SBS 2008 DHCP server not registering DNS from workgroup XP

Made sure I was set for
- secure and unsecure registrations
- separate username in DHCP
- member of DNSProxyUpdate group
- deleted reverse records
- restarted services repeatedly

and kept getting DNS registration failed in DHCP audit log

but this KB saved the day
A Windows Server 2008-based DHCP server does not register DNS records for earlier version DHCP clients that do not send option 81 to the DHCP server

the hotfix dowload didn't actually work for me - was a Vista x64 version that reported incompatbile with SBS 2008.

However going back to the problem PC and adding the local domain suffix (xxx.local) into the TCP/IP settings did the trick
