Vs2003 prompt: An error occurred while trying to run the project: Debugging cannot be started on the Web server. ASP. net or ATL server debugging. verify that ASP is correctly installed on the server. net or ATL Server Solution

My sub-configuration is: the operating system is win2003, and the first installation platform is vs2005 ,. net2.0 is installed due to project needs. net1.1. The platform uses vs2003. When running a project, the system reports an error:

The process "[3940] w3wp.exe" automatically appended to the computer "softserver" failed, and later found that the cause was. net2.0 and. net1.1 conflict. The default Asp.net version in the Asp.net tab of IIS is 2.0, and no 1.1

Solution:

You need to re-register ASP. NET in IIS and run in MS-DOS:

C: "Windows" Microsoft. net "Framework" v1.1.4322 "aspnet_regiis.exe-I or Microsoft Visual Studio in the program. NET 2003-> Visual Studio.. Net tool-> Visual Studio. NET 2003 command prompt execute aspnet_regiis.exe-I

After the fix is successful, you can enter the. NET version 1.1 in IIS.

Select the Asp.net version in the Asp.net tab of IIS. The default value is 1.1.

The error message indicating that the process "[3940] w3wp.exe" automatically appended to the computer "softserver" fails to exist.

After the solution, a new problem occurs, prompting:

An error occurred while trying to run the project: failed to start debugging on the Web server. Failed to start ASP. Net or ATL server debugging. Verify that ASP. Net or ATL server is correctly installed on the server

Solution:

In IIS, there are two web service extensions: Asp. netv1.1.4322 and ASP. the netv2.0.50727 option is originally ASP. netv2.0.50727 has been enabled, whereas ASP. netv1.1.4322 is forbidden. The reason is found,

The ASP. netv1.1.4322 status is changed to the allowed status.

The problem has been solved !!!!
