Hi Tom I am trying to authenticate the incoming user to ISA server to be able to use https://owa... I already have published OWA which is working, see below, the 1st one authenticates at the ISA server, where as the 2nd one gives me the error.

Works fine. If I enable authentication on the Web Publishing Rule to use a local group so I can control who can access OWA then I get a 'page cannot be displayed' error - '500 Internal Server Error - The network logon failed. (1790). Internet Security and Acceleration Server. This local group is made of users from a another forest/domain that is trusted by this organisation. If I allow any requests it works fine. Help!!
