ISA 2004 (Error Code 64: Host not available) gives intermittent and random error.
Posted on 2006-03-22
Before I start, I would like to mention that I tried the solution from an expert article "Q_21483635.html", but no luck. We have even opened a case with Microsoft PSS, and its been 10days now without any breakthrough. We have an ISA 2004 Server with Service Pack 2 running on Windows Server 2003.
The problem is explained below..........
When user browse the Web Page. It will open for two or three pages. Intermittently, it will not open, and we need to click refresh for browsing. 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. If the same User when refreshes the browser they can able to browse and in ISA logging Monitor we are able to see the particular user's login name.
Technical Information (for support personnel)
· Error Code 64: Host not available
· Background: The gateway or proxy server lost connection to the Web server.
· Date: 3/11/2006 8:12:21 AM
· Server: prxycity1.internal.com
· Source: Remote server
Just to eliminate doubts on network side, we tried accessing the internet directly without the Proxy server, and things work normal, but with ISA the error keeps coming randomly.
