Woohoo! I have stumped Apple!!! Since the upgrade to Lion at work I cannot access random network folders through my desktop shortcuts. The folders are even in the same directory. Four work, two don't. I connect to the server just fine. Through software - such as attaching a file to an email in Outlook or browsing my files in Adobe Bridge - I can access all network folders without a problem. I even checked by launching Parallels and logging into the network there. Once again, no problem. I just can't do it through my desktop and Finder. I have a senior engineer calling me in a couple of days.
