Windows Process Activation Service – Fixing Error 2 When Starting

I've had success with Sysinternals Process Explorer. With this, you can search to find what process(es) have a file open, and you can use it to close the handle(s) if you want. Of course, it is safer to close the whole process. Exercise caution and judgement.

To find a specific file, use the menu option Find->Find Handle or DLL... Type in part of the path to the file. The list of processes will appear below.

If you prefer command line, Sysinternals suite includes command line tool Handle, that lists open handles.

Examples

• c:\Program Files\SysinternalsSuite>handle.exe |findstr /i "e:\" (finds all files opened from drive e:\"
• c:\Program Files\SysinternalsSuite>handle.exe |findstr /i "file-or-path-in-question"

The event id 7023 and error message The World Wide Web Publishing Service service terminated with the following error: The parameter is incorrect (shown in your screenshot) lead to http://support.microsoft.com/kb/327649 which suggests the port range needs to be increased, and gives details of how to do it by either deleting the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc or changing values underneath it. But before you change anything, remember the usual reason for specifying these values is so you know which ports to allow through firewalls, so remember to make the corresponding network changes.
