Delphi Service Application and FileExists(FileName) over network

Posted on 2003-10-23
Last Modified: 2007-12-19

I have a drive mapping to my Novell Netware Server and are able to locate a file and get the Date and Time stamp information from it using FileDateToDateTime(AFileHandle).

This works 100% With a plain Delphi Application , but for some reason or the other I cant seem to get it to work with a Service Aplication.

I looked at the different options in the Services applet regarding login  because I thought the ServiceApp might not have enough rights. This did not solve my problem.

I did a test between a brand new serivce app and a traditional application and FileExists returns True in the Application but the service App returns false.

I pass a UNC path to the function, Like : \\\sys\public\TheFile.html

Any reason WHY this does not work in a Service App.

Any pointers or Information would be greatly appreciated.

Services usually log on using Local System Account which has no network rights. Make your service log on under your account, for example, and try again (stop it first !). Select the service and change its properties 'Log On' tab.

Well, I stopped the service app, gave it the login details of my administrator account, restarted and I stil get the same results ??

Any other Ideas. Maybe someone can confirm my findings or point out a mistake on my side.

Thanks in advance

You said that the same Delphi code worked well in a plain app but not in a service app. This definately means that you have a security issue (there is no problem in your Delphi code). For some reason your service can't login correctly (or is using a wrong account) and can't be authenticated against the server (computer Did you use the same account for your service as you were logging interactively? Perhaps you've used the local administrator account (your workstation administrator) which is not defined on the server.

Hello Geo

Regarding Authentication, I am logged into that server ( via my Novell client. So I need to make sure that my service Application logs in with my Novell E-Directory details and not my Local system administrator.

Will try that shortly and let you know...
