first of all thank you again for your work and replies (btw, reading my messages again, i may seem a bit down, but believe me i am not. just trying to help you with some test results )
another thing which is hard to identify and report is;
if i switch to blackbox shell, i am having trouble using checkpoint ssl vpn, and sometimes outlook2013 can not connect to exchange. i just guess there is something missing about CAPI (certificates) becouse, my outlook connection troubleshooting or checkpoint diagnostics seems to have issue with certificates.
switching back to explorer instanly fixes these errors.
