Hi amakki,

I noticed in this document:

http://www.microsoft.com/technet/prodtechnol/isa/maintain/isaimsec.mspx#XSLTsection122121120120

That it requires MSN Messenger version 5.  What version are your users running?

Cheers,
IceRaven

OK, Netman thanks for help but this not my configuration I am running ISA in cache mode no firewall installed on ISA , we have other firewall machine doing NAT from inside to outside , this is not the problem in cache mode in ISA there is no protocol definitions othere than HTTP,HTTPS, FTP, Gopher and other protocol , I am using authentication to authenticate the users from the outgoing interface  all when I try to open MSN messenger it gives me message that your proxy requesting for authentication this is not exactly the message but it means that ,also I tried to use SOCK5, SOCK4 and HTTP connections with MSN messenger but nothing work with different MSN versions but also  same thing not working.
I allow everything I have two protocol rules to allow everything (Site and content rule and protocol rule)
Can you try to find with me the solution I will be thankful.

Highfive + Dolby Voice = No More Audio Complaints!

Hi amakki,

You're running in cache mode - you say "outgoing interface" so does this mean you have two NICs?  Is the ISA inline or between the LAN and the router or the other firewall?  

What are your Authentication settings in the Security tab>Intranet space?

This is for Yahoo messenger, but you could try it:

Yes Netman exactly I am using two NICs and ISA server is inline between the LAN and the firewall (Cisco Firewall)  the outgoing interface is connected to the LAN and the incoming connected to the firewall and the authentication used for outgoing is Integrated I don`t know what you are talking about Security Tab>Intranet space??
I appreciate your help and I hope this information will help me to help you find the solution together.

Ok, a little terminology differences!  The LAN-facing NIC is generally referred to as the internal NIC and the Router-facing NIC is the external interface - when speaking ISA-ease!

You can disable Authentication on the ISA if you only use it to cache.

What I was referring to was this:

In IE, select Tools>Internet Options
Select the Security tab
Select the icon representing the Local Intranet
Select the Custom Settings button.
Scroll right to the bottom - there are Authentication settings there - what are yours set to?

Try changing to the next one down - Auto logon using current username/password.

Also, in Internet Options, on the Advanced tab - there is a setting for HTTP 1.1 settings - try selecting both options.
