Re: Firewall between DC and member servers

Tech-Archive recommends: Fix windows errors by optimizing your registry

putting a firewall between DCs and servers/clients or swiss cheese is
practically the same

I'm checking packet traces to see what goes on between a DC and a member
server since we will have a firewall in between. There are a couple things
that are not mentioned in KBs and white papers I've read. Primarily there
are
a lot of RPC calls. What are they likely to be? White papers say they are
necessary for DC replication but do not mention them for DC to member
communication. There are also pings which I believe are related to SMB on
port 445. I gleaned that nugget while playing with Windows Firewall. What
happens if there is no reponse to the pings? Will SMB fail? TIA
