secure website and active directory integrated dns

[Guest]

I am having an issue where users from some sites on our vpn wan cannot access
a secure website, getting simply: cannot find server or dns error. The odd
thing is this isn't happening to all sites. https://ww2.site-secure.com is
the site. I have tried adjusting very loose security on internet explorer, I
even added the site to trusted sites. We are using server 2003 and win 2000
server domain controllers with active directory integrated dns running on all
domain controllers.

I am having an issue where users from some sites on our vpn wan

https://ww2.site-secure.com is the site. I have tried adjusting very

Did you start by checking your MTU accross the WAN link?

Try ping -f ww2.site-secure.com -l 1472 (1500 - 28 bytes overhead)

IF it times out you have an MTU problem, reduce the 1472 incrementally until
the ping returns, set that as the NIC's MTU.
