This is a new Windows Server 2012 R2 Essentials setup, This server is basically running everything on the network as you would probably expect with an essentials setup, all the client PC’s are running Windows 8.1 Pro with Update 1 and are fully patched.
It is a pretty much out the box essentials setup integrated with Office 365 and Windows Azure (For an additional offsite backup) I have added a few additional group policy settings for mapping Network Printers, the Desktop Configuration (e.g. to disable the tablet lock screen) along with opening up open some ports on the client PC’s firewall as required for Sophos Endpoint Security to be deployed.
This has been running for around a month now with only one re occurring issue, randomly when users log on to their PC Windows asks the user to enter their Domain Credentials:
“The system cannot contact a domain controller to service the authentication request, please try again later.”
This happened randomly to one user on the Monday after I had set the new network up, however this week its happened to that user again, along with three other users now. It appears once the user has logged on Windows is forgetting the users Domain Credentials:
This basically means folder redirection does not work, no files can be accessed on the server, no printers, about all the user can do is access the internet.
When this has happened adding the user’s Domain Credentials in the Credentials manager appears to have fixed the problem, however im concerned about it happening again, and to other users.
Basically I’m wondering if anyone has any idea what might randomly cause this, or how I could go about troubleshooting the issue? it really does appear to be very random when this happens.

Domain controller should not be dhcp, I think you will find issues in the log regarding this.
When doing a dc promo, or running the wizard, I am positive it throws up a big warning about dhcp and forces you to manually set the address of the nic before continuing.
I don't think the dns service likes this either and you may see log entries the dns event viewer. Go to the full post
