Hi, This may be what you're after. http://technet.microsoft.com/en-gb/library/cc750612.aspx Here's an section of it that may be of use to you, that it if you're clients are web proxy clients. If not read the rest of the document as it covers the SecureNAT and Firewall client configs. Configure Text Messaging Through Web Proxy To use instant text messaging (chat) through the Web Proxy service, you need to set up a default protocol rule to allow the HTTP protocol, and then add the content group to your HTTP available content types. -
In the console tree of ISA Manager, click to expand Access Policy, right-click Protocol Rules, and then click New, Rule. -
In Name, give the protocol rule a name, and then click Next. -
Click Allow, and then click Next. -
In Apply this rule to, click to select Selected Protocols, and then in Protocols, select HTTP. Then click Next. -
In Schedule, click Next to accept the default, or set up a schedule for applying the rule. -
In Apply the rule to requests from, select Any request, and then click Next. -
Click Finish to finish creating the new protocol rule. Once you have created a protocol rule, add the content group: -
In the console tree of ISA Manager, click to expand Access Policy, and then click Site and Content Rules. -
In the details pane, right-click the ISA Server default Site and Content rule, and then click Properties. -
On the HTTP Content tab, select Specified content groups, and then click New. -
In Name, type a name for the new content group. -
In Available Types, type application/x-msn-messenger, and then click Add. Hope this helps.
