If you try to start or restart the World Wide Web Publishing Service on a Windows Server 2003 system with IISĀ 6 and you get this error, here is the fix for it.
"Could not start the World Wide Web Publishing Service service on Local Computer.
Error 1363: Cannot start a new logon session with an ID that is already in use."
Open a command prompt and type this command:
regsvr32 qmgr.dll
Now reboot the server and the problem is fixed. In our case, this happened after virtualizing a server and using a different NIC after it had been virtualized.
