cannot run sfc /scannow, can not backup, unable to remove features from SBS 2011 (server 2008 R2 based)

I am unable to backup the server, unable to remove backup feature, unable to run SFC /scannow.

This is SBS 2011 machine. I dont have any current backup. Have to fix this machine.

Have done chkdsk. No errors found.

Error: Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

The Server Manager throws this error when I try remove feature.

C:\Windows\system32>sfc /scannow

Windows Resource Protection could not start the repair service.

It sounds like that server has been breached .  I would boot from the SBS Installation CD and select Windows repair.

Here is a page on Microsoft's site that will provide repair information for multiple aspects of that serevr.

hope this helps!

Thanks all for responding
When i try to repair sbs 2011 it says version mismatch.  This media is the original one by which i installed the sbs two years back.

I guess its due to service packs i might have installed over the period of time.

Where to find the compatible repair media.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

With no backup and a DVD what won't work, It looks like you only have these options left:

1. Create a Slipstream DVD with the service packs and retry the Windows Repair
2. Call Microsoft supt and open a case
3. Boot with a Windows PE DVD, backup all your data, rebuild your server and restore the data.

Hope this helps!

Sorry for the delayed response.

I visited the site personally. I was astonished to see that very frequent power failure.
No battery backup was there.
Server was rebooting continously many times a day due to power.

I found a backup that was too old. While troubleshooting & reconfiguring the windows image backup, that backup was also screwed up. Though the vxd was there in the backup folder by which we may extract files but can not restore bootable OS & application.

Finally, I copied all the required current data from the server & reformatting the SBS. Luckily only 7 windows client are there attached with the server.

Thanks for the support.
