I have a customer who uses thin clients to launch Terminal server desktop sessions. Then from inside the Desktop session they launch the Xenapp Web client to connect to our application. On last thursday The drive mapping stopped working. I know we didn not change anything on this end an they are claiming they didnt change anything. I cannot find out why the drives no longer map. The users DO have access to the servers C:\drive. I have verified this, but it simply will no longer map. The Terminal server they connet to for desktop sessions is Server 2003 Standard. SP2. Jason
