In Windows 2000, a global group name that contains more than 20 characters is invalid and cannot be created.

NOTE: Windows NT 4.0 allowed creation of invalid group names.

A global group can contain any uppercase or lowercase characters except the following:

<font size="+1"><b>"   /    \    \[    \]    :    ;    |    =    ,    +    *    ?    <    > </b></font> NOTE: A global group cannot consist only of periods and spaces.

A local group can contain up to 256 characters.

A local group can contain any uppercase or lowercase characters except the backslash (\).

NOTE: If you upgraded from Windows NT 4.0 and have groups that contain illegal characters or length, I would rename them.
