[Issue] - Health Checker - Get-ADObject to DC that isn't able to be reached on port 9389

[dpaulson45]

Provide Version Number
24.12.05.1718

Describe the issue
The fallback option to Get-ADObject is failing because we can't connect to the DC on port 9389. Even though we are going to eventually be connecting to the GC port to do the query, we still need to connect here first. Because of this, we fail to find our groups.

Expected behavior
We should be able to handle and find our groups. Either need to switch this to a true LDAP query or handle this a little bit better and call out that we don't have all the ports likely open to the server.

Script Output

Get-ADObject : 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.

Additional context
Get-ADComputer is working because we didn't force the DC that we are connecting to.
