Hi,

One of the apps which is misbehaving through this is actually Visual Studio 
2005, namely the TFS components :).

I haven't looked at the config, but apparently it is causing errors regarding 
not being able to connect to the proxy etc.

Also some external PHP stuff - one of them downloading stuff via Pair and Zend 
studio.

Andrew.

Don't let your users define your ISA policies.
There isn't a (current) operating system that *can't* authenticate using NTLM.
MAC, xNix; whatever.
Tell your "developers" that if they had any sk1llz, they'd already know how to 
use NTLM auth, as it's been in use for many years.
http://msdn2.microsoft.com/en-us/library/aa378749.aspx is a good starting 
point, and there are several public descriptions of NTLM free for the searching.

Basically, your need to know who is doing what through your firewall is far 
more important than their need to get through it.
Get your C-level management behind this policy or you'll soon have a Microsoft 
Pix Server operating at your edge.

Hi,

I have NTLM authentication set on the ISA firewall rules for specific IP 
ranges.  I am getting shouted at by developers and people using specific apps 
because the proxy is not allowing them to authenticate through - or more 
correctly, the application isn't allowing it through.  These are most often PHP 
developers using various PHP based applications etc.

I have created a rule which excludes specific IP addresses from authentication, 
which is working, but more and more people are now requesting this.

I wanted this initially for the Websense logging system - but is there any 
other way round this?

Thanks.
Andrew.
