This forum is for standard Creative Cloud users and we cannot troubleshoot enterprise issues here. I suggest you get ahold of your company's IT representative. You should also have access to enterprise support, who can help you with this issue.
In the few cases from enterprise that I have seen relates to "blocked ports" not allowing the interchange of data that is crucial to this service functioning correctly.
If you still need help troubleshooting after you've tried some of these things, kindly return here to the post for a follow up. We hope to hear good news coming back that the issue is fixed. Hope your IT admin onsite can help you check those ports to make sure they are working right. Enterprise support can work with him or her on this task, for sure.
