IP Selection - Organizational Units does not work in Auto Discovery

When you are setting up the domain groups, have you added the domain to the settings in PRTG? These settings can be found in the System and Website settings under Web server and website settings. There you will find a field that needs to be filled out for the domain. If that is filled out and still is not working, you may need to provide credentials for a domain admin to access AD. You can do that in the field directly under the field for the domain.

Yes I have added those information. Active Directory Domain: gold.local Active Directory Access: Use explicit credentials Active Directory Access User: Both are provided.

I have done that. Active Directory Domain: gold.local Active Directory Access: Use explicit credentials Active Directory Access User: Already supplied

What errors are you getting exactly? Have you tried to reset the AD domain to nothing and then save the settings and then set it back and save the settings?

When I add a Auto Discovery Group via Active Directory, this is the error that appears:

Oops...

The validation of at least one of the new objects failed because of the following:

Your IP selection must result in 1-65536 IP addresses

The object was not created.

Please let me know what seems to be the issue at hand.

From the error code, it seems like the OU that you are trying to use either doesn't have computers in it or PRTG cannot resolve the names of the computers. If you have sub-OUs, too, please consider the correct syntax in the format Y,OU=X : OUs that are part of another OU have to be listed together with their parent(s). Enter the sub-OU followed by ,OU= and the name of the parent OU. For example, assuming that the organizational unit 'Y' is part of the OU named 'X'. Then the syntax would be Y,OU=X . For three OUs 'X', 'Y' part of 'X', and 'Z' part of 'Y', the syntax would be Z,OU=Y,OU=X . Note that the order is important, sub-OUs have to be listed left of its according parents!
