博客围绕Coho Vineyard管理员使用RIS在网络上部署Windows 2000展开，因部分客户端计算机找不到GUID影响部署，介绍可使用Network Monitor捕获客户端计算机的DHCPDiscover帧，在数据字段中搜索十六进制格式的GUID来完成部署。

QUESTION NO: 32
You are the administrator for Coho Vineyard. You are using RIS to deploy Windows 2000 on your
network. You want to direct your client computers to specific RIS servers for deployment. You cannot
find the GUIDs on several of the client computers. You need the GUIDs to finish your deployment
process.
What should you do?
A. Use Network Monitor to capture the DHCPDiscover frames from the client computers. Search the data
fields for the GUIDs in hexadecimal format.
B. Use Network Monitor to capture the DNS frames from the client computers. Search the data fields from
the GUIDs in hexadecimal format.
C. Use Network Monitor to capture the DHCPRequest frames from the client computers. Search the data
fields for the GUIDs in hexadecimal format.
D. Use Network Monitor to capture the DHCPOffer frames from the client computers. Search the data
fields for the GUIDs in hexadecimal format.
Answer: A
Explanation: When a client requires an IP address, it broadcasts a DHCPDISCOVER packet, which includes
the Globally Unique Identifier (GUID), to find a DHCP server. The DHCP server then responds by sending a
DHCPOFFER packet to which the client answers: with a DHCPREQUEST packet. Finally the DHCP server
acknowledges the lease with DHCPACK packet.
Incorrect Answers:
A: The Globally Unique Identifier (GUID) is included in the DHCPDISCOVER packet and not in the DNS
frames.
B: The Globally Unique Identifier (GUID) is included in the DHCPDISCOVER packet and not in the
DHCPRequest frames.
C: The Globally Unique Identifier (GUID) is included in the DHCPDISCOVER packet and not in the
DHCPOffer frames.
