One of my students was getting a strange error when he was creating an ordinary Replication Agent.
He copied the default agent, and updated the transport URI. He was getting a strange error to do with "Timewarp.
I have tried again on his server, but it worked fine for me. The error was in the log. I did notice he had Activated the default Replication agent .
I'm attaching the error here - If someone can tell me what it means, that would be great
