Running ZCM 11.1 employing a DLU policy. Have an issue authenticating especially on one workstation with error:

"Unable to log into the ZENworks realm because the system has disconnected from the network and the specified credentials did not match with credentials cached on the system"

Some research points to removing User Source Connection and re-establishing. When attempting, Remove option is inactive with following bubble:

"This menu is enabled only when a single item is selected"

Only one connection exists, but its coupled with the generic "Connection" check box. What gives? Or, is there a better approach to resolving?

Thanks for any help.
