If Simple File Sharing is enabled please disable it and tell me if that resolves the problem.
To disable simple file sharing yourself, follow these steps:
- Click Start, and then click My Computer.
- On the Tools menu, click Folder Options.
- Click the View tab.
- In the Advanced Settings section, click to clear the Use simple file sharing (Recommended) check box.
- Click OK.
So SFS was enabled but you disabled it and still no success?
Does the error reference anything about 'File and Print Sharing' at the bottom?
Can you email us the entire error?
