I used the following command during installation to set rights: ECHO. ECHO Setting File and Folder Permissions xcacls C:\PROGRA~1\Agent\Data /T /E /C /G Users:RC /Y However, when install completed, and I went to check the folder permissions, it would complain: "The permissions on Data are incorrectly ordered, which may cause some entries to be ineffective. Press OK to continue and sort the permissions correctly, or Cancel to reset the permissions." I found the following at MS: ACLs Are Incorrectly Ordered on Subfolders http://support.microsoft.com/default.aspx?...kb;en-us;322293 from the above link: RESOLUTION A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Windows XP service pack that contains this fix. To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. I believe Microsoft have a VBScript which will let you set the permissions without screwing up the order, but they won't let you download it. If anybody has other suggestions why this is going wrong for me, I'd be very much interested. Kind regards, eNuffSaid EDIT: I'm aware that I'm using XCACLS and not CACLS, but I've tried both and the outcome is the same.
