore, requires RPC for its replication. Also, bear in mind that in case you wish to secure replication data across firewalls, you must have the plans for both SMTP and RPC data in ...
... place.

Active Directory Ports

Interestingly, AD replication has no defined port. Instead, the Remote Procedure Calls (RPC) actually occurs dynamically via the RPC Endpoint Mapper (RPCSS) using the available AD port - Port 135. The same is the case with the FRS (File Replication Services). Other significant Active Directory ports include TCP 139 (SMB), TCP 389 for LDAP, TCP 53 for DNS Download, TCP 42 for WINS, UDP 53 for DSN (DNS Queries), UDP 42- WINS, TCP 135 - MS-RPC, TCP 3389- RDP, TCP 1026 & 1025 for AD Login and Replication, TCP 445 for SMB, Microsoft-ds, TCP 639 for LDAP over SSL/TLS, UDP 88 for Kerberos v5, TCP 3268 (Global Catalog), UDP 137 & 138 for NetBIOS related, TCP 3268 for Global Catalog over SSL/TSL.

But, that is not all! There are several other ports that are used by the Active Directory for its authentication and replication processes. You can discuss all these ports and their functions on technical online forums that encourage discussion topics related to IT hardware and software. You can find many such forums online. You must just know which forum or portal is more reliable and informative. You can read several related articles, news, and latest updates on these portals. You can also post you doubts and get answers from others.
