Hi,
Before going further, please confirm the following information to make the issue more clearly.
1, Which user do you used to do this?
2, What' the result if you log on to other DCs?
3, How many DCs do you have, everything works well?
Dcdiag /v >c:\dcdiag1.log
Repadmin /showrepl >C:\repl.txt
Repadmin /showreps *
Best Regard,
