Not retrieving user data (USERID)

Hi there

I'm having some issues with several Windows computers with Windows 7 and 10.

I'm not receiving the "User" field of the inventory that is the logged user in the pc when performs the inventory task.

I have perform the inventory task with the user logged. In the OCS admin console, in the detail of the PC, I see that the XML have this tag:

<USERID/>

In other pcs, where the "User" field is correct, in the XML I have this:

<USERID>jesus</USERID>

This is the .ini content of one of the PCs with this problem (is the same that I have in another pcs that send correctly the User field) (for security i have changed the server name):

[OCS Inventory Agent]
ComProvider=ComHTTP.dll
Debug=0
Local=
NoSoftware=0
HKCU=0
NoTAG=0
IpDisc=
[HTTP]
Server=http://myserver/ocsinventory

User=
Pwd=
ProxyType=0

ProxyPort=0

ProxyUser=

Any idea of what could bve happening?

Thanks!!
