It is a test server and we are trying to hide it from the network while keeping it available to users who need to access it. Just changing the listening port is not enough to hide it, the other ports need to be changed also.

Is the goal to make the server not show up on the repository list on the Client's start screen or when users try to attach a repository?

Yes exactly but without disabling the automatic search on the client machines. We just want the server to hide and not broadcast itself.

Changing the ports will not prevent the server from broadcasting itself. Setting up the registry key described in this KB article will stop it from publishing its connection point on the domain.

I am unable to get that to work. I removed the prefix so it looks like this and restarted the service but a remote sever is still showing the repository when I run a repository search.

Right, you already have a connection point published for the server. That needs to be deleted first. The lfscpcnfg utility is located in the server install directory.

Please confirm by performing the following steps:

1. Use the lfscpcfg delete command to delete the registered SCP
2. Use the lfscpcfg list and/or query command to confirm that the SCP is no longer present
3. With the registry change in place, restart the Laserfiche Server service
4. Use the lfscpcfg list and/or query command to confirm that the SCP is not registered back

On the machine you're running the Client on, you'll want to confirm that the repository was not already attached (and hence, saved in the registry).
