Windows NT Server PDC and BDC question

Neither *needs* to run WINS. I've lived years without it. Some other system will become a browse master.

If your network is large though, you could run it on the PDC or the BDC. It's function is more like DHCP than DNS, as the broadcast nature of WINS suggests strongly that one is the limit.

The minimum requirement for WINS in NT is one server, however it uses such a small amount of resources and gives redundancy to your WINS infrastructure so is worth installing at least one per DC and/or site.

According to this thread, you may want to keep WINS on both the PDC and BDCs.

One more article on the subject of WINS
http://articles.techrepublic.com.com/5100-10878_11-5081463.html

"Although WINS isn't necessary for newer operating systems like Windows 2000 and Windows XP, older applications and clients still use it."

So, if I am reading both articles correctly, WINS is essential to your environment and should be on your PDC and BDCs.

Great answer, thank you for your help!
