CANNOT access via http://localhost but CAN access via http://computername or DNS from the internet

So...

'http://server_ip_address/application' works locally

'http://dns_address/application' works locally

'http://computer_name/application' works locally

'http://localhost/application' does not work locally

Any ideas on getting localhost to work again? It does work for the browsing the root however.

This is IIS 7.5 and ASP.NET MVC 2 running in classic mode.

open this file c:\windows\system32\drivers\etc\hosts with the notepad and add the lines 

127.0.0.1       localhost

if it is commented (default, line start with ;) then uncomment it.

and try it again.

bad: (ipv6 problem)

C:\Users\Administrator.DEVJC>ping localhost

Pinging DEVJC.vaio.cl [::1] with 32 bytes of data:
Reply from ::1: time<1ms

Ping statistics for ::1:
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
     Minimum = 0ms, Maximum = 0ms, Average = 0ms
Control-C

good: (ipv6 and ipv4 compatible)

C:\Users\Administrator.DEVJC>ping localhost

Pinging DEVJC.vaio.cl [127.0.0.1] with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

Ping statistics for 127.0.0.1:
    Packets: Sent = 2, Received = 2, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

Microsoft says "# localhost name resolution is handled within DNS itself." but it is a lie (an half-lie). Sometimes is true but in a few cases it fail (or it try to resolve externally = slow)

You can also resolve by adding the Binding information in your IIS. To do this:

  1. Open IIS
  2. Select Default Web site
  3. On right side actions panel, select Bindings. You will get site bindings screen
  4. Add a new binding adding 'localhost' in the Host name field
  5. IP Addresses field can contain text 'All Unassigned'
  6. Then save and reset IIS

After this I think you should be able to browse all applications hosted in your IIS with localhost.

wait to TMG sync firewall. then go to your site and check your problem.

This is happening because I am only allowing SSL for the application which is enforced by a redirect mechanism to the SSL page AND the SSL only listens on the correct port.

Thanks for the help guys, I really appreciate it.
