Incorrect logon event on Active Directory

Hi,

Intermittently ( 5 out of 10 times) I am seeing an issue.

1. I am logged onto my windows PC (10.10.10.10) with username "test1"

2. From this machine I RDP to another server (192.168.1.10) with a username 'test2'.

However after this I see a logon event in AD stating user 'test2' logged in PC 10.10.10.10 , which is my local PC.Rather AD should be showing user 'test2' logged on to 192.168.1.10.

Please help to identify where the issue could be, is it my PC settings or some issue on AD ?
