MS IIS Setting: HTTP Failed To Connect if Using Machine NamePreviously I'm working on Microsoft IIS 6 on Win XP Pro SP2 to host my web application and its for development and testing purpose. Normally I use the machine name instead of localhost. So, I always use something like, http://mymachine/MYAPP/application.dll. But a few weeks ago, I had manually updated the Windows Update, guessing that it might help me on resolving security vulnerabilities in Windows, (which I'm not sure what). So after the update, I can no longer use my machine name and I have to use the localhost instead. Of course this is OK if I'm working on this machine alone, but I also need to do testing from other PC directing to this machine as well. I tried to telnet to port 80, and it failed to establish connection if I'm not using the name 'localhost'. Looks like it block the usage of port 80 if I'm using the machine name. Seems to me that this only require a little twist somewhere,... but I really have no clue where. I tried to uninstall the whole Windows Update. Tried to stopped windows firewall, stopped anti-virus, tweak system setting. But all to no avail. Can anybody here be kind enough to help me? Thank you. No need to cross post to many groups. just IIS will do.
Now - can remote machine ping the servername? telnet the server port 80 remotely? If you able to do so, what do you see when test browse a hello.html remotely? -- Show quoteHide quoteRegards, Bernard Cheah http://www.iis.net/ http://www.iis-resources.com/ http://msmvps.com/blogs/bernard/ "Ahmad A.

Windows Update ? Was SP 2 part of the new service applied? When you say "all to no avail" what do you mean ? that you could not shut off the firewall or that it made no difference? That you pull up content with localhost shows that IIS is working. Use of localhost does not go out the network interface, so either tcp 80 is not being allowed in or the website is configured with hostheaders to only allow response when hit upon with certain host names (like localhost) in use.

its working well (I can go to port 80 using machine name). Yes. It's like tcp 80 not being allowed to accept connection if using the the machine name. I had actually experienced this twice in different machine. It all happened after I applied Windows Update. I do not sure which Windows Update package because I normally download and install a whole bunch of them. After I installed them and reboot, then it happened. I'm sure that its part of the security feature that was enforced on the system. But I do not know how to tweak it back to normal again. I'll gonna do some more testing first and let you know the results.

firewall filter. The reason: Just now I tried to use Apache Tomcat webserver and point to port 80, and I use the machinename, ITS WORKING FINE!! Tried to telnet to port 80 using the machine name, and of course it is working as well (using Tomcat). So, the question now is, where is the IIS setting that filter out the connection if using machinename? It must be somewhere. I'll let you guys know when I found it. But appreciate if you guys can help me too. :) Thanks.

not make sense. There is no such setting to filter out connections by machinename. Why? Because the machinename is not used to make a connection to IIS. The client does a DNS lookup on the machinename to obtain a IP-address, and then it makes a TCP/IP connection to port 80 of that IP-address using the HTTP protocol. IIS never sees the machinename, so how can it filter out such connections? Now, there is a documented XPSP2 security patch at the TCP/IP level which affects local-loopback connectivity via the IP-address associated with the machinename. It mainly affects NTLM Authentication, which is enabled on IIS but not Apache. I forget the exact patch# but I know it exists. And it has a Registry switch to disable that security behavior. Why it works for Tomcat server, not certain - maybe Java uses its own networking stack at the native layer. //David http://w3-4u.blogspot.com http://blogs.msdn.com/David.Wang // Ahmad A.

I think you are correct. And your explaination make sense. It must be at the NTLM authentication level or somewhere after TCP/IP receive the request, but bounced it back off. I know that Apache does not use NTLM and that makes the process is much simpler. I tried to uninstall and re-install IIS just now, and apparently, it is still not working. It must be somewhere in the registry. Somewhere in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa. Not sure which key, I'm afraid that I'll blow my whole operating system. As for the status, I copy this the console message: -------------------------------------------------------------------------------- D:\Documents and Settings\Ahmad>telnet rahman 80 Connecting To rahman...Could not open connection to the host, on port 80: Connec t failed D:\Documents and Settings\Ahmad>telnet rahman 25 D:\Documents and Settings\Ahmad>telnet localhost 25 220 rahman Microsoft ESMTP MAIL Service, Version: 6.0.2600.2180 ready at Wed, 2 9 Nov 2006 21:45:44 +0800 QUIT 221 Closing connection. Good bye. Connection to host lost. D:\Documents and Settings\Ahmad> -------------------------------------------------------------------------------- Telnet to port 25 is also not successful if using machinename. The journey will continue for me. But It's weird. Am I alone affected by this weird problem? Anyone out there has got this kind of mess? Thanks.

There is no such setting to filter out connections by machinename. Why? Because the machinename is not used to make a connection to IIS.
