I am trying to move(basically I am trying to copy) the data in edirectory from one windows server to other. I am trying to use the Import Convert Export Wizard in iManager to create a LDIF file of the data.
But while entering the server information from which I have to export the data, I am getting this error:

Error: ICE Wizard Error
Unable to connect to the requested server. Verify the name/address and port.

Here are my questions:

1. What could be the possible cause of this error?
2. In case if telnet is disable or not present in any of the server, can cause this error ?
3. Is there any other way/method by which I can replicate/copy data in edirectory between 2 different windows servers ?
