Windows 10 Win10 RDP issue - Your credentials did not work - The logon attempt failed

[Yu Fu]

I want to use one win10 laptop to connect one 2012 R2 server via RDP but always failed and get the error: Your credentials did not work - The logon attempt failed. After repeatedly trying I give it up. Hope somebody could help me with this issue, thanks!

1. Source machine: Win10 Pro, 1709, a working laptop with corporate image installed; Destination machine: Windows Server 2012 R2, client's jumping server with public access, RDP port is changed for safe purpose
2. I can see the authentication window, but failed to logon with the error "Your credentials did not work - The logon attempt failed" (sorry I'm not allowed to paste picture here...)
3. the username and password input is absolutely correct
4. both username@corporate.com and domain\username have been tried, both return the error "Your credentials did not work - The logon attempt failed"
5. all related services are started, else I won't be able to input the credentials
6. to prevent corporate firewall impact, I also tested with non-corporate network, both failed
7. the laptop was added into corporate domain before, to prevent any impact from GPO, the laptop now left the domain (checked with gpresult/r, no applied GPO), both failed
8. turn off windows firewall and tried again, failed
9. checked in gpedit.msc, no configured policy
10. uninstall anti-virus software and tried, failed
11. uninstall all Microsoft Windows update/security update and tried, failed
12. tested with my own laptop at home, I can successfully logon the destination server...

Any suggestions? Thanks in advance!
