InDesign CS6 crashes on a server-client network

Hello Experts,
I am facing a problem with the InDesign CS6 software installed on my client and server network. I am running Mac OS X 10.8.2 on my server and windows 7 on my client. InDesign works perfectly on my Mac but with the windows 7 client, InDesign crashes soon after opening an existing file from server or creating a new file and saving it to the server. It gives an error message stating that the network connection was lost for file or that the file is being modified by another process. I get this error both when logged in as guest or as administrator. I tried turning on file sharing on my Mac OS X Server and installed a fresh version of InDesign CS6 trial. But I still get this error few minutes after opening a file from server. I have no more ideas left to try. Can someone here please help to find a fix for this issue? Thanks a lot.

The network connection was lost for the file \MINTVPublic/testUntitled-1.indd, or the file was modified by another process.
