DFSR with Static port

Hello All,

I read an article http://blogs.technet.com/b/askds/archive/2009/07/16/configuring-dfsr-to-a-static-port-the-rest-of-the-story.aspx to configure DFSR with static EPM port.

I read about command dfsrdiag /staticrpc /port:55555 /mem:fileserver1

I have two questions regarding this.

1) If we have three servers (1 in each of 3 sites). Server A replicates to both B and C. If we run the command mentioned in article on both Servers A and C. How will Server A and B replicate with reference to higher ports.

2) Is there a way to undo the command?

Appreciate any help!!
