those features are greyed out why is that?
also on 2.4 it was possible to reverse dns lookup how can i do that with this version?
If the Reverse DNS Lookup option is enabled, then the tools will attempt to perform a reverse lookup against your DNS servers to determine if the computer name returned matches the computer name that the tool was run against. If this name doesn’t match, it will give an appropriate message. By default the Reverse DNS Lookup option is disabled as not all environments will have reverse lookups enabled on their DNS servers.
thanks in advance =)
