                keep you're patience or start a good topic next time with all the info

                Some articles to review:
                http://www.isaserver.org/articles/IS...OP3Access.html
                http://www.experts-exchange.com/Secu..._21715189.html

                  It is time to upgrade, but to SBS 2003! Since it is a suite, you cannot upgrade ISA2000 alone.
                  To test what ports you have open you could use "Shields Up" at www.grc.com and it will show you what is open from ports 1-1024.

                    Steve has expanded the port scan to 1056 now. More bang for the free buck.
                    1 1 was a racehorse.
                    2 2 was 1 2.

                        But what aspect of this thread are you referring to?

                          Oh, I wasn't sure if it was possible to perform an ISA upgrade only.
                          That's why i kept it basically to recommend to upgrade.

                            Going a bit OT but here it is. SBS 2003 upgrade from SBS gets you the basic (now unsupported) RTM edition with SQL2000 and ISA 2000. Update to SP1, you get to update to ISA 2004. UpGRADE to R2 you get SQL2005 WE (along with Update Services aka WSUS 2).
                            See the versions matrix in the Stickies in this forum!
