Addition to my previous post: when I create a new folder on the desktop, it is owned by "Administrators" (plural) and the group is Domain Users.  It has no permissions:

cygwin$ ls -l ~/Desktop
d---------+ 2 Administrators Domain Users     0 Apr 12 10:19 New folder

cygwin$ ls -lad ~/Desktop/
drwxrwxrwx+ 6 annius Domain Users 12288 Apr 12 10:19 /home/annius/Desktop/

(permissions 777 set on Desktop is probably due to one of my previous attempts to get full ownership of the files on my desktop).

I am not sure what I am experienced has anything to do with UAC, but I suspect it does.

I am logged in as a regular user ("annius") and I am in the administrators group.  When I create a folder in my Documents folder, it is owned by "annius" as I would expect.  When I create a folder on the desktop, it ends up owned by "Administrator" (I don't need to answer any prompts to get it owned by Administrator).  Subsequently, I can't rename it or put anything inside it.

Could this be because I once "elevated" and as of that moment I my Windows explorer runs as "Administrator"?

This happens regardless of whether I have UAC enabled or disabled.

The only thing that is special is that this happens on a laptop machine that operates inside the windows domain at work when I am at work, then I put it to sleep, and take it out of sleep at home where the domain "is not there".  Again, not sure that that has anything to do with the problem.
