Can't change setting in homegroup

[Jeff93]

If you can't change the settings in homegroup e.g to stop document sharing, or you can't enable printer sharing then make sure your Windows Firewall is on.

I've been using a default setup of an Internet Security product with it's own filewall, but Windows woul not allow me to share a printer or change what I wanted to share.

Error message: "Printer settings could nor be saved. Opperation could not be completed (error 0x0000006d9)"
