Hello,
I am having trouble opening the Active Directory Administrative Center due to the error message "Cannot connect to any domain. Refresh or try again when connection is available." My network has two servers and two domain controllers with DNS pointing to PDC and secondary DC pointing to PDC's IP address. DFS Replication is active, the firewall is off, and the Active Directory Web Services are running on both servers. Active Directory Users and Computers work fine, but the connection issue persists.
I have checked the Active Directory Web Service on both servers, and they are listening on port "9389." What should I do next to resolve this issue?
Server1:
DC: \DC1
Address: \192.168.100.180
Dom Guid: xx
Dom Name: test
Forest Name: test.domain
Dc Site Name: Default-First-Site-Name
Our Site Name: Default-First-Site-Name
Flags: GC DS LDAP KDC WRITABLE DNS_FOREST CLOSE_SITE FULL_SECRET WS DS_8
The command completed successfully
Server2:
DC: \DC2
Address: \192.168.100.181
Dom Guid: xx
Dom Name: test
Forest Name: test.domain
Dc Site Name: Default-First-Site-Name
Our Site Name: Default-First-Site-Name
Flags: GC DS LDAP KDC WRITABLE DNS_FOREST CLOSE_SITE FULL_SECRET WS DS_8 DS_9
The command completed successfully
I have checked the ports on both servers and ADWS are running.
I found [Microsoft.ActiveDirectory.WebServices.exe] is listening different ports.
