Is there a command within the IOS that tells DHCP clients to register with DNS & reverse DNS?
Cisco IOS Software, 2800 Software Version 12.4(25f), RELEASE SOFTWARE (fc2)
Cisco DHCP is only being utilized for the connecting VPN clients (PTPP)
Thank you for your time in advance.

No.  That is something the MS DHCP server does.

if the DHCP server service is done by MS DHCP server, just configure its DHCP options for the client side settings.

Windows clients should automatically try to register with DNS. Otherwise, use Windows DHCP instead of Cisco DHCP.

Windows clients only update their DNS records via DHCP and then that's only if the DHCP server supports the DNS update function.  If the client uses a a Cisco DHCP service on a switch or router this won't work.

That's the information I am looking for!
Is there any way to update DNS when DHCP is done on the Cisco device? Any way at all?

Do you have any documentation on this?

Thank you very much for your reply!

'Some' versions of IOS have the DHCP update dns feature, which is really only meant to be used in two scenarios...

1] Where you are wanting to update DDNS records using a DDNS provider
2] Where you're using the local IOS device as a DNS server.

Look at this guide...
http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dns/configuration/15-sy/dns-15-sy-book/dns-dyn-dns-supp-ios.html#GUID-397E7B02-B413-4BD5-AB62-96D3A808BB5B

You 'might' be able to try this by pointing the DNS config at your MS DHCP server and usually updates PTR records with no issue, but isn't successful at creating or updating A records at all.  This may be down to security permissions, and I wouldn't advise you change those on your MS DNS server unless you want to risk killing your AD!
