Problem with the internet browsing, even with only one PC behind the server, I can surf the internet but much slow if I'm not behind the ISA server. However I can download with normal speed (using IDM) and the ping is normal.

I have very simple network:
ISA server 2006 SP1 installed on Windows server 2003
2 Network cards ( 1st Wan, 2nd LAN)
DHCP service enabled with router and DNS option

in ISA server I add this access roles
Allow all outbound traffic from Internal & local host to External
Allow DHCP Request
Allow DHCP Replay
Allow DNS for all network

I don't have internal DNS, nor Web publishing server. Just the server and 1 pc at the internet (for testing)


I know this maybe discuss a lot but I search & tried almost everything, no luck

Please advise...

I don't think it's isa problem, save some internet page on your pc and browse them. if the problem continues then its your browser or os problem

So far nothing wrong with PC when I tested the browsing on it with no ISA in network.
The problem in browsing appear when I put the PC behind the ISA server.
I can download with normal speed, and Pages loaded, but much slower than if the pc is connected directly to the internet. Specially for some sites like Facebook.

Any suggestion would be appreciated....

And is the browser confugured to use it?
What is the response time for DNS querys? (from ISA server or client, depending on the Proxy configuration)

the internal web proxy is enable but the auto proxy discover is not configured. Thus in session logs u can c SecureNAT clients, and web proxy Client with anonymous.

NO the client use no proxy setting in their browsers.
