I can't see why this is > happening. I know 1900 is the msn port ..... Any ideas ? 1900 is Universal Plug-and-Play. It's used by messanger, however messanger works just fine without it. There's registry entry to disable it: Hive: HKEY_LOCAL_MACHINE Key: Software\Microsoft\DirectPlayNATHelp\DPNHUPnP Name: UPnPMode Type: REG_DWORD Value: 2 disabled With UPnPMode=2, Universal Plug and Play Network Address Translation (NAT) traversal discovery does not occur. Apperently this is good idea to do. It seems there's more holes in UPnP than in Swiss cheese. -- Aleksandar Milivojevic Pollard Banknote Limited Systems Administrator 1499 Buffalo Place Tel: (204) 474-2323 ext 276 Winnipeg, MB R3T 1L7
