Hello, I'm creating a batch which adds network drives. for a user when it logs on. I got the script this far that it will check if the drive already exists and if it does it will be deleted and created again. But how do I check if the network source is available? If the server is offline the network drive can't be created.. this is the script I have so far @echo off if not exist X:\nul goto NOT_EXIST MD X:\mytemp if not exist X:\mytemp\nul goto NOT_READY Rmdir X:\mytemp net use X: /delete goto create_X :NOT_EXIST net use X: \\[servername]\data\users\post echo Drive X:\ is aangemaakt. goto next :NOT_READY echo Drive X:\ is nog niet klaar! goto fout :create_X net use X: \\[servername]\data\users\post echo Drive X:\ is aangemaakt. goto next :fout pause echo Er is een fout opgetreden bij het aanmaken van drive X:\, neem AUB contact op met uw systeem beheerder goto end :next if not exist W:\nul goto W_NOT_EXIST MD W:\mytemp if not exist W:\mytemp\nul goto W_NOT_READY rmdir W:\mytemp net use w: /delete goto create_w :W_NOT_EXIST net use w: \\[servername]\data\users\archief echo Drive W:\ is aangemaakt. goto end :W_NOT_READY echo Drive W:\ is nog niet klaar! goto fout :create_w net use w: \\[servername]\data\users\archief echo Drive w:\ is aangemaakt. goto end :end As you can see there are 2 network drives created X and W, if they already exist they will be deleted and again created. but if the network source is unavailable the creation will result in an error. Is it possible to do a check on a network source? like this if not exist \\[servername]\data\users\post goto fout I hope someone can help me with this. Greetz Michel

In the meanwhile I had the time to test some things out. and it seems that it works to check a network path with if no exist \\[servername]\data\users goto fout I also perfected the script a lill more. if someone has tips it would be great!! @echo off if not exist X:\nul goto create_X MD X:\mytemp if not exist X:\mytemp\nul goto NOT_READY Rmdir X:\mytemp net use X: /delete goto create_X :NOT_READY echo Drive X:\ is nog niet klaar! goto fout_X :create_X if not exist \\[servername]\data\users\post goto fout_X net use X: \\[servername]\data\users\post echo Drive X:\ is aangemaakt. goto next :fout_X echo Er is een fout opgetreden bij het aanmaken van drive X:\ neem AUB contact op met uw systeem beheerder pause goto next :next if not exist W:\nul goto create_w MD W:\mytemp if not exist W:\mytemp\nul goto W_NOT_READY rmdir W:\mytemp net use w: /delete goto create_w :W_NOT_READY echo Drive W:\ is nog niet klaar! goto fout_w :create_w if not exist \\[servername]\data\users\archief goto fout_W net use w: \\[servername]\data\users\archief echo Drive w:\ is aangemaakt. goto end :fout_w echo Er is een fout opgetreden bij het aanmaken van drive W:\ neem AUB contact op met uw systeem beheerder pause goto end :end

Yes, you are correct in you observation. As long as the user is logged-on and permissions allow the user access to the server resource, it IS valid to use UNC file names in a batch file.

The users that the batch file aplies to do have access to these network resources. (They have the neccesairy permissions so no user authentication is required.) If my observations are correct this line if not exist \\[servername]\data\users goto fout will check if they can establish a connection to the server. If this check failes you'll get an error which stays in the screen with the Pause command. If all goes smoothly the user will barely notice the script. Still haven't got the change to test out the script in the actual business envoirment. But I've created a 2nd (simpler one) to test in my own envoirment. It seems to work just fine. The thing is that I don't know how the script will react on other warnings...
