I have two servers running Windows Server 2003, and I want copy files from one server (A), programmatically with a windows service running under the Local System account, to a shared folder on the other (B). I keep getting "access denied" errors, and I can't figure out what security settings I need to set to open the shared folder for writing.

This is what I've done on the recieving end:

1. On A, right-click on the folder to share, choose the tab "Sharing" and select "Share this folder". Set a share name.
2. Click "Permissions", add the group "Everyone" and give it full control.

I tried choosing the "Security" tab to give some permissions there as well, but the "Add" dialog only finds local users, despite the fact that B shows up in the "Workgroup computers" dialog. After further inspection, this is the case also for the "Permissions" dialog under the "Sharing" tab (are they the same?).
