Ensure that the DHCP Client service is started on the machines, even if their IPs are hard-set. &nbsp;Somewhat counterintuitively, this (not the DNS Client service) is used to update Dynamic DNS.<br />

Are the same DNS servers set on the problem machines as on yours?<br />

If the A record was created by a different machine or by the DHCP server and <a href="http://technet.microsoft.com/en-us/library/cc780714.aspx" rel="ugc">Allow only secure dynamic updates</a> is set on the DNS zone then the workstation may not have permissions to overwrite it. &nbsp;In this case you'll have to manually delete the record on the DNS server and let the workstation re-create it.<br />

Run <b>ipconfig /registerdns</b> on the workstation to force registration.<br />
