I checked both a working and non working computer and they are both running the same exact services

Yes I am the Network Administrator. Basically if I check my working MAC running OSX and look in the Network pref. under DHCP Client ID that field is blank. Next if I look at my sharing pref. under computer name I have "shop-mac". Next when I go into my Windows 2000 server and look in the DHCP database, I see the name "shop-mac" under the computer name field and under the Unique ID field I see the Ethernet Address of the "shop-mac". Now I know that this is the Ethernet address of the shop-mac because it is displayed in the Network pref. under the TCP/IP settings. Now if I match the DHCP Client ID with the computer name that I have in the sharing preferences on my non working MAC. Then I go into my DHCP database I will get a long Hexadecimal number for the Unique ID field and then I will get a blank field for the computer name.

I too have this same problem. Has anybody fixed it?
It is not...
...length of name (15+ is OK)
...OSX version
...long MAC address (it is IPv6 that causes this, turn it off)
...putting namd in client ID (I never do this)

I get the problem _most_ (possibly exclusively) with Powerbooks.
Can anyone refute this?

I too had this issue for a macbook pro
 

It was resolved by Yellows suggestion of: changing the computer name under System Prefs>Sharing to a shortname i.e. "TimOSX", adding "TimOSX" in System Prefs>Network>TCP/IP>DHCP Client ID field and then renewing the DHCP Lease.

Thank you Yellow for the help!! :)
