DescriptionAn attempt was made to register protocol '%1', however protocol '%1' is all ready being handled by another listener adapter. Therefore the registration was rejected. The data field contains the error number.
Event Information According to Microsoft :
Cause :
This event is logged when attempt was made to register protocol, however protocol is all ready being handled by another listener adapter.
Resolution :
Delete a duplicate listener adapter protocol
The listenerAdapters section in the ApplicationHost.config file defines the protocols with which the Windows Process Activation Service (WAS) binds.
Each listener adapter has a name attribute that contains the name of the protocol that the listener adapter processes. Only one listener adapter can be defined for each protocol, or WAS will be unable to process requests for the protocol that has the duplicate definition.
To fix this issue, find the duplicate protocol in the ApplicationHost.config configuration file and remove it.
To perform this procedure, you must have membership in Administrators , or you must have been delegated the appropriate authority.
To remove the duplicate listener adapter protocol:
1.Open an elevated Command Prompt window. Click Start , point to All Programs , click Accessories , right-click Command Prompt , and then click Run as administrator .
2.Type cd %Windir%\system32\inetsrv\config
3.Type notepad ApplicationHost.config
4.In notepad, search for the listenerAdapters section under system.applicationHost .
5.Remove the duplicate protocol.
6.Save the applicationHost.config file, and exit notepad.
Verify :
You can use an Internet browser to verify that a protocol adapter is functional by following these steps:
1.Select a Web site or application that is configured to respond to the protocol you want to verify.
2.In the address bar of your browser, type a protocol-specific request to the Web site or applications that you chose in step 1.
3.If the protocol adapter is working, your browser client should display the expected output page.
Note : If the protocol adapter is from a third party, refer to the documentation for the adapter. The documentation may have specific steps that explain how to verify the state of the service or process that hosts the protocol adapter.
