[Any connection between KART 5 (3660) and BSOD Critical Service Failed]

i checked my servers in regarding this key (UpperFilters). It is not present on the one with the empty catroot folder and it is not present on the other servers (i everywhere uninstalled KART but did not yet restart the servers).

Do i have to create this key ? is there a regfile file which does the work ?

 

This key is required for most backup programs and system restore to work so YES you should create it.  I will paste the text below so you can create a regfile for it. open Notepad, copy/paste and save as *.reg

 

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71a27cdd-812a-11d0-bec7-08002be2092f}]
"UpperFilters"=hex(7):76,00,6f,00,6c,00,73,00,6e,00,61,00,70,00,00,00,00,00

Hi, about that registry fix, if it could help: 

I was not able to add the key in that way (it did not work, ie no key added), so I added it manually: new “Multi-String Value” named “UpperFilters”, with value “volsnap”, restart the server.

Thank You for your solution, following your steps solved my BSoD problem (Kaspersky antiransomware was the culprit) on my Windows Server 2016, thank You a lot.👏

I have only a question: did You find the shadow copy service not working? ie, if I right click on my C disk… Shadow Copies tab… blank with “NO VOLUME IS ELIGIBLE FOR SHADOW COPIES” notice?

Thank You,

Alessandro

 

I think this is the same as the System Restore bug mentioned earlier by myself and a few others. Try the Registry fix AND a restart:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71a27cdd-812a-11d0-bec7-08002be2092f}
UpperFilters        REG_MULTI_SZ     volsnap

Hello Alsssandro, 

 

what was your exact problem and how did u solve it ?

 

Hi Inet,

The last weekend after a windows update big session, two of my servers (one server 2012 r2 and a 2016 one), where it was installed kaspersky antiransomware, during the sunday reboot, had a blue screen error with loop restart (error “Critical Service Failed”). The only way to access windows was to choice, pressing f8 during boot, “disable driver signing enforcement”, after reading this post, I’ve found that may CATROOT and DRIVERSTORE directories were blank (and a  registry key deleted!!). So, following pdwk steps solved all the problems, and now the servers are working well.

Thank You for that, the .reg  fix (as recommended in the links) did not solved. But adding it manually worked. 

No more “K“ in my life.

Thank You again. Have a nice day.
