Hello,
we have forwarders and root hints configured. when we nslookup abc.com, it is not resolving, but when we change the server to the root hint server name, and then do a query, it resolves.
basically its not resolving automatically when we query external domain name. resolves only when we change the server context in nslookup to root hint server name.
verified all below settings and all are good.
Check if you have the option "Use root hints if no forwarders are available" enabled under DNS properties in the forwarders tab.- Check if you have the option "Disable recursion" NOT enabled under DNS properties in the advanced tab.
- Check if you have root hints listed under DNS properties in the root hints tab.
- Check the interfaces tab under DNS properties, how many address listen for that DNS server? Are the clients using any of these address under their preferred DNS settings
and from below link, IsSlave reg entry is 0x0 [followed below article.
