Forefront Endpoint Protection 2010 not updating on Server 2008 R2

We have nearly twenty servers and our file and print server suddenly stopped updating FEP 2010.
I have pasted in below all error messages I've encountered:


The error message when manually trying to update it is:
Forefront Endpoint Protection could not check for virus and spyware definition updates due to an Internet or network connectivity issue... Error code: 0x80070490"


The Event Viewer logs an error with ID 2001:
