Hi guys! I have a little bit knowledge on MCSE platform.I have a question regarding DNS Server.My friend asked me a question. DNS server failed what type error u are getting? i)when local DNS server failed ii)if connected one on the Internet dns server? Till now i didn't work on dns server. Can any one tell me. Thanks in advanced

Sounds like a test question to me but... If you DNS server fails, Active Directory stops working. You can't resolve host names (except perhaps local names depending on how things are set up). You can't find services, like a domain controller for example. DNS is sort of like the phone book that helps computers and services be located.

while we are login time.what error will show.If active directory stops working. Second thing eg:-In the local they have a IBM server eg:-techgfx.com.They connected to 30 clients on that server. Thanks for replay.

i) you can't logon with message can't authenicate ii) page not found Imagine the power if you knew how to internet search
