Change File Permissions On Multiple Folders

I've got a file structure similar to the following.  Each line below represents a subfolder:

Project
    Folder1
       Folder1a

This structure exists for several hundred projects.  I want to change the file permissions on the "folder1a", but I don't want to go to each individual folder if possible.  The new permissions would be identical for all of the projects.

Is there a utility (or something built-in to Windows) to allow me to select all (or at least several) of the folders at once and set the permissions?

The file system is Windows Server 2003.

Thanks!

Use the CACLS or XCACLS command to set permissions from the command line, in conjunction with FOR to loop through folders. CACLS is readily available in 2003, XCACLS is the extended version. Free download here: http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/xcacls-o.asp

The for loop does this (these commands are not harmful, they don't change anything because of the ECHO statement):

D:\Fileserver\Projects> for /D %f in (*.*) do @echo "%f"

/D loops through folders only, not files. %f is replaced with the folder name and should be between "" if it contains spaces.
Here you get the idea of FOR. Then have a look at the CACLS command line (CACLS /?). The end command goes something like this (leave the echo out):

D:\Fileserver\Projects> for /D %f in (*.*) do @echo cacls "%f\Folder1\Folder1a" /G UserGroup:C /E

Test this on a veryveryvery unimportant test copy of your data so you know what it does... but this is a very powerful command, and you can even nest for loops for the really complex stuff.

Rant32,

Thanks for the quick and certainly detailed answer.  I feel like I've got a potential nuclear device in my hands now, but I will heed your advice and thoroughly test on something non-production.

Very useful, or very destructive, indeed.
