Hi Raj,
I have a notebook running Vista, and my husband has a Desktop running XP. The printer is connected to his desktop via usb and both of our computers are connected to a router.
I went online with Dell Tech support, and that guy tried alot of stuff, but never could resolve the issue.
If I try to add the printer from control panel, I can select add a printer from a network, and it sees the printer and tries to connect, but then I get a message that says " Windows cannot connect to the printer. Operation could not be complete. Error 0x0000000d".
If I go to the networks, and click on his (host), I can see the printer and if I try to click on it, it attempts to connect, but then I get a message that says Windows could not connect, there is not enough memory, close programs and try again, but I dont' have anything running.
If I go through my network and try to add a printer, I get a message that says I dont' have permissions, which I dont' understand because I am the only user on the notebook.
This is so frusterating....

Any help is appreciated.
