I have a network of around 50 computers. The outlook stops working quite often. I click on repair LAN connection and it starts working. Is there anything I can do about this other than clicking manually on repair network? 1 person needs an answerI do too

This normally happens if the connection is dropped. If the connection is dropped and the PC is unable to communicate with the DHCP then the IP address is changed and when you select repair, if it 'sees' the DHCP the problem is solved. There could be an intermittent problem with a switch or a bad connection on one or more of the ethernet cables. It could also be a problem with one of the Network Adaptors which could also be causing the problem you describe. It will be a trial an error to find what is causing the connection to be dropped. You need some patience and a plan of action such as checking the switch or switches, then the fly leads, after that if the problem persists then start checking the adaptors. Good luck
