When looking at the UI on an agent machine most tasks are listed as "Queued task cannot start"
You will see one of the following errors in the client logs.

Description: Select: Unable to select a server. This may be because all servers are excluded, have reported more than 20 errors recently, or are not responding to speed tests.
Date: Sep 22 11:21:39:015
Description: Unable to start SWD task 'Software Update Agent Install': No server is available
Date: Sep 22 11:21:38:000
Description: Failed to resolve host name: 'svr.domain.com' or 'svr': The requested name is valid, but no data of the requested type was found (-2147013892)
Naming resolution is not happening correctly.
Correct the naming resolution, in one case they just added a line for the server to the Host file.
You could also change and use the IP Address for communication instead of the machine name.
