I deploy computers to remote sites to support our products. These computers
are all Windows XP SP2 (+ patches). They are NOT members of our Security
domain, but are part of a workgroup. They connect to my monitoring network
using OpenVPN. (Various reasons for using OpenVPN and that may change but
it's what's in place today.)

Currently, I specify a virtual IP under OpenVPN for each unit. Then
manually register that unit on our DNS server. Is there a way to have the XP
system dynamically register it's IP address with our DNS server? Ie, a
command like Net Use RegDNS or something? I need it to register the virtual
IP assigned by OpenVPN rather than the "physical" IP assigned to the ethernet
port.

Thank you.
