Using the Standalone IPSec VPN client is there a way to force clients to register their VPN DHCP lease on the enterprise DNS Server?  

These are Windows 7 client PCs and we would like to be able to reach the remote PCs while they are connected via VPN to manage and update their installed applications using a package management tool.  

The VPN uses a DHCP scope managed by an ASA and properly registers the enterprise DNS host when connected, I'm just unaware of how to force the Client PC to register it's VPN pool address with DNS once it connects.
