hello, i am trying to configure isa server on a dell poweredge 1600sc server, which is running small business server 2000. i followed some of the instructions from the "configuring isa server 2000" book, but now i am trying to set up my existing msn internet access on that server.i must have done something amiss or not done something in the configuration process, for i cannot access web pages of any kind including the kind that sets up my account on that computer. i can connect and was able to ping a couple of websites, but i still cannot get webpages to open, including msn's homepage or setup page. please let me know where i went wrong during isa server configuration. thank you, leon a childs jr
