EXE Files missing on OS Partition SBS 2008

Hi

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.

If nothing is affected it has to be an issue with what you are viewing or the explorer shell?
Just as a test can you: Start>Run in search bar> open run and type cmd. Does the command prompt come up?

Hi

All cmd's seem to work correctly. CMD, ipconfig, eventvwr, services, gpedit, etc

But when you click on any icon, it says the file is miising, when checking the folders there are no exe files.

If you did the test using the run command... the system must have found the cmd.exe file to start the command. Meaning it has to be a visual thing.
Please confirm you used the run command?


Try the following:
Click Start > Run > Regedit
Registry Windows will open.
Navigate to the registry folder HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
Double Click CheckedValue key and modify it to 1.
NOTE: Always back up your registry before editing anything in it.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Harddrive clone is still running, has 17 hours to go. I will then look at the registry and get back to you.

I use CTRL-R to open run cmd

Ok Means all exe files are still there.
You just have all exe's hidden.
Regedit should fix that.

Thanks for trying though. Had this happened during the week when more experts are online we might have found a solution

Re-installed SBS to "C" drive then ran restore successfully, customer will only lose 2 days of work. Unfortunately back happened at the time of the dissapearance of files so I am reluctant to try save the customer a day and then have to re-do the whole job.

Delivery in 16 hours
