Installing ISA 2006 in a Windows 2003 domain?

I want to do a domain install of isa2006 in my network. The diagram below shows what I want to achieve. With the exception of the isa server the diagram below is the exact format of my network at the moment.

                                                    Internet
                                                          |
                                                          |
                                             PIX external Nic
                                                          |-----------PIX Dmz Nic --------------
                                                          |                                                 |                                          
                                             PIX Internal Nic                            web server                              
                                                          |
                                                          |
                                             ISA External Nic
                                                          |
                                             ISA Internal nic
                                                          |
                          ---------------------------------------  internal LAN --------------------------------------
                                      |                                                                 |
                                 FE/BE exchange server                                                WorkStations/Servers

The ISA will be a domain install.

1. To start the install do I install win svr 2003 and join it to the domain before installing the isa server or do I install both in a workgroup and then join the domain?

Hey,

Make sure to select the correct servername and add it to the domain, after that start installing ISA... Renaming an ISA server when allready in a domain can cause some issues...

Should I be using Win svr Standard or Enterprise edition?

I would say standard because i don't believe you will need that much memory for just an ISA server (standard goes up to 4Gb, right? don't have the figurs in my head). That's, IMHO, the only reason for using an Enterprise edition.. Also, if you need more "power" from your servers, you'd better go for a second ISA server and set it up in an NLB cluster, then you have High Availability also :)
