Windows 10: We can't sign you in with this credential because your domain isn't available.

I am getting this error message while changing password of my domain account. I have alternate UPN suffixes in my AD DS, i.e. contoso.com.np as Primary domain name and contoso.com as alternate UPN suffix. Please suggest the solution for this error.

we can't sign you in with this credential because your domain isn't available.

Greetings

We are a small company with 25 Computers, which are connected to the domain server and hold Windows 7 Pro licenses. We also have a Windows 2012 DC/AD.

We are in the process of moving the Operating System on all the machines to Windows 10 pro (or enterprise - we do have licenses).

I've started testing three machines by upgrading them to Win10 Pro back in 2016 from 7 to 10, then join the windows server to which they were more than happy to accept. but shortly after, I could not log into the PCs with domain users unless the profile
was already made. so if the domain account exist in the system, I can log in, if not I get the message:

"we can't sign you in with this credential because your domain isn't available, make sure your device is connected to your organization's network and try again. If you previously signed on this device with another credential you can sign in with
that credential".

Local accounts work, the passwords are correct 110% and am not able to login, I can ping the DC, in fact I can remote into the server from the same PCs. and they all act the exact same way.

The closest answer I got was on this site:

Samba - General - We can't sign you in with this credential because your domain isn't available

to which I assigned the DNS on the PCs to the DC server. and still no luck.

also am up to date with my windows Updates.

help is appreciated not just for me but all those who need it

Thanks

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

Cortana isn´t working

When I hit enter, it did something, but there´s still no Cortana, even after restart. So I tried it again, but now it says that it failed, because it´s already installed and it´s working in PC. So it should work, but Cortana still isn´t here.
