The SAS Deployment Tester plugin and the Configuration Manager get installed as part of a planned deployment (using a plan file), which would be how your server was deployed. On the workstation, if you installed SMC without using a plan file (Install Additional Software) then you would not get SAS Deployment Tester plugin (client) and Configuration Manager manager unless you explicitly checked the boxes for them on the Products to Install panel of the SAS Deployment Wizard.
I'm unsure about the fonts thing. Possibly just a difference at the OS level.
