I am trying to connect to a remote server via Active Directory Cmdlets like
"Get-ADGroup -Server xx.xx.xx.xx" (Microsoft.ActiveDirectory.Management.dll).
The connection can't be established although the ports 9389 (ADWS) and 636 (LDAP) are open. Message is:
Get-ADGroup: Unable to contact the server.
This may be because this server does not exist, it is currently down,
or it does not have the Active Directory Web Services running.
Are there any other ports necessary to create a connection?
