In our office, we have a networked hard drive tower, called "Drobo" that is used for sharing files and allows read/write permissions for folders and users. There are 6 computers in the office and only one user per computer. Each has their own username and password. Seeing the Drobo and connecting with a username and password works for the Mac users, but as soon as a Windows XP user has to log in to access folders, the system returns error messages that folders are already opened by other users. I have spent many hours trouble shooting with the "Drobo" support team and they insist it is a Windows problem. Here is the error message I receive and the one following it thereafter whenever I try to log in to folders on the "Drobo" networked hard drive on the Windows XP machines: 1) The network folder specified is currently mapped using a different user name and password. To connect using a different username and password, first disconnect any existing mappings to this network share. 2)The mapped network drive could not be created because the following error has occurred: multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again. Your advice most appreciated. Thanks very much.
