After some recent Vista updates I could no longer access my shared printer on a peer Windows XP machine by the computers ip address.

So in this case I have a computer managing a printer with the ip address of 192.168.100.115 which has a computer name of gx280-06.

I have always been able to access the printer by the computers ip address using Windows Vista up until a few days ago. After the mid November updates I just get the error 0×0000709.

Tip: If you get the above error try accessing the shared resources by UNC path in my case \\gx280-06. Click on Computer and in address line type \\ followed by the name of the computer managing the printer.

I am not sure if this is intentional or a new bug, but UNC paths work so try that.
