After doing some changing and setting. The problem is getting worse, but at least now i know why my office communicator 2003 is not working last time.
The recent changes that I am that cause the OCs not working is unjoin and rejoin the domain workgroup. After I did that, my OCS 2003 is unable to connect and reply with the following error " There is problem verify the certificate from the server, Please contact your administrator".
To confirm that my network is working, using the same notebook Windows 7. I start my VMware (Win XP) and try to connect to OCS 2003, dissappointing me, my VMware XP are able to connect to OCS 2003.
What the hell is problem with my Windows 7......:'(
This is the 4th time i format my notebook....
