Has anyone seen an issue in 10.4 Admin Console where AD users are not displaying (only SIDS display) or when adding and AD user, once selected the user name does not return with only a "\" displaying?  I've seen this twice in the past week on two entirely separate systems.  In both cases, the resolution was to remove the workstation from the domain and the add it back again.  Wondering if this is a bug in 10.4 Admin console itself or an artifact from upgrading (in both cases they were upgrades)?

Thanks...
