I formatted yesterday an older machine with Windows XP for running some old software. I was planning to keep this machine like this permanently as a legacy computer but I am facing a bug: it will not map a drive to a Windows 2012 R2 server which is a domain controller. It will connect to a non-DC Windows 2012 R2 server however. It will also connect to a Windows Server 2012 DC and non-DC.
The issue seems to be only between this Windows XP machine and Windows 2012 R2 DC (of course, all my other Vista, Win7 and Win8 machines can connect to this DC without issues).
Anyone has a clue what is wrong? Some backward compatibility setting in Windows 2012 R2? Is there anything I can do? This Windows 2012 R2 DC server is critical in my company.
