Replication--Too Many Questions---Too Little Solutions

1) Do I have to install publishing on both servers (A and B) even
though one will be publisher and the other will be subscriber.


2)a. Can named pipes be used for communication between these two servers
which are on the same domain but not on the same network. Why or why
not, whatever the answer may be?
b. If I use TCP/IP, it the connection set up using the client
configuration utility? How is the connection string set up in this
case?
c. Suppose the publishing server was not using Net-Beui. Could this pose
any problems for communication. (is using lmhosts sufficient in this
scenario)


3) I have set up a (remote) SQL Server to be a Publisher/ Distributor.
Both SQL servers have been configured to be remote servers relative to
each other. Following are the steps I have carried out to set up
replication:

______On the Publication Server (a remote server)
I went to Server --> Replication Configuration ---> Install Publishing

Next, I chose a local distribution server. I think that the
instdis.sql script ran fine because the distribution database was
installed successfully.

___Next, I went into Manage Publications from Server menu to set up
the publications.


_____________When I went the subscription server to subscribe to the
published articles, I got the following error message:


Error 14093: [SQL Server] You must be System Administrator (SA)
or Database Owner (dbo) or Replication Subscriber (repl_subscriber)
to execute the stored procedure.
