I have a server for my web sites ( windows 2003 standard ). I have about 20 web sites host on this. my most important problem is DNS server , I use windows DNS Server , but some of sites and in some times , have DNS probelm , can't be found , Also my monitoring service report DNS problem and the score that set for DNS was 0 from 10.
How Can I speed up my DNS server? (any soltion or other DNS server suggestion)
Edit: Thaks for your response and suggestions. But I want to know how can I optimize my DNS server setting , in Event log I find many warning by Evend Id 7062 or 3000 , I need to know more , its low speed ralated to my setting , or Windows DNS is not a good solution. Is BIND better than windows DNS server.
