I get the above error when I try to run my project.  Any ideas
what the configuration of the computer needs to be in order to run
VS2005's local web server?

Ok, the problem is that I apparently don't have the executable on my
machine.  Does anyone know how I can reinstall this
executable?  I've tried to repair my .NET studio installation, but
no luck.

I got same proplem , did you solve it ?

Thanks

I accidentally hit my firewall program to block the web server application.  When I figured out that it had to be that - after hours - I permitted the application and worked fine.  Maybe try todisable the firewall and try to run it. 
2 wrongs don't make a right - but three lefts do

hi,Echo88,
the same problem happened to me,  and i solved it using the same method.
appreciate your help.
struggling for ever

WebDev.WebServer.exe file is probably corrupted. Copy this file from another machine running vs2005 and  replace the corrupt copy on your machine. Otherwise reinstall.

WebDev.WebServer.exe can be found in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

**************************************************
Unable to connect to Visual Studio's Localhost Web Server
**************************************************
Here is the solution below. Check it.
************************************************** The Visual Studio's
localhost Web Server (or) Default Web Server is the file
"WebDev.WebServer.exe". You can find it in the folder
"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727" for Windows
xp/2000/2003 (OR) in "C:\WINNT\Microsoft.NET\Framework\v2.0.50727" for
Windows NT Servers.



Check out whether this file exists in your framework folder to verify
whether it was accidentally deleted. If it is not there, try to get a
copy of this file from any another system which contains vs2005
installed and paste it the frameworks folder of your system.



Keep a backup of this file "WebDev.WebServer.exe".



Note: "WebDev.WebServer.exe" does not come with dotnet framework but
with Visual Web Developer which is part of Visual Studio. Since it is
in the framework's folder, dont' think that it came with dotnet
framework file "dotnetfx20.exe".



If not solved.

Try to end any previous instances of WebDev.WebServer.exe still running using Task Manager. 

(or)

Host your web application manually using WebDev.WebServer.exe. Type
WebDev.WebServer.exe/? in Command Prompt (before doing this you to
change the directory to framework folder or add the framework folder to
PATH in console.

The syntax is : WebDev.WebServer.EXE /path:$rpath /port:$port /vpath:$vpath

Where path is for physical path location of your application's root
directory, port is the port number your application uses, you can
assign any free or unused port number and vpath is the virtual
directory name for your application's root directory

Example: WebDev.WebServer.exe /path:f:\myprojects\webapps\website1
/port:1036 /vpath:website1 (physical path and virtual path need not be
same as in this case 'website1')

Now you will see the icon in the tray which you usually see when you run a webapplication from visual studio ide.

and now you can accesss your application from any browser by simply typing for the above example as

http://localhost:1036/website1

Note: Here instead of localhost you can use your computer fullname.

(or)

Try this: In the frame work folder 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727' Run the following files..

'aspnet_regiis -i' : to register asp.net with Internet Information Server (IIS) and

'iisreset' : to restart IIS



If the problem still exists try to call me om my mobile.

sorry guys, maybe an old story, but i just had the same problem and loked around. 
I am running Visual studio 2008 professional and tried Microsoft Visual Web Developer 2008 Express Edition - just for fun and evaluation - then suddently my VS2008 stopped connecting to localhost developer web server when testing my projects. After a vhile i was lucky to solve it in 5 minutes - maybe som one could use my experience. 
- when testing a webapplication i tried to substitute localhost with 127.0.0.1 - then things worked again 
- 'ping localhost' showed me that localhost did not longer point to loopback adress 127.0.0.1 - don't know why
- edited the file 'hosts' in \%systemrpoot%\system32\drivers\etc\ (i don't have my own DNS server so i do static hostmappings)
- corrected the corrupt localhost entry to: 127.0.0.1 localhost
thats all - works fine again, no need for reinstalling and so on
hope u can use it - /Kim Steffensen
  
 
   

THNX!
It helped.

Commented
out the line
::1
         LocalHost

with
a # in the hosts file and it now works.
or
remove the next line in the windows host file
C:\Windows\System32\drivers\etc\hosts
::1
 localhost
This
is an IpV6 entry. Put a # in front of it. "
Instead
of commenting this IpV6 entry adding the following IpV4 entry above
this line also helps:
127.0.0.1
  localhost
