Ok.....You are learning a bit more about SQL Server Replication! In future you should study up on it before installing, configuring and removing SQL Server Replication as it is a huge topic!

Now......Those connections you are seeing are Replication Jobs! If you go to your Jobs Folder you will probably see 2 Jobs that were a part of Replication!

DO NOT DELETE those Jobs but Rather, I want you to tell me what the names of those Jobs are and what the Jobs are actuaslly doing before you go ahead and DELETE those Jobs.

Do that and get back to me!
