The server cannot load the application '/lm/w3svc '. The error is 'the specified metadata cannot be found. '.

View the information on the network and find that it is related to the DTs service.
Enter the command "services. MSC ", looking for the DTC service (full name: Distributed Transaction Coordinator), found that the Service list does not have this service, go to c: \ windows \ system32 to find the MSDTC directory, in addition, wamreg.dlland asptxn.dllare available in c: \ windows \ system32 \ inetsrv, and msdtc.exe is also available in system32. it seems that the MSDTC Service is not installed.

Run the command to install MSDTC-install
Run services. MSC and find that the DTC service is already in the list. set it to "automatic" and start it.
Make sure that the MSDTC Service has been started properly in the Event Viewer. [This step is critical. If not, restart your computer.]
The following command can be run only after MSDTC is started. Otherwise, the command will fail.
Cd % WINDIR % \ system32 \ inetsrv
Rundll32 wamreg. dll, createiispackage

Regsvr32 asptxn. dll

(Note that createiispackage is case sensitive .)

At this time, refresh the ASPX page to be run. That's great. It can be displayed normally !!

System. badimageformatexception: the format of the file 'gppbghost.exe 'is invalid

When you use installutil to install the service, the following error is prompted:

System. badimageformatexception: the format of the file 'gppbghost.exe 'is invalid

This problem is mainly caused by the version of installutil. If the called installutil version is 1.1, this problem occurs. If it is 2.0.50727, this problem can be solved. Therefore, you can manually call c: \ windows \ Microsoft. net \ framework \ v2.0.50727 \ installutil.exe or c: \ windows \ microsoft. net \ framework \ v1.1.4322 \ to C: \ WINDOWS \ Microsoft. net \ framework \ v2.0.50727 \

Common solutions:

The running method is as follows:
1. Start --> Run --> Enter cmd to run
2. After opening the DOS window, enter the above folder in the DOS window
3. Enter aspnet_regiis.exe-I-enable

 

 

 

However, this does not solve my problem. After many times, Google found that it was indeed caused by permission issues.

Solution:

Switch cmd to the system directory. The following example uses the system installed in c: \ windows.

Run cmd

CD to directory

C: \ widows \ Microsoft. NET \ framework \ v2.0.50727

Input

Aspnet_regiis-ga ASPnet

Get the prompt.
