Network Specialist to create a drive to map to.

We currently have a dedicated server that works on a linux platform I believe we have the drive mapped through ftp it does not work so well. All we are trying to do is some how have a fully functional drive that we can use as a common drive where emplyees can store files on.. The dirve we have now works however it makes it though we can not drop or drag files and so fourth. Its is a dedicated webserver that we have.
