When you try to provision K1000 Agent on Windows Vista and later OS and get NT_STATUS_ACCESS_DENIED error while  accessing ADMIN$ share in the logs as below.

And you have access to ADMIN$ share, then the issue could be because of the security restrictions put on administrative share while accessing them remotely.

To workaround this issue, you have to add a registry key as described below

http://en.wikipedia.org/wiki/Administrative_share#How_to_enable_in_Windows_Vista.2C_Windows_7.2C_and_Windows_8

To enable administrative shares you have to make a registry change. Click on Start Menu and in the search box type ‘regedit’ and press ENTER. Add this registry item:

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows\CurrentVersion\Policies\System
Name: LocalAccountTokenFilterPolicy
Data Type: REG_DWORD
Value: 1

After rebooting, the hidden share is accessible from other computers. Note that this change removes Windows' restrictions on remote User Account Control.

You may be able to use 'net stop server' and then 'net start server' from an administrative command prompt instead of rebooting.
