Introduction This post is based on a very interesting issue where an ISA Admin was publishing an internal error code 64 host not available tmg Web Server that was working internally just fine for a while. Internally the web host not available meaning server was listening on port 82 and therefore the bridging configuration on the Web Publishing rule was correctly setup to HTTP

82. However when users were trying to browse from outside they received the error below: Figure 1 – Error 64: host not available. To better address this issue we need to gather more

data. 2. Gathering Data There are three main tools that can be used to isolate this issue: · ISA Logging · ISA Diagnostic Logging · Netmon Trace By gathering this data while the user was accessing the web site and getting the error it was possible to better understand what was happening. Let’s see: 1. ISA Serve Logging shows the error 64 and more details about the connection: background: the gateway or proxy server lost connection to the web server. Figure 2- ISA Server Logging. Notice in the details pane that: · ISA is sending a GET for the FQDN of the internal web server. · Error 64 here appears with more details saying that the network name is no longer available. · Write down the Req ID because it will be used in the filter for Diagnostic Logging 2. Diagnostic Logging shows the following sequence of events: Figure 3- Diagnostic Logging details. The sequence shows: · ISA Server sending the connect request to WSRVCT.contoso.msft on the IP 10.20.20.25 – both are correct. · ISA Server is forwarding the correct path (/*) · Target host header is showing as www.contoso.com · Right after ISA Server sends this request to the target host the web server replies with a response status equals to 400. 3. Network trace shows more details about this 400 > ISA sends HTTP GET (notice the host header): 10.20.20.2 10.20.20.25 HTTP GET / HTTP/1.1, NTLMSSP_NEGOTIATE Hypertext Transfer Protocol GET / HTTP/1.1\r\n Request Method: GET Request URI: / Request Version: HTTP/1.1 Reverse-Via: ISACONTN2, ISACONTN2\r\n Host: www.contoso.com:82\r\n Referer: https://www.contoso.com/CookieAuth.dll?GetLogon?curl=Z2F&reason=0&formdir=3\r\n User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727)\r\n Authorization:NTLM TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFAs4OAAAADw==\r\n N

Posted on 2006-03-22 Software Firewalls 1 Verified Solution 30 Comments 37,050 Views Last Modified: 2013-11-16 Dear Experts!!

This happen very often. While checking in ISA logging Query we can see the Allowed user (By checking PC’s IP) as anonymous User and access was denied.
