Hi All,
Been trying to add new DC at remote site which is connected through vpn to no success, there was a dc previously and was demoted ( by a previous admin), now i want to add new DC for faster logon, when try to add the new DC, i got this error message : The number of DNS servers registered as authoritative name servers for this domain could not be determined. Error: This operation returned because the timeout period expired, when i checked dcpromo logs,
