Cant add printer

Hi,

I cant add printers from some machines, when i go to the add printer’s tab i can’t see any of the printers. I have 2 printers shared on my network and my network consists of machines that run windows 2000/xp.

Alternatively I can add those printers if i connect to the computer that has the printer attached locally but then i loose this connection once i reboot the computer or log off. I again have to add in the same way.

Can any one of you help me in this.

Thanks,

Amit.
