Adding map services fails

[AhmadSALEH1]

Trying to add a map service form arcgis server to arcgis desktop, but what surprises me that I can add any layer " service " to the table of content except the Arial photos layer, see the screenshot .

What might be the issue here ?

Hi Ahmad,

Are you able to access the service through the REST directory?

Thanks Jake , Yes I can access to them.
