Re: Recommended Inter-Site Transport for AD

This is a common misnomer, AD supports only 3 replication transports -

1. encrypted RPC
2. compressed RPC (comes in 2 flavors, 3 assuming you include off)
3. SMTP

Both 1 and 2 support replication of any kind of AD partition, 3 does not
support domain partitions.

The interface represents replication-transport-option #1 as it should be
(RPC), #2 as IP (let's not bother asking why) and #3 once again as it
should be (assuming anyone has ever used SMTP :o)

Changing connection objects in the manner you reference is of no
benefit, I'm afraid either the advice you received is incorrect or your
memory is ;o)
