Printer Sharename still exists after del

Hi,
i have some trouble with an W2K3 Printerserver. When i delete a printer without stopping the share and i clean the registry with all entries belong to this printer, the printershare is always visible over “net share” command. So you cannot recreate the printer with the same sharename. Stopping the Printspooler- and TCP/IP Printerserver Services does not work. Only rebooting the Server helps.
Thanks in advance
