Our AD server cannot replicate with corporate AD server Window server 2012 R2

Somethings amiss, what you posted indicated FRS and DFS Replication services running when it's either one or the other and never both.   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.
