User ID agent with Windows 2012 NPS Problem

[onepenc]

I've follow the instruction here: https://live.paloaltonetworks.com/t5/API-Articles/PANOS-5-0-User-ID-Installation-and-configuration-i.... My UID agent is on the same server with NPS and DHCP. Here is my UIDConfig xml file:

<useridscriptconfig>
<wireless-lan-controllers>
<wlc>1.1.1.1</wlc>
<wlc>1.1.1.2</wlc>
</wireless-lan-controllers>
<Domain>RACHAPREUK</Domain>
<LogPath>C:\Windows\System32\LogFiles\</LogPath>
<LogFormat>DHCP</LogFormat>
<AgentServer>192.168.1.31</AgentServer>
<AgentPort>5006</AgentPort>
<Debug>2</Debug>
<DHCPServer>RCP-AD1.RACHAPREUK.LOCAL</DHCPServer>
<Key>Key</Key>
<VSYS>vsys1</VSYS>
<Agent>1</Agent>
<Timeout>20</Timeout>
</useridscriptconfig>

I've got this from the Monitoring tab:

And this from UIDDebug.
