When I try to attach to the repository, I get an error: The user account name of password is incorrect. [9010].  It does not allow me to try to login.

I do not have the checkbox for windows authentication checked.  I get the error through the 'attach repository' dialog box.  It does not allow me to attempt to login through the start page. 

This repository has defined users and groups.  Would attempting to do this with a new repository with no defined users have different results?

On the LF server side, are you able to use the client on that machine normally or do you get the same message?

How many repositories do you have?

If more than one, do you get the same behavior on all of them?

If it only happens on one, is the problem repository a copy of the other?

The client on the workstation with the server responds normally. 

There are two repositories, an old version of demorepository, with multiple users/groups, and a newly created one, with no users/groups defined (other than admin).

This happens when trying to attach to either repository.

Thanks,

It does not look like anyone has had you check the firewall on the PC hosting the LF Service.  You need to make sure that the correct ports are opened to allow communication between the external clients and the server.
