Root Cause
When try to login to OSN8800 / 3800 via U2000 & WebLCT, connection failed with error of LCT login disable

1. The NE was locked out from U2000.
2. Customer or previous engineer had set for local access to be single login.
3. In Navigator, at login screeen, the NE ID and password input will then allow U2000 to connect.If not connect using Navigator first, there is no establishment of authentication connection between laptop and the OSN series equipment
4. Example was, there were two local NE with NE ID 55 and 56. If we login using Navigator by input NE ID 55, in U2000, only NE 55 will able to login, if NE 56 will display LCT login disabled.
