OK . . . XP has been doing this cute trick where it keeps changing file and folder properties while we're not looking. It's doing this on a machine I'm hoping to replace this weekend anyway, but I'd still like to know WTF, just in case it ever happens again.
Its favorite thing to do is to make it so no one is allowed to rename, move, or delete files. It started by doing this in the Shared Folders directory, and now even logging in as the Administrator doesn't help. But now it's doing it to subdirectories (at random?) elsewhere, including in the regular login's My Documents folder.
The Help file for File Explorer tells me to open the Computer Management console, which is an interesting place to start, but, for one thing, where the heck is that console normally linked to? I can't find it to run it except from the dumb Help search page. Based on opening it and looking at Task Manager, I thought it was mmc.exe, but apparently not, or not quite, or something.
But, in any case, I can't figure out how to use it. The Help instructions say "In the console tree, click Shares." and it has a little tree that shows Shares in Shared Folders, but in the tree I actually get, there's only Sessions and Open Files, and even logged in as Administrator I don't have permission to see what those are.
Is this just another Windows thing that needs to be nuked from orbit? Because it's really, really annoying. Really.
