KB00049 - Why can't people send stickies to me?

Answer 1

Have you turned on networking? Has networking been turned off (which Stickies will do for you if it's ever unable to initialise networking)? Right-click the task-tray icon, choose Settings, and on the Network tab, toggle on Enable networking.

Answer 2

Do you have a firewall running on your machine? The Windows firewall is turned on by default, and this will block Stickies from communicating over a network. Briefly disable the firewall to check whether this is causing you a problem, and if so then create a rule to permit Stickies to use the network.
