Unexpected Error 0x8ffe2740

System throws "Unexpected Error 0x8ffe2740 occured.", when i trying to start IIS. This kind of error will occur when there is a port conflict.

IIS is configured with the port number 80.


The following command will help to find the port usage,


netstat -anop TCP|find ":80 "

In the result file look if port 80 is LISTENING. If so, another program is using port 80.


Solution:
1.Close the Application, which is using the port no #### (port number 80 in my case)


Information:
In my case 'SKYPE' was causing the problem; In the Skype options i found: 'Connection: use port 80 as an alternative.'


After closed the skype, I Started IIS, It works.

Unable to Access IIS components

Today, One of My friend, Trying to deploy Webservice in local Webserver, but Throws the following Error!

you must install the following IIS components:

IIS 6 Metabase and IIS 6 Configuration Compatibility
ASP.NET
Windows Authentication

For more information, press F1.

But He installed IIS in his PC, but still it says the same error.

Note : If you are not installed, then follow the steps given in my previous post, How to Install IIS in Vista & Windows 7

If you are using other Other Operating System, then follow the manual.

After Installed IIS, We tried many times to publish the Web service, but still we faced the same issue, finally we come to know, My friend doesn't have proper priviledge to deploy to IIS. If you want publish on IIS, you should have admin rights.

So We run Visual studio thru "Run as administrator", then we tried to deploy the Web service.

Wow ... It works Well!

Hope it Helps you, if face the same problem!

Running ASP.NET IIS Registration Tool (Aspnet_regiis.exe) using Vista IIS 7

Today I tried running “ASP.NET IIS Registration Tool (Aspnet_regiis.exe)” in my laptop, which is using Vista IIS 7, by following command in command prompt (start->run->cmd)

C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50727\\aspnet_regiis –i

It gives the following error,

An error has occurred: 0x800702e4 The requested operation requires elevation.

Then I found that, vista is having tight security model. It won’t allow anything to run easily, also The ASP.NET IIS Registration Tool (Aspnet_regiis.exe) allows an administrator to install this.

Solution:

I opened the command prompt with administrator access by

Start -> All Programs -> Accessories -> Command Prompt -> right click -> run as administrator

Then I run the same command, it works fine.

I just want to share this solution here, so that it may help someone.

Have a great day!
