I’m not going to bore you with a great deal of information about shared folders, because most of it remains the same as in NT 4.0. However, the important stuff you need to know:
Hidden administrative shares still exist, such as C$, D$, Admin$, and so forth. Only someone with administrator-level privileges can use these.
Share permissions have changed. They now follow the same Allow / Deny format as NTFS permissions, and are limited to Full Control, Change, and Read. The effect of these is cumulative, so if you were given Read and Change, your effective share permission would be Change. A denied permission always overrides one that has been allowed.
In the same manner as NT 4, when both shared folder and NTFS permissions are used, your effective permission becomes the more restrictive of the two.
Connecting to a shared folder can still be done in all the familiar ways, including mapping a drive, connecting to a UNC path, or browsing the network. A couple of quick notes here:
It is not called Network Neighborhood anymore – now My Network Places. Most of the changes here are cosmetic, but you can also use the tool to browse Active Directory.
One new option is the Add Network Place wizard. This wizard will allow you to create a shortcut within My Network Places to things like Web Folders, FTP sites and internal servers, while providing for things like a saved username for external resources.
