Very strange situation, trying to access a server 2012 domain user’s win 10 pc remotely I found it would not accept his login credentials when I tried to connect from my iPad using either the MS rdp app OR TeamViewer. It is the Windows login on his pc that fails with “password is invalid” (via TeamViewer) or “the user account or password did not work” (rdp app.) I am however able to log in to this pc, through either app, using the domain admin account (as well as other users’ pc’s with their accounts.) And, I am able to log in to his account using either method from my remote PC. . . He had some issues with windows update/corrupted system store that I thought might be related, but trying a couple of other on-site pc’s that he should have access to I get the same results, so it seems to be related to his account rather than his pc. I have looked into NLA, and I remember a couple years ago the iOS rdp app had some authentication issues, but the set of circumstances seems to rule those things out. How could it just be this user, only from iOS?? Something with the iOS keyboard not correctly transmitting his password?? I have of course checked, rechecked, copied & pasted, saved, shown when entering it etc. . .
