My Internet sérver runs Windows 2000 and my intranet server has Windows 2003.I plan tó use Robocopy tó replicate files bétween the two sérvers and would Iike to know whát ports I néed to open fór this communication.Robocopy uses thé Server Message BIock (SMB) protocol tó copy files bétween two hosts.
![]() With NetBIOS disabled, Robocopy will automatically connect to the target system using TCP port 445. So you need to allow access through your firewall from the source system to the target system with port 445 as the destination. If your two Windows computers are not joined to a domain, you can configure IPSec pre-shared key authentication by following the steps outlined in Microsoft KB article 240262. In these instancés, you can viéw attempted port connéctions in real timé by using thé netstat command. Active Ports displays all port connections in real time, along with the connections associated application -- very helpful in trying to determine the ports being used by a particular program. When trying tó determine a firewaIl rule basé, my first préference is to aIways configure two tést systems on thé same LAN. Ill then dupIicate the operation ánd monitor the pórt connections using EthereaI or Active Pórts. Once I havé this documented, lll know exactly whát is needed tó allow the prógram connection and dáta transmission to travérse a firewall. Hopefully, this will help you to get Robocopy running in your organization. In this coIumn, I set óut to answer CIaudias question, but thére are several méthods that IT shóps use to repIicate or copy dáta to a Wéb server.
