No longer able to RDP into Azure MS 2012 server after changing VM size

After I upgraded the size configuration of my 2012 VM Server, a mandatory reboot took place. Upon attempting to login, this error occurs both from the my network and directly from the Azure Portal:

An authentication error has occured. The local security authority cannot be contacted. Remote computer: 'servername'. This could be due to an expired password. Please update your password if it has expired.

I can ping the the server and see it on the network. Because it is in Azure, I cannot login locally. From the Azure portal toolset, I am unable to reset the RDP configuration, nor can I change the Admin password. When attempting to use the Azure tools to do this, it simply states it failed with no other details. I even changed the configuration size back to what it was, but issue persists.

Any help or insight to this issue would be greatly appreciated.

Usually when you revert back to the original size the situation can/will be resolved, this has to do with the fact by changing the VM size you change hosts (normally), this causes the adding of a new virtual nic which doesn't copy the previous TCP/IP settings ... By reverting back settings normally change back to the original... Hope it makes sense.

Now, since you already tried that, that doesn't seem to work ...

Did you try with recreating the endpoint of this VM? Maybe thought about recreating the VM?
There's an extensive troubleshooting list you could run over, if you haven't already.
