IPSEC

-

i have a customer wants enable encrypted communicatons around 20 servers , 1000 desktops.  subset of around 8000 workstations , 200 servers.  in single ou specific operations.  healthcare requirments need encrypt lan traffic.   thinking using kerberos ipesec policy using "secure server" way initiate encrypting said servers , still able communicate servers not participating in policy. 

 

the question have can create policy ou? reading state enable in default domain policy. cant other reasons.  want servers/clients in ou.

 

i figure kerberos easier implement , dont require internal pki or have deal ssl.

is there anyting might on looking or need condsider? 

i believe can accomplished single gpo linked @ ou correct?

its mix of xp/2003/windows 7/2008.  know need use 3des.

thanks, grady vogt

yes, can configure required ipsec , connection security policies via group policies in 1 or multiple gpos linked ou have workstations , servers requiring lan encryption using ipsec. recommended filter gpos using security groups , or wmi filters limit scope of clients , servers affected policy.

you need configure 2 different sets of policies, first policy applies servers , configure server require ipsec protection inbound connections , request ipsec protection outbound connections. second policy applies clients , configure client request ipsec protection for incoming and outgoing connections.

having mixed environment of os versions requires configuring a mix of "legacy" ipsec policies , "new" connection security policies.
