You may refer to the following thread link and check:
1. What is the complete message you are getting?
2. Do you receive this message when you use any Office application or while using Office Web Applications?
3. Have you made any recent changes on the system?
Run the Network troubleshooter first to see if it can help diagnose and solve your problem.
