I have a windows service that I am trying to use to access a MOSS 2007 to set data in list , WHen my server attempts to access the same share I get an access denied error. On my local machine I can do everything but on our windows 2008 server it cannot. I can't get any other information other than 'access denied' so is there a way to get a more detailed error or trace what is happening? So again: In windows 2003 I can access the list windows service cannot On my local machine (XP) the service can access the share. that's general Exception I have : The description for Event ID ( 0 ) in Source ( Application ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event
