Many users in Windows Vista could not reconnect to network drives on startup. Windows simply gave an error message “could not reconnect to all network drives” and users needed to enter the username and password again in order to connect with mapped network drives.
The only way to fix it is to create a batch file with the following:
net use mountdriveletter: \\server\share /user:username password
and place it inside the Startup folder.
For those who don’t know how to create a batch file, a developer has made a nifty little tool called Simple Network Drive Connector. Users just need to enter the drive letter, location of drive or folder on the network, username, and password, before hitting “Create the autoconnect file” button. It will automatically create a batch file for you.
So far, Windows 7 is not giving any trouble but everyone should know the method to fix this problem in case the error erupts again. It is a portable tool that weights around 53kb in size.
