Changes needed to switch to a different domain controller server (server name and IP address)

We need to switch to a new domain controller server.  The domain name stays exactly the same.  Just the name of the domain controller server (and the IP address) will change.  What are all the places where I would need to make the change on the Sharepoint side?  The only place I can think of is in all the web.config files on the line below:

<connectionStrings>
    <add name="LDAPConnection" connectionString="LDAP://<domain controller name>.<domain name>/OU=<OU Name>,DC=<domain name>,DC=com" />
  </connectionStrings>

thanks,
