AD domain user not able to login when connected to internet but can with cached login

Question

I have a user who when trying to login to their account it spins on the welcome screen for hours. If I disconnect them from the network connection (unplug ethernet and turn off wifi settings) they can connect through cached credentials.

I have checked the time server settings, verified the account isnt locked, the password isnt expired. But I am kind of lost past that.

Any help would be great.

Answer 1

Please run;

Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log (run on PDC emulator)
repadmin /showrepl >C:\repl.txt (run on any domain controller)
ipconfig /all > C:\%computername%.txt (run on EVERY domain controller)
ipconfig /all > C:\problemworkstation.txt (run on problem pc)

Also check the domain controller System and Replication (DFS or FRS) event logs for errors since last boot. Post the Event Source and Event IDs of any found. (no evtx files)

then put unzipped text files up on OneDrive and share a link.
