What steps are involved in changing the IP address of a Microsoft Live Communications Server?

Our implementation consists of an LCS Proxy and an LCS Server. I want to change the public IP address of the LCS Proxy, from let's say 172.1.2.3 to 10.1.2.3.  We're using LCS as a SIP server (TLS) supporting a private, Internet facing, Windows Messenger network.

Thanks,

Shouldn't be a problem.
Change the IP on your AP external/public NIC properties.
Then change it in your Access Proxy console properties.
Restart the AP services.
Update external DNS (A) records for the Access Proxy with the new IP.
Update any firewall rules and routing in your DMS as appropriate.

Thanks qaanthony, I appreciate your quick response.

Updating the AP console properties and restarting are done where? MMC?

(sorry for such a basic question; I'm on unfamiliar ground.)

On the AP go to Adminstrative Tools and Open Computer Management.
Expand Services and Applications
Right-Click Microsoft Live Communications Server 2005 and select Properties.
