<code>
PS C:\>(get-acl .\ssh_host_dsa_key).owner
otheruser
PS C:\>icacls .\ssh_host_dsa_key
ssh_host_dsa_key   NT AUTHORITY\SYSTEM:(F)
                   BUILTIN\Administrators:(F)
                   otheruser:(R) 
Steps to fix these permissions
PS C:\>icacls .\ssh_host_dsa_key /setowner system
PS C:\>icacls .\ssh_host_dsa_key /remove otheruser
At this point, you could do the following to replicate these permissions onto other host keys
PS C:\>get-acl .\ssh_host_dsa_key | Set-Acl ssh_host*key
