The configuration section cannot contain a CDATA or text element in SMSvcHost.exe.config

Question

I can't start the windows service "SMSvcHost" on my Windows 7 desktop. Here is the error message from the event log:

A request to start the service failed.

 </configuration>

What is wrong?

Answer 1

Okay, I just found the answer. Something like:

<allowAccounts>
            <!-- LocalSystem account -->
            <add securityIdentifier="S-1-5-18"/>
