DNS Forwarders vs root hint
I have two name servers from my ISP set as forwarders on my PDC.
Is it best practices to use these NS or clear them out and just use root hints?
Would 8.8.8.8 offer any benefit?
My system event log returned ID 10009 that DCOM as unable to communicate w/ each of the ISP Name servers.
No network problems, however. (isolated I guess).

Unfortunately Senthil's answer is incorrect. DNS forwarders are not required. You can use root hints as well. The answer of which to use can really only be determined by testing the responsiveness of DNS servers to your queries. You may see some improvement from using certain DNS servers as forwarders if they respond quickly, but they are not required.

Thank you footech.
Yes footech is right provided you check mark the option under Forwarders as "Use root hints if no forwarders are available" if forwarders are used.
You can just use root hints if you like. You don't have to use forwarders at all, which means that the option "Use root hints if no forwarders are available" is not required either. That's just a backup when you do have forwarders configured.
