Các giao thức lớp mạng, IP (Internet Protocol), cung cấp địa chỉ cho các nút mạng và các phân đoạn. Lớp vận chuyển giao thức, TCP | 274 Chapter 7 Sizing the Infrastructure for Windows 2000 Figure Performance monitor for replication traffic. Figure Replication monitor. Sizing the Infrastructure for Windows 2000 Chapter 7 275 Figure Network monitor. The problem with using the Network monitor lies in the fact that it captures every packet and does not filter at the capture level according to the packet type. What you can do however is to set a port for RPC traffic by configuring the registry key at HKLM System CurrentControlSet Services NTDS Parameters TCP IP Port. Once the port for this is set you can start the Network monitor. Next you will need to force replication by opening the Active Directory Sites and Services console then right-clicking on the NTDS Settings objects below each domain controller object and selecting Replicate Now. Once replication has completed you can review the captured packets for those with the port number you configured. Those will represent the RPC traffic. If you have configured a site link to use SMTP traffic you should also look for packets using port 25. Server Placement Which servers do you place into which sites Do they have to be domain controllers Do they have to be Global Catalog servers Which sites need DNS servers or DHCP servers Where do you put a RAS server for dial up Where do you put a RAS server for VPN What about a branch office with 276 Chapter 7 Sizing the Infrastructure for Windows 2000 30 users do they need a domain controller or just a file and print server Now server placement seems to be a dilemma but it is one that is easily solved. First there definitely will be an impact on your network traffic when you place servers in various sites. The availability of the Active Directory is directly affected by the placement of various types of servers as well. Domain Controllers When you start this exercise you should already have a site topology plan for your network. This will be your starting point for
