Build the link:

1.) after you created the eclipse update site open the application/database properties and switch to the information section.

2.) copy the replica ID to a text editor (without the ":" character)

3.) now build a link similar like the following:

NRPC://domino01/__C125742500705A55/site.xml

Note the use of the double underscore and replica ID in the NRPC protocol.

Note:

You need to change the replica AND the sername name so that it match to your environment.
