In Windows XP, you must enable the Security Tab display for folders. The security tab is not visible by default. To do this, Log in as the Administrator. Select Control Panel-Folder Options, and click on the View tab. Under Advanced Settings, deselect the “Use Simple File Sharing” option. Click OK. As Administrator, the security tab is now available for the folders. Right-click the Windows4D folder, and select Properties. Click on the Security tab. Check the “Allow” box for Full Control for the appropriate user(s). Click OK. The client will now be able to connect to the server without error.
