One single 2003 server SBS, with AD. A couple of XP Pro computers, all of them joined to the domain.
Sharing a printer from server works fine (permission are set correctly yes) but we have one locally installed printer at a PC (LPT1) and I can share it, set permissions to everyone = full access, it shows up in the AD catalog.
But then adding a new printer from another PC (or from the server, does not matter) I get a popup box asking me for credentials. Same thing happen then sharing a folder from that PC.
There must be something "basic" with this PC I miss.
