Hi, DCOM settings can be reset to default by Security Controller (Windows start > search for this word) Reset the DCOM settings while WinCC is closed and try it again (No restart after executed Security Controller) An other point is V7.0 SP3 Update 8 which is very recommendable. I like that update because it is a good improvement. https://support.industry.siemens.com/cs/de/de/view/109741127 General OPC DCOM settings are [win]+R > dcomcnfg > and move towards to dcom config > OPCEnum should be adjusted that everyone got full permission on that process. When you open the navigation on the left side you can see my computer (right button properties) you can find "default properties" and DCOM should be selected and enabled. The attached screenshots show you all necessary OPC (WinCC) settings and all these marked options should be adjusted that all users have full permission on that. Sometimes it helps to adjust the hosts and lmhosts name resolution of Windows : https://support.industry.siemens.com/cs/de/de/view/868014 I always check and adjust these settings when I create a new connection on a new computer.
