I have a website that is running on IIS 6. The site is built in Visual Studio 2008 using the Crystal Reports plug-in.
When I access it via the DNS A-record, it runs at least 10 time slower than when I access it via the IP address.
When I resolve the A-record with nslookup or something, it resolves quickly, so it is not actually a DNS resolution problem.
I am completely stumped as to what could be causing this. Any ideas?
