Hello,
how to avoid automatically getting error message on starting up that network address is not valid (yah, of course is not valid if PC is down!).
All the time I should press OK.

Hello

What's the real message ?
(Something like : the network adress you use are already in use)
Then Left click on the My Network Places on the desktop, choose Properties from the menu. In the Network and Dial-up Connections, Left click on Local Area Connection, choose Properties again. In the properties window, choose TCP/IP, click on the properties button.
In the Properties Window, change the IP address section

I hope that will help you.

Hello,
sorry but is not about it.
I mean that PC is everyting OK. But for example you have remote printer on remote PC and you usualy connecting to the remote PC to start using printer or it can be network shares (when connecting to remote PC share, if was left "reconect at logon"). It is everything OK when remote PC is on, but what about when he is Off? Then at start up it is traying to find remote PC to connect to printer or to share and after some time it says something like that PC is not found (is not turn on yet - of course it's impossible to find when PC is Off!).
I want to avoid this stupid question "Do you want to recconect next time?" -YES!! I WANT TO RECONECT!. SO if is not found remote PC then leave it connection and continue loading windows, but not wait until I will press this stupid message with "Could not find PC ...bla bla ... Do you want to reconnect next time" - Of course I want!!!
