Cannot delete remote server

Trying to delete remote server 'DVA'

- When I go to delete the 'DVA' from the list of remote servers I get
- Error 15190: There are still remote logins for the server 'DVA'

I execute the following statement to list remote logins

- execute sp_helpRemoteLogin

the output returns

SERVER | LOCAL | REMOTE | OPTIONS
T1 | Distributor_admin | distributor_admin | trusted
T1 | Distributor_admin | sa | trusted

Fair enough I go to delete those remote logins using

- execute sp_dropremotelogin 'DVA' ,'distributor_admin', 'distributor_admin'
- execute sp_dropremotelogin 'DVA' ,'distributor_admin', 'sa'

but.. get the following error messages

There is no remote user 'Distributor_admin' and 'sa' mapped to the local user 'distributor_admin' from the remote server 'DVA'

Don't understand why it is not finding those logins and how to resolve?It almost sounds like a publication is still active on the server. Is that true.

Can you drop the publication(s) and then check to sede if the remote server is still listed?
