I have around 100 users sharing a network server with Windows Server 2003 that has a capacity of 206G. I come in this morning and the server was completely full. Ironically, I upgraded the server just 6 months ago from an older server that only had ~20G of space. Despite my protests apparently the users seem to think it is okay to put personal junk and business data that should really be stored on their local hard drives on the server. Is there a way I can limit the size of individual folders? For instance, the engineering department is currently using 80G of space, on a folder I have mapped out as the J drive. How can I limit the size of this folder to 40G? Also, within that folder there are subfolders, can I limit the space of specific subfolder to say 500MB?
