Have two older computers that we upgraded today (one actual upgrade from Win 7 Home and the other was wipe and replace - fresh Win 10 install) with Windows 10 Pro 32-bit CD from Microsoft ISO file. Computer 1 upgraded with no problem, was able to join domain, but after restart and domain user login says "the user name or password is incorrect, try again". This happens with all domain users - even administrator accounts. Have tried disjoining / rejoining.
The same users can login fine on Win 10 Pro 64-bit computers. Thought maybe it was a problem with upgrading from Win 7 home, but even does the same with the wipe and replace.
Event viewer doesn't seem to have anything specific to this problem. Any ideas?
