NIC on domain controller

Hello,

Recently I noticed that whenever I reboot my primary DC, it will come up fine, but will not have any network connectivity.  I have to go into network and sharing, right click on the adapter, disable it, and then enable it and it will work just fine.  The server is 2008 SP2.  

Could this be a driver issue or something else?

Thanks

I would check the firmware and the driver.  Both likely need to be updated.

Def check driver and NIC firmware and BIOS firmware.  Make sure there are no other NICS or IPs configured on this domain controller.   Is it a physical or virtual? (What model physical or platform on VM?)  
Of course I would swap network cables, try a different switch port or switch (if you have multiples switches), Maybe even another NIC on the server if you have one (make sure to disable the first one you may also want to clear the IP settings out first so you don't get a duplicate IP message)
on Virtual you can try remove and adding the virtual nic or update the integration tools...
