I have a customer running SBS 2008 64bit.
There are 3 partitions:
1. “C Drive” contains OS and other installed programs
2. “E Drive” contains Exchange
3. “F Drive” contains all data folders as well as some programs installed there.
They have a 2nd machine running SBS 2003 as a SQL Server.
Last night at approximately 23H30 every exe file on the C Drive disappeared. No other files seem to be affected nor are any files missing in the other partitions. The SQL server and ±30 user pc’s are completely unaffected.
Restore from backup was unsuccessful as it did not see a MS installation. I am now reloading the server and will then restore from the backups.
My question is this: any ideas as to what may have caused this and what we can do to prevent a re-occurrence.
