| Ok here is a question from passitnow.com
70-210 test 3.
quote:
You install Windows 2000 Professional on a Pentium III computer, and setup automatically installs the PCI network adapter. You configure the adapter to obtain an IP address from your DHCP Server and successfully establish a connection to the network. During the night shift, another employee with administrative permissions changes the network adapter configuration. The next day, you are unable to connect to the network. You run the IPCONFIG utility and find that the subnet mask is 0.0.0.0. What is the most likely cause of this subnet mask reading?
A. A duplicate subnet mask exists
B. The DHCP Server is not available
C. A duplicate default gateway exists
D. A duplicate IP address exists
I know this has to be wrong. The correct answer according to the site is C. A duplicate default gateway exists.
My answer would be B. The DHCP Server is not available or D. A duplicate IP address exists
I have never heard heard of a duplicate default gateway before.
Here is another one.

You are the administrator of a LAN supporting Windows 2000 Professional computers. You want to troubleshoot a suspected problem with DNS host name resolution. Which tools should you consider using? (Choose two.)
Netstat
Nbtstat
Nslookup
Netdiag
The site says the correct answers are Nslookup which is correct and Netdiag which isn't even a valid command.
There is also a question which requires you to know the manufacturer of a network adapter. | |

| The first one I agree with B also. As for the second one, netdiag isn't on a machine by default so you will need to install the resource kit before it will work. | |

Thanks I didn't know that one
Now I know and knowing is half the battle. | |

| I thought that 0.0.0.0 for subnet mask means a duplicate IP address and this is confirmed by the MS 70-210 2nd edition. So the answer should be D.
I don't think that the DHCP server being down would make any difference because an IP address was allocated on the LAN only the day before and DHCP addresses are leased for for a length of time which would be longer than the 1 day in the question.
As to the second question - as I understand it - netstat and nbtstat are statistics tools for TCP/IP and NetBIOS over TCP - netdiag confirms your clients connectivity and then nslookup confirms that you are in contact with a DNS server by resolving a DNS name to an IP address.
Hope this helps | |

| It dawned on me that if the DHCP server is down and the clients are set up to receive IP addresses automatically then Automatic Private IP Addressing should kick in - in which case the subnet mask would be 255.255.0.0 and an IP address of 169.254.x.x
Why is it that these thoughts seem to come so long after the original question was asked?!
Anyway - just thought it may help! | |

| I take the statement "During the night shift, another employee with administrative permissions changes the network adapter configuration." To mean that this person went in for some reason and changed the IP address to a static entry, because you are now getting 0.0.0.0. This to me smells of a duplicate IP address on the network.
I'd go with "D" | |

Windows assigns 0.0.0.0 when a dup ip exists on the network.
As for this one I'm sure one answer is nslookup, however I'm unsure of the other answer.
You are the administrator of a LAN supporting Windows 2000 Professional computers. You want to troubleshoot a suspected problem with DNS host name resolution. Which tools should you consider using? (Choose two.)
Netstat - ?
Nbtstat - Defiantly not. (used for WINS)
Nslookup
Netdiag - ? | |

I installed it yesterday when I realized it didn't come with Windows. |
