Saw a similar thread Since upgrading Windows backup fails at http://answers.microsoft.com/en-us/windows/forum/windows8_1-system/since-upgrading-windows-backup-fails-cryptographic/aee23306-09df-4182-a549-da1084e20513 and followed the advice there and didn't have issues. There was a link to EventID 513 Capi2 error at http://social.technet.microsoft.com/Forums/windows/en-US/14abbc90-cab5-4fc6-953a-96c1929f9a7b/eventid-513-capi2-error?forum=itprovistasp which goes back to 2009 slightly before Windows 8.1. In any event this article (which I only glanced at) suggest checking 1409 files for errors.

Is this problem another of the newly introduced Windows 8.1 bugs or ishere a solution that can be applied? Thanks.

Hope I can help to someone.

I had the same issue with the fresh Windows 8.1 Pro.

Couldn't find answer so had to debug Windows to find a solution.

"Microsoft Link-Layer Discovery Protocol" binary is \Windows\system32\DRIVERS\mslldp.sys

Its config registry key is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MsLldp

During backup a VSS process running under NETWORK_SERVICE account calls cryptcatsvc!CSystemWriter::AddLegacyDriverFiles(), which enumerates all the drivers records in Service Control Manager database and tries opening each one of them. , The function fails on MSLLDP record with "Access Denied" error.

Turned out it fails because MSLLDP driver's security permissions do not allow NETWORK_SERVICE to access the driver record.

The binary security descriptor for the record is located here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MsLldp\Security

It should be modified, I used SC.EXE and Sysinternals' ACCESSCHK.EXE to fix it.

The original security descriptor looked like below:

>accesschk.exe -c mslldp

mslldp

  RW NT AUTHORITY\SYSTEM

  RW BUILTIN\Administrators

  RW S-1-5-32-549       <- these are server operators

  R  NT SERVICE\NlaSvc

No service account is allowed to access MSLLDP driver

The security descriptor for the drivers that were processed successfully looked this way:

>accesschk.exe -c mup

mup

  RW NT AUTHORITY\SYSTEM

  RW BUILTIN\Administrators

  R  NT AUTHORITY\INTERACTIVE

  R  NT AUTHORITY\SERVICE  <- this gives access to services

How to add access rights for NT AUTHORITY\SERVICE to MSLLDP service:

  1. Run: SC sdshow MSLLDP

You'll get something like below (SDDL language is documented on MSDN):

D:(D;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BG)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;SY)(A;;CCDCLCSWRPDTLOCRSDRCWDWO;;;BA)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;SO)(A;;LCRPWP;;;S-1-5-80-3141615172-2057878085-1754447212-2405740020-3916490453)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

  1. Run: SC sdshow MUP

You'll get:

D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

  1. Take NT AUTHORITY\ SERVICE entry, which is (A;;CCLCSWLOCRRC;;;SU) and add it to the original MSLLDP security descriptor properly, right before the last S:(AU... group.
  2. Apply the new security descriptor to MSLLDP service :

sc sdset MSLLDP D:(D;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BG)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;SY)(A;;CCDCLCSWRPDTLOCRSDRCWDWO;;;BA)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;SO)(A;;LCRPWP;;;S-1-5-80-3141615172-2057878085-1754447212-2405740020-3916490453)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

  1. Check the result:

>accesschk.exe -c mslldp

mslldp

  RW NT AUTHORITY\SYSTEM

  RW BUILTIN\Administrators

  RW S-1-5-32-549

  R  NT SERVICE\NlaSvc

  R  NT AUTHORITY\SERVICE

  1. Run you backup app, the error is gone for my Home Server backup.

!!! Do not forget to use your security descriptor for MSLLDP driver since I guess there can be some rare cases when its different for your machine. Do not copy my SDDL descriptions, just in case. And backup the old descriptor just in case !!!

I don't know what reason MS had behind all this, probably some security concerns or probably this is just a bug. Definitely not a security problem in my environment.

Good luck!

    On page 13 of this long thread on August 12, 2016, DPM 2009 suggested that the magic sc sdset MSLLDP command be put into a batch file.

    I did, and it worked beautifully last night on my Win 10 Pro 64-bit machine (Version 1607, OS Build 14393.222).  No more error messages on reboot.

    Between that DPM 2009 post on page 13 and here, there are many posts about aplha45's problems with an extra line.  As a result, I was unsure that the DPM 2009 post was still good and had to do a lot of checking to feel confident about it.

    Could DPM, Mark Waukesha and the other good brains here now re-post a short catch-up of what to do?  Would it even be possible to attach that single-line batch file?  Or maybe even add to it to make it open cmd to show the good results?

    Thanks to all for this good thread!

    Yours - indeed - is identical to mine, Alpha45. Therefore, I think there is nothing to cure. That extra string portion you've got appears to have had no effect at all. Are you satisfied?

    I did see one site that had a hint of a way to clear the extra string - but I hesitate to mention it.

    OK, I'm happy, but not satisfied, because I do not understand ......

    I wish I knew what to match the SID of the string, because I find no match anywhere, even in the registry ....

    Hello and thanks
