Helle,
I have one quesiton about DHCP sever assign IP DNS.
There are 5 DNS servers ((ABCDE)) in our network. Three(ABC) are old and two new joiner (DE).
AB removed DNS role in Domain and offline from network. Remaing CDE DNS server, and E also as DHCP server.
But the client PCs are still remaining record the OLD DNS.
Only new Client PCs which joining later than those DNS servers are assigned New DNS.
I try flushdns, release and renew. can not fix this problem.
Can give advice how clean the old client DNS?
Brgds
