I'm having a constant issue when I start up my computer here at work, where I can't access items on my desktop (my domain account). The icons are faded and have a white X in the bottom right corner, and not all of them are visible on the desktop. After a while, the problem seems to correct itself, but it's still an issue.
For information, we have accounts set up through AD to make both My Documents and the Desktop folder be associated to domain accounts, which are held on a server and made accessible through DFS (in other words, the actual location of the Desktop and My Documents is \\fs1\dfs\useraccounts\*username*). We never had this issue with Windows XP.
