DNS server loadbalancing
Have a query I am loadbalacing 3 DNS Servers on LTM behind a VIP. The issue is when my windows server queries a public domain it appends my local domain suffixes to it which my public DNS Server does not understand and provides NXdomain and wasting time for those DNS resolutions finally resolving to correct domain name. Is there a way possible I can restrict this behavior on LTM so that it stops adding local suffixes so that it immidiately responds to correct yahoo.com DNS query than going around trying to look for local suffixes added domain.
