The Name "Groupname" Is Not a Valid User or Group

When you attempt to add a group name to permissions by using FrontPage, the following error message occurs: If you have added the group name to the permissions through Windows NT Explorer, the group name appears only partially in FrontPage, up to the forward slash ( / ) or semicolon ( ; ). Attempting to remove it through FrontPage fails with no error in the client. When you reopen the permissions dialog, it is still listed.

In the Event Viewer, the following error messages occur: and

This occurs when the group name contains a forward slash ( / ) or semicolon ( ; ).

Group names can include any characters other than a backslash ( \ ), forward slash ( / ), or semicolon ( ; ).

To remove a group name that has been added through Windows NT Explorer, do the following:

1. Click Start and point to Run.
2. In the Open: dialog box, type "cmd" (without the quotation marks).
3. Change the directory (cd) to the folder above the Web content (for example, Inetpub).
4. Type "cacls foldername /t /e /r groupname" (without the quotation marks), where foldername is the name of the folder containing the content and groupname is the name of the group you want to remove.
   
   Note: This does not affect any permissions except for the group being removed; all custom permissions will remain intact.

The group should now be absent from the list in FrontPage.

Windows NT allows you to create groups with any character except a backslash ( \ ). FrontPage cannot read groups meeting the above conditions.
