Windows 2000 domain controller default port list
Suitable
summary
This document describes the most common ports, protocols, and services that run Active Directory-based Windows 2000 servers. The purpose of this article is to list different services and their respective ports rather than explaining how to configure a firewall or agent.
More information
21 / TCP (Transmission Control Protocol) - FTP
The File Transfer Protocol (FTP) server is part of the Internet Information Service (IIS), managed by IIS Administration. FTP is a common method for transmitting files and enabling users between two networking computers to facilitate use of remote file storage functions.
25 / TCP - SMTP
The Simple Mail Transfer Protocol (SMTP) service is managed by IIS Administration. SMTP is a protocol for sending email messages over the Internet. Miss 53 / TCP - DNS instructions
80 / TCP - HTTP
Hypertext Transfer Protocol (HTTP) is a set of rules for exchange files (eg, text, graphics images, sounds, videos, and other multimedia files) on the World Wide Web (WWW). HTTP is a program protocol compared to the Transmission Control Protocol / Internet Protocol (INTERNET SUP).
88 / UDP (User Data News Agreement) - Kerberos
The Kerberos protocol is a network authentication method based on a key distribution model. The protocol enables entities that communicate on the network to prove each other's identity, while the protocol can prevent eavesdropping or playback attacks. Kerberos Key Distribution Center (KDC) detects a ticket request on this port. The 88-port of the Kerberos protocol can also be TCP / UDP.
119 / TCP - NNTP
The Network News Transfer Protocol (NNTP) is the primary protocol for the manuscript used to manage the manuscript in the USENET newspaper. NNTP Server Manages the Global Network for the collection of UseNet newsgroups.
135 / TCP - RPC
Remote Process Call (RPC) is a tool that enables a Windows-based computer (client) to call another procedure running on a distributed network-based computer (server). RPC is a program level protocol that uses any communication services for any Windows network communication protocol (including TCP / IP).
137 / UDP - NetBIOS Name Server
Network Basic Input / Output System (NBNS) Name Server (NBNS) protocol is part of the NetBIOS (NetBT) protocol in TCP / IP, providing hostname and address mapping methods on a network based on NetBIOS name access.
138 / UDP - NetBIOS Data
The NetBIOS dataset is part of the NetBIOS (NetBT) protocol on TCP / IP, which is used in network login and browsing.
139 / TCP - NetBIOS Session Service
NetBIOS Session Service is part of the NetBIOS (NetBT) protocol family on TCP / IP, which is used for server message block (SMB), file sharing, and printing.
389 / UDP - LDAP
LDAP is a lightweight directory access protocol. LDAP is designed as a standard method for providing directory service access. In Windows 2000, LDAP is the main method of operating the Active Directory database.
443 / TCP - HTTPS
The Secure Hypertext Transfer Protocol (HTTPS) is a variant of HTTP, which is used to handle security transactions. HTTPS is the only security socket layer (SSL) protocol under HTTP.
445 / TCP - SMB
The SMB protocol is used for file sharing in Microsoft Windows NT and Windows 2000. Windows 2000 allows you to run SMB directly through TCP / IP, no additional NetBT layers. 464 / TCP - Kerberos password V5
Kerberos Change Password Protocol is used to reject administrators to set passwords for new users. This feature is useful in some environments, and this proposal can be used to enable password settings. Use this protocol when the user changes the password.
500 / TCP - Isakmp
Internet Security Association and Key Management Protocol (ISAKMP) or IKE (for Windows 2000) is a key exchange mechanism for virtual private network (VPN). The ISAKMP manages the exchange of encryption keys and uses two phases to establish Internet Protocol Security (IPSec) connections between the two gateways.
563 / TCP - SNEWS
SNEWS is safe NNTP.
593 / TCP - RPC on HTTP
RPC on HTTP is used for COM Internet services, you must have IIS, which can run.
636 / TCP - LDAP on SSL
After the SSL is enabled, the LDAP data sent and received will be encrypted.
1067 / TCP - Installation boot service
Install the boot protocol server.
1068 / TCP - Installation Guide Service
Install the boot protocol client.
1645 / UDP - IAS: Internet Authentication Service
This service is used to process remote authentication dial-up user services (RADIUS) authentication messages, IAS supports it to be compatible with early RADIUS servers.
1646 / UDP - IAS: Internet Authentication Service
This service is used to process the RADIUS billing message, and IAS supports it to be compatible with the early RADIUS server.
1701 / UDP - L2TP
Layer 2 Tunnel Protocol (L2TP) is a method of encapsulating standard point-to-point protocol (PPP) through various media package. The protocol also supports PPP through the UDP packet package.
1723 / UDP - PPTP
PPTP is an abbreviation for Point-To-Point Tunneling Protocol. It is an Internet protocol, usually used in VPN products. Windows NT supports PPTP servers, and Windows NT and Microsoft Windows 95 support PPTP clients.
1812 / UDP - IAS Internet Authentication Service
This service is used to process the RADIUS authentication message.
1813 / UDP - IAS Internet Authentication Service
This service is used to process the RADIUS authentication message.
3268 / TCP - Microsoft Global Catalog
Active Directory global catalog listens on this port.
3269 / TCP - Microsoft Global Catalog with LDAP / SSL
Microsoft global catalog SSL is listened on this port.
3389 / TCP - RDP
The Remote Desktop Protocol (RDP) is a protocol that makes the thin client communicates with the terminal server on the network. Based on the International Telecommunication Union (ITU) T.120 protocol, the ITU T.120 protocol is an internationally versatile standard multi-channel conference agreement, and Microsoft Netmeeting Conference Software Products is this agreement.
