New Domain Provider Now Web  Trickles Slow Past Firewall with no Graphics

Medium Priority
Last Modified: 2012-05-06
We recently had a company take charge of our web page for management. Our Home page is hosted outside our org by this new company. After they became the new owner of our domain, our web page comes in slowly internally and does not show any graphics.  It resolves fine to the new IP. DNS Caches and Web History were flushed on tested machines.  It also does it on a Mac (non-IE computer). Clicking on any links gives errors. We have connected in our public switch and can see the page fine.  Users outside of our org don't have any probems. Internally we have a Cymphonix filter box but that was taken off line and it didn't make a difference. We can't understand what could cause this.  I am thinking something suttle in the Cisco Pix.  Anyone have any ideas?

First thing comes to mind, is whether your internal domain and external domain are one and the same? i.e. your AD domain uses domainexample.com and your website is at www.domainexample.com.

You need to check your internal DNS to make sure you are not pointing to an invalid record.
run from a workstation:
nslookup www.domainexample.com and then do the same thing with a workstation connected to your public switch.  Do you get the same results?
