I have a network with 10 work stations and a single Windows 2003 Server standard, which also runs Exchange 2003 and SQL Express. Suddenly, one of my users can't connect to a mapped network drive or network printers. I deleted the printers and tried to add them again, but they do not appear on the Active Directory list when I search for them. I disconnected the mapped drive and tried to map it again, but when I browsed to the server and tried to expand the list, it would not show the network shares. I was able to successfully do these tasks when logged on as administrator. It is only the one user who is having the problem. Her Outlook 2007 is still able to connect to Exchange and database software is able to access the SQL database on the server. There have been no changes to this user's security permissions.
