How to have drawings open as read-only if someone is already using them

[Taalmankoch1]

We have just installed a few copies of AutoCAD LT and have run into a new problem - when one person has a file open, if another person opens it it does not give us a read-only option - both users can open & edit the same file simultaneously. How do we prevent that? We are running LT 2010 on macs using windows XP installed with VMWare fushion and a mac server for file sharing. We did not have this problem with AutoCAD 2005... thanks for any ideas!

VMWare fusion is a hosted operating system environment and is not a supported environment for Autodesk products.
See technical solution Autodesk software and hosted operating system environments

AutoCAD LT 2010 and 2011 are supported on a Macintosh computer through Parallels Desktop, Autodesk’s preferred Mac virtualization software, or by using Apple’s Boot Camp feature.
AutoCAD LT can be used on the Mac via Parallel Desktop for Mac without having to boot directly into the Windows OS, so it is easy to switch between platforms.
With Boot Camp, you can install AutoCAD LT on a Mac computer on a Windows partition.
The system must use Boot Camp to manage a dual OS configuration and meet the minimum system requirements.
This is explained in detail in the document AutoCAD LT 2011 Questions and Answers.
