Windows Service startup error

[niclarke]

I have created a windows service based on a walkthrough in the MSDN
library
(ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VisualStudio.v80.en/dv_radcon/html/e24d8a3d-edc6-485c-b6e0-5672d91fb607.htm
- Creating a Windows Service Application in the Component Designer)

But when I start the service I get a Unhandled
System.Security.SecurityException and then the Error: 1053 popup.

If I'm quick with the debugger I get an exception on:

if (!System.Diagnostics.EventLog.SourceExists("MySour ce")){

of:

System.Security.SecurityException was unhandled
Message="The source was not found, but some or all event logs could
not be searched. Inaccessible logs: Security."
Source="System"
StackTrace:
at System.Diagnostics.EventLog.FindSourceRegistration (String
source, String machineName, Boolean readOnly)
at System.Diagnostics.EventLog.SourceExists(String source,
String machineName)
at System.Diagnostics.EventLog.SourceExists(String source)
at MyNewService.MyNewService..ctor()
at MyNewService.MyNewService.Main()

Any ideas what is causing this? and/or how to fix it.

Cheers,
Nick
