Problem
When starting univention-check-join-status it takes a noticeable amount of time (up ti 5 minutes). This happens randomly on different servers in the domain
When restarting nscd the issues usually goes away and time for this command is as expected.
Envrionment
In DNS there was an old reference to a decomissioned UCS domaincontroller so the command tried to reach a non existing server.
Solution
Remove the additional entry.
