Guest Dave Posted January 3, 2008 Posted January 3, 2008 I am studying for my MCSE and I came across a practice question that is coming up with mixed results. Q: You set up a reservation for a file server of 192.168.1.105 You setup a DHCP scope for all servers of 192.168.1.100-192.168.1.120 You also configure an exclusion range of 192.168.1.103-192.168.1.106 The file server is not recieving its IP address. Is the problem the exclusion range which includes the 105 IP in the reservation? One source says yes, but another source says no, and something from Microsoft seems to indicate no (http://technet2.microsoft.com/windowsserver/en/library/ab8ae112-34c5-49b5-9795-155d89035f0d1033.mspx?mfr=true 3rd bullet point at bottom)......However that does seem to be the problem.... Can anyone elaborate?
Guest - Michel Posted January 3, 2008 Posted January 3, 2008 RE: question about DHCP and exclusion range and reservations Hi, Your practise should work: the reservation overrules the exception. If your server does not receive an address, you might want to check the MAC address (typo?) or the cabling. I assume other machines are receiving IP's (ie: you tested the functionality of the DHCP server)?

Guest Dave Posted January 3, 2008 Posted January 3, 2008 RE: question about DHCP and exclusion range and reservations so basically reservations OVERRIDE exclusions?

Guest Newell White Posted January 4, 2008 Posted January 4, 2008 RE: question about DHCP and exclusion range and reservations There is a corollary: "Reservations in a scope must be defined on all the scope's DHCP servers to be 100% effective" This is not made clear by existing literature. -- Regards, Newell White "- Michel" wrote: > That is correct. > > "Dave" wrote: > > > so basically reservations OVERRIDE exclusions? > > > > "- Michel" wrote: > > > > > Hi, > > > > > > Your practise should work: the reservation overrules the exception. > > > If your server does not receive an address, you might want to check the MAC > > > address (typo?) or the cabling.
