Windows 7: Computer not retaining printers

Hi Guys

I know this is a vista question but i thought someone will be able to help. I am having problems with a few users laptops at work. They have been recently upgraded to vista. Everytime their laptops are rebooted they lose their printers and they cannot add any printers. I have to uninstall "client for microsoft networks" then reboot and then reinstall for the network printers to show up and work again???

Can anyone help me on this, i haven't seen this problem before and have tried everything and looked everywhere for an answer



cheers

are you on a domain or a workgroup? Using AD? Group Policy? Roaming Profiles? We need some more information to determine how the users are logging in since it seems therein lies the issue.
