Application Group for DC to DC communication

L3 Networker

I have 2 domain controllers across 2 dmz's and i need them to talk. I have a list of ports I want to open but I want to keep it neat and create a application group. I dont see an easy way to search applications by ports.

Does anyone have a list of PA applications by name that is required for dc to dc communication ? This is not client to dc communication.

Thanks,

Justin

or maybe its as easy as the active-directory application I just found ?

Hi,

The best way is to specifiy a rule for the 2 DC with any restrictions applications. After one or two days, you create a specific report for this rule and you can see the application used between the 2 DC.

What are the services between the 2 DC? (replication, dns, exchange, AD)

The following Applications are required for AD-Communication:

  • active-directory
  • kerberos
  • ldap
  • ms-ds-smb
  • ms-netlogon
  • netbios-ss
  • netbios-dg
  • netbios-ns
  • msrpc
  • ssl
  • ntp
  • dns
  • ms-kms

Regards,

Heinz
