Hi,

i have a setup with ISA 2004 EE with 2 Servers and GFI Webmonitor and Websense installed.

If a user open his IE5 for the first time and enters a URL it takes 7-8 seconds for the error message

"Error: Server or DNS not found.."

After a manual refresh (F5) everything is amazing fast. Every URL is resolved, there seems to be problem with authentication.

I use Integrated Authentication and every user need to authenticate.

The Clients are NT4 with IE6 in a Windows 2003 Domain (Interim Mode).

The ISA Servers are configured with two NICs. One for the internal communication. the second for the perimeter.

The internal has the dns and gateway IPs.
The internal DNS servers are only forwarders to the internal DNS servers and the external dns server.

Any idea why the authentication process is so slow?

The chances are the problem lies with Websense authorising the user against the domain. How are you configuring Websense (NTLM mixed mode or AD Native) ?
