Service Logon Only Works As Administrator

Thanks for trying - tried it.  No luck, it told me that it was add "logon as a service" to the new/copied user but get the same error when it tries to logon.

HI - the COM object that is being run by the service is Visual Fox Pro 9 COM Server (exe).  The error I get references the OnStart method of the COM object where database opens and writes are taking place to the server that the service is running on.  I've double-checked those directories to be sure that the Administrators group has Full Control on each and they do.

I implemented the advice of a previous post so that now the ServiceLogonUser belongs to the Administrators, Domain Admins, Domain Users, Enterprise Admins, Group Policy Creator Owners and Schema Admins - groups.

A later method in the COM server also reads and renames files on another 2003 server outside of it's domain.  I tried adding Modify permissions to the file directories on that machine for Enterprise Admins of the home domain (the domain where the service is running).  Could this be the area of the problem?  The home Administrator still works and the new ServiceLogonUser doesn't.

My guess is that this line is where you might be having problems ... "where database opens and writes are taking place "  ... How are you connecting to the database?  My guess is that something is trying to use the account that is running the code to conenct to the database and it cannot do that now.

So I've taken out ALL logic out of the COM object.  Even the HELPSTRINGs, even tried taking out the lines that I think were critical:

SYS(2335, 0)
SYS(2340, 1)

And same error with ServiceLogonUser and fine with Administrator.  The only things in the object are PROCEDURE names, RETURN, ENDPROC lines.  Same problem.  Interestingly, taking out the 4 variable definitions 'myvar1=0' lines at the top create memory violations when missing (I'm guessing I'd need to re-register the COM object to get rid of these).

I"m wondering if the C# logic in the installer class needs more for non-Administrator users:

            this.serviceProcessInstaller1.Account =  ServiceAccount.NetworkService;
            this.serviceProcessInstaller1.Username = "";
            this.serviceProcessInstaller1.Password = "";

Any help is greatly appreciated!  Do we know for sure that Windows Server 2003 supports user defined logon names?

Any success with this?
I was thinking baout this and it could very well be a permissions issue with the COM object or something along those lines ... i ran into problems a while back where permissions for executing code were removed from some of my IIS servers.
