I realize this question has been asked and answered before but there have been conflicting answers. I rather ignorant of how to properly configure ISA and do not want to accidently lock my system down by performing the upgrade.
1. The main conflict I have seen in the answers is use the SBS 2003 SP1 Premium CD to perform an upgrade or to uninstall ISA 2000 and do a clean install of ISA 2004. A consultant set up my box so I am trying to decifer what rules were created to make ISA 2000 work for my company. Any suggestions on which method I should use?
2. I saw a posting somewhere that I should export my certificate, install ISA 2004 then import the certificate. I've seen this mentioned in a couple of places but would like to know your advice.
3. Are there any good ISA 2000 and ISA 2004 introductions that can aid me in understanding how things work, how to configure ISA and the implications of running CIEW? I ran into an issue last week where all of a sudden my client PC's could not log into https sites. I ran CIEW and it solved that issue but created others, such as having to reconfigure the connection properties in all browsers to use the proxy server at port 8080 to browse, and my Blackberry Enterprise server stopped working (running CIEW appears to automatically reset authentication required, I had to pay the consultant to figure that out).
4. Does anyone know of really good step by step instructions for performing the ISA 2000 to ISA 2004 upgrade that takes into consideration the current configuration rules, current certificate, and provides good details on how to handle any client issues including how to handle users who are using laptops on the road when the upgrade exists?
Thanks,
Bob
