Do you have any software firewalls installed on the computer? If so, make sure you give the laptop the rights to be in the same workgroup/network.
You may want to start from the desktop and make sure file and printer sharing is enabled. You can do this by reestablishing your workgroup again through the "set up a home or small office network" link in the My Network Places window. Go through the wizard completely and do the same on the laptop.
You may also try to locate the printer by searching for your desktop on your network.
From your laptop, Click search on the start menu.
In search window, click computers or people.
Click a computer on the network.
Type the name of your desktop.
Your desktop computer name can be found by right-clicking your My Computer icon then properties.
Click on Computer Name tab. Make sure your workgroup name is the same on both computers.
It may be helpful to start your network from scratch so you might see the network from a different perspective.
I have a desktop and laptop connected on a wireless network. The desktop is running XP Pro and the laptop XP Home.
I am the system administrator on both machines with family members having (limited) user accounts.
A printer is connected to the desktop with all users having printing access.
From the laptop I was able to use the Add Printer Wizard to connect to, and network access, the printer connected to the desktop. For some unaccountable reason, that access has now disappeared. Clicking on properties from the Administrator (laptop) acccount I get the message that I do not have access and only the security tab will be displayed. Trying the Add Printer Wizard again, I'm able to navigate as far as "Desktop" but double clicking on that doesn't bring up the printer. I get the same thing when trying to add the printer through the other limited user accounts. Neither can I connect by manually entering the desktop destination of the printer.
Previously when the printer was working from the laptop Administrator's account, and going into Printer Properties clicking "Share this Printer" the sharing symbol would not display with the printer icon. I clicked off sharing and re-booted and repeated the sharing process but to no avail.
Previously when I could get access on the laptop Administrator's account, this still wouldn't work on the other User accounts.
I suspect this may have something to do with the settings in Printer Properties under the sharing and / or security tab accessed from the Desktop, but I can't find the answer. From here I've given permissions to "Everyone" but that makes no difference.
I'm really quite lost on how to get around this problem. Can anyone suggest any solutions, please ?
