Ki,
Thank you. I solved the problem. We can't have administrator rights in our individual accounts on the domain, so we have a special administrator account that is only valid for a short time that we have to log into for starting Code Composer. My shares exist on my personal account, but not the administrator user account. Therefore, if I run as a different user (administrator) in Windows 7, these shares don't show up or are accessible.
Thanks for your help. The solution is to try to get my personal account administrative privs.
