Hay, I want to use the "Rapid Release Definitions (via FTP)" option that comes with SMS 4.6. The ISA 2000 is opened for Symantec's live update & for FTP but it still doesn't work. If I activate the firewall client on the server it works fine. Here are the logs With FW client: 205.252.48.160 Tcp 21 26146 ALLOWED Without FW client 205.252.48.160 UDP 1025 137 BLOCKED Anyone know how this can be accomplished? Cheers Avi
