JCS Tech Services recently removed everyone's access to the ADUC (the Active Directory User and Computers) tool due to the upcoming move to the auto-provisioning of all JCS accounts. The ability to assign computer printers was lost as well. We are working on a process to allow that access.
For now, if you need to assign a printer, place an IT Ticket so we can assist you remotely. We should be able to address it fairly quickly if you can't wait until your scheduled tech visit.
