grant private key access for account NT Authority\Network Service

I have a digital certificate from a third party and when I try to run the following ms-dos command to grant access to the NETWORKSERVICE account I am getting the following error.

winhttpcertcfg -g-c LOCAL_MACHINE\MY -s "TransUnion Net Access Client" -a "Networkservice"

Error: Unable to update security info for key container error = 0x5.

What does that mean? How can I allow my certificate access to the NT Authority\Network Service account?

Thanks in advance for your help!

Just for reference I include the following. I ran this command 

winhttpcertcfg -l-c LOCAL_MACHINE\MY -s "TransUnion Net Access Client"

Currently only the following accounts have access to the private key:

  • BUILT IN\Administrators
  • NT AUTHORITY\System
Solution

  • I found the solution to my problem. I need to run as administrator the DOS command prompt and that should do it.
