From within our domain when we access our external website at www.abc.com it's very slow. We have a forward lookup zone on our internal DNS server for abc.com. In our forward lookup zone we have the appropriate A records that point to the externally hosted website.
If within my network I change the Primary DNS on a workstation to use an external public DNS server, then accessing our external website is nice and quick.
So, any thoughts on why it's slow and what short of deleting the lookup zone we can do to fix this?
