Hello to all,
I`ve been trying to establish connection between WinCCFlex on one PC and OPC server on my laptop trought local network. Comunication from my laptop to the other PC goes both ways, with OPC Scout and WinCCFlex, but in other direction communication goes with OPC Scout but with WinCCFlex it is imposible. When I am browsing the network in the Flex it finds my laptop but it stays "blue" not green with all connections avalble. In the Administrative Tools, Event Viewer WinCCLog I find following message:

I tried with DCOM settings, firewall, etc but I can not get it throught. If it was the same for OPC Scout I would understand but like this no...
It is WinCCFlex2005 SP1 HF7
Does anyone has any ideas?
Regards
