   The ISA Server logs will indicate a denied connection with status that the specified URL was denied. On ISA Server 2006 SP1 in the rule properties window, you can click Test Rule, and the error An unexpected response was received from the server. HTTP response: 404 not found. is displayed.
   
   Resolution: Use the ISA Server manager to select the rule that you created in step 4, “Create a new Web publishing rule on the ISA Server.” Right-click the rule, click Properties, and then verify the following settings:
   
   
   • Listener on the Gateway publishing rule: Verify that there is no warning on this page The selected web listener is not configured with certificates matching one or more of the public names defined in this rule, and that the public name of the TS Gateway server matches the certificate name.
     
     
   • Authentication delegation on the Gateway publishing rule: No delegation, but client may authenticate directly
     
     
   • Paths on the Gateway publishing rule: /*
     
     
2. Client symptoms: Clients receive an error that the TS Gateway server is unreachable. The ISA Server logs indicate failed connection attempt with error code 0x80090332. On ISA Server 2006 SP1, in the rule properties window, you can click Test Rule, and the error Name resolution error is displayed.
   
   Resolution: Use the ISA Server manager to select the rule that you created in step 4, “Create a new Web publishing rule on the ISA Server.” Right-click the rule, and then click Properties.
