Missing 100 MB MS Access MDB

Hi Gurus,

I have important MS Access MDB with size 100 MB plus. It is saved on shared folder of Windows 2003 server.

It is missing and the user said he process it last night. My scheduled shadow copy is 7 AM this morning and the MDB is already missing.

Is there a way to restore the file?

IS there a way to trace who's the last user accessed it or deleted it?

Thank you and more power to Spiceworks.
