Yes, you are right! Wednesday night I double-checked everything physical and joined a thin client directly on the server, just to eliminate possible errors. And, voila, two faults was found: * One cable I inserted was changed out by someone, and the new one did not work. I found the culprit (cable), and of course changed it. A bit more embarrising though: * There is an unused network plug on the server, I though I had tested wich one was the right, but, well, obviously not good enough. So thank you all for all input, now I am glad it finally works! Conclusion: Double-checking pays off :-) All the best Axel.
