On page 41 of Beginning ASP.NET with VB.Net it provides instructions to configure directory security. I think this example was created using windows 2000.

The problem is that I am using win XP Proffessional, and when I try and alter my directory security there is no security tab. I've tried selecting the properties while in IIS, from the actual folder, from its shorcut and right clicking and selecting 'sharing and security' but none of these have given me the properties that look similar to the example on page 41.

Can anyone tell me how i can change my security setting?

P.S. i have altered all paths so that they correspond to my directories.

These are the errors i receive when trying to access the page.

The ASP.NET process is not authorized to access the requested resource. For security reasons the default ASP.NET process identity is '{machinename}\ASPNET', which has limited privileges. Consider granting access rights to the resource to the ASP.NET process identity.

To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the "{machinename}\ASPNET" user. Highlight the ASP.NET account, and check the Write box in the Allow column.

PROBLEM SOLVED:

Troubleshooting
If the Security tab is not available and you cannot configure special permissions for users and groups:
· The file or folder to which you want to apply special permissions is not on an NTFS file system drive. You can set permissions only on drives that are formatted to use the NTFS file system.
· Simple file sharing is enabled. By default, simplified sharing is enabled in Windows XP unless you are on a domain. To work around this behavior, disable simplified sharing.

SUMMARY
This article describes how to disable simplified sharing. Note that you cannot disable simplified sharing in Microsoft Windows XP Home Edition.

By default, simplified sharing is enabled on a Windows XP-based computer if the computer is not a member of a domain. Simplified sharing lets you easily share folders with everyone on your workgroup or network and make folders in your user profile private. However, if simplified sharing is enabled, you cannot prevent specific users and groups from gaining access to your shared folders. If you disable simplified sharing, you can allow specific users and groups to gain access to a shared folder; those users must provide a password to gain access to your shared folder.

If simplified file sharing is enabled, you see the Simple File Sharing user interface rather than the classic Security and Sharing tabs. This new user interface is implemented by default in Windows XP Home Edition and Windows XP Professional if you are working in a workgroup. If you disable simplified sharing, the classic Security and Sharing tabs appear and you can specify which users and groups have access to shared folders on your computer.

NOTE: Security can be set only on a partition that uses the NTFS file system. If you remove the Everyone group from the NTFS permissions, the file or folder is inaccessible over the network.
