RDP failed, and got system event ID 36870 fatal error occurred when attempting to access the SSL server credential private key.

It’s a wired issue.
Port 3389 is open, and can telnet to it. But if try to RDP to the server, the RDP connection will failed immediately.
And in system event log, there is an error message said “Description: A fatal error occurred when attempting to access the SSL server credential private key.”

After investigation, found out this issue was caused by the incorrect file permission were set on files within C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys.

So the fix is, grant system full control access to folder C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys as well as all files within this folder.

Increasing disk/zpool size of FreeBSDZFS disks in Linode

Leave a reply

I’m running a FreeBSD instance in Linode. And FreeBSD is not the official supported OS in Linode.The disk type is set to raw to install FreeBSD.

And recently Linode upgraded my instance and the disk size is increased from 40G to 80G.

But when I login to the system, I found that my zpool is still 40G. But the disk is shown as 80G.

# gpart show
=>       34  100663229  ada0  GPT  (80G) [CORRUPT]
         34          6        - free -  (3.0K)
         40       1024     1  freebsd-boot  (512K)
       1064        984        - free -  (492K)
       2048    4194304     2  freebsd-swap  (2.0G)
    4196352   96464896     3  freebsd-zfs  (46G)
  100661248       2015        - free -  (1.0M)

I tried to enable zfs autoexpand on my zpool, the same. Then how to increase the disk/zpool size?

First, re-write disk metadata

# gpart recover ada0
ada0 recovered

After this, gpart can show the real disk space info

#:~ # gpart show
=>       40  167772080  ada0  GPT  (80G)
         40       1024     1  freebsd-boot  (512K)
       1064        984        - free -  (492K)
       2048    4194304     2  freebsd-swap  (2.0G)
    4196352   96464896     3  freebsd-zfs  (46G)
  100661248   67110872        - free -  (32G)

Then, expand zfs partition

# gpart resize -i 3 ada0
ada0p3 resized

Then, expand the zpool

zpool online -e zroot /dev/ada0p3

Done!

#:~ # df -h /
Filesystem            Size    Used   Avail Capacity  Mounted on
zroot/ROOT/default     74G     29G     45G    39%    /

Don’t forget to write zfs info to disk

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

Open registry:

Press Control + F to launch the find window. Search for “Creative Cloud Files”, uncheck the Keys and Values boxes and click Find Next. The first result should be within a directory that begins with HKEY_CLASSES_ROOT\CLSID. Below is a screenshot of what it looks like. If you do not see this screen, keep pushing the F3 key until you find it.

Once you’ve located the directory, look for a DWORD value on the right named System.IsPinnedToNameSpaceTree.
