What to do about "Extended protection has not been enabled" messages?

Hello Everyone,

We recently upgrade our Exchange environment from SP1 Rollup 9 to SP3 Rollup 2.
I'm connected to an Server 2003 Exchange 07 SP3 RU2 MBX server and in EMC | Server Configuration -> Mailbox

When connecting to any Server 2008 Exchange 07 MBX Cluster, I receive the following popup

Get-OWAVirtualDirectory
Completed

Warning:
Extended protection has not been enabled.  Install the operating system update specified in KB968389 onto server "cluster name" and try again.

When I click on a Exchange 2007 SP3 RU2 running on Windows 2003, I don't receive this popup message for that cluster.  So do all the servers with this popup message require that KB to be installed or is it the Windows 2003 Exchange 2007 SP3 RU2 server I connecting from?

Thanks
Exchange

Thanks netcmh so this does not apply to just those 2008 servers...this is something within EMC after the upgrade.  
So I just need to follow these steps on those servers to tend use EMC to manage Exchange 07?
