Computers loose network connection when SQL Navigator is running.
This happens mostly over night.
The computer is not reachable via network so it is necessary to reconnect the PC to thenetwork.
Asthere are developers connecting to their computers remotely, they are not able to work and they have no chance to reach the pc any more.
This seems to be a problemwith the Intel 82567ML-3 Gigabit Network Connection.
The problem also happens when SQL Navigator is not running.
Please upgrade to the latest driver ofyour network.
This might fix the problem.
