| I was wondering if anyone can give me any helpful insights into the solution to this problem:
"You are running a small, Windows 2000, routed network. You have a single, internal router so that you can have 4 subnets. You install a DHCP server on subnet A. All the hosts on subnet A successfully receive IP addresses from the DHCP server when they boot up but the hosts on the other 4 subnets do not. They are supposed to get addresses in the 172.16.0.0/20 range but, instead, they end up with addresses in the 169.254.0.0 range. You are considering installing a DHCP server on each subnet but are hoping there's some other way."
I'm stumped | |

| Install a DHCP relay agent on each subnet | |

| That looks the same as one of the tests on the exam. Just like spud said. DHCP Relay Agent | |

| an ip in a 169.254.0.0 range is a APIPA address!!.
Windows 2000 uses Automatic Private IP Addressing (APIPA) to automate Internet Protocol (IP) configuration of network connections when your computers can`t contact the DHCP server for dinamical ip configuration.
When you have a router in your network and computers in other subnets can`t contact the DHCP server, the computers can`t receive a ip configuration from the dhcp server!!!, so windows 98 / 2000 / xp assign a automatics private ip adress from the OS in the range 169.254.x.x/16.
In this case, you must install a DHCP relay in each subnet so computers in the subnets can receive a configuration from the DHCP server.
Best regards

| Every time you see a 169.254.x.x ip adress in your computers or workstations, you must know that you have a problem: cable connection lost / problems with your nic / unable to contact DHCP server / DHCP server down / DHCP without free ips to lease, etc....
see the info below extracted from a MS site..
By default, the computer first tries to contact a DHCP server on the network and dynamically obtain configuration for each installed network connection, as follows:
If a DHCP server is reached and leased configuration is successful, TCP/IP configuration is completed.
If a DHCP server is not reached or leased configuration fails, the computer uses APIPA to automatically configure TCP/IP. When APIPA is used, Windows 2000 determines an address in the Microsoft-reserved IP addressing range from 169.254.0.1 through 169.254.255.254. This address is used until a DHCP server is located. The subnet mask is set to 255.255.0.0.
The range of IP addresses (from 169.254.0.1 through 169.254.255.254) used for APIPA is reserved by the Internet Assigned Numbers Authority (IANA). Any IP addresses within this range are not used on the Internet. | |

| How do I install the DHCP Relay Agent? | |
|
| IN THE REMOTE SUBNETS, GET A COMPUTER WITH WINDOWS 2000 SERVER /ADV SERVER, INSTALL THE RRAS SERVICE AND CONFIGURE THE DHCP RELAY OPTIONS.
YOU CAN OPEN RRAS CONSOLE AND IN THE HELP OF WINDOWS 2000 SEARCH HELP ABOUT DHCP RELAY....

| Thanks for your help. I appreciate it. | |
|
| NO PROBLEM.
FEEL FREE TO ASK ANYTHING YOU NEED. | |

| I HOPE YOU UNDERSTAND MY IDDEAS, I DON`T SPEAK ENGLISH, I ONLY KNOW A FEW WORDS... | |

| Is there any other way to accomplish this task without installing the DHCP Relay Agent?? I hear that there is, but I can't seem to find anything relating to another method. |
