I am in the middle of installing SBS 2003 R2 Premium on a client's new server. I've already blogged some of my 'experiences'. Today I ran into another 'interesting' issue. I installed ISA server but when I did the Configure E-mail and Internet Connection Wizard (CEICW) it errored. I tried accessing the server via RDP and could not. Then I had a look at the Services and found none of the ISA or Firewall services were running. Nor could I start them. I looked in the Event Applications log and found Event ID 14109, "The ISA Server Standard Edition cannot run. Either the server is using more than 4 processors, or it is configured to use the Active Directory services....". Well, this server only has TWO processors, the legal limit for SBS. However, each processor has FOUR cores. So the server is seeing EIGHT processors, double what ISA will allow. Old software meeting new hardware! How do you solve old software problems? With a service pack, of course. Googling the error message produced a recommendation to install the latest service pack for ISA. So I downloaded SP3 for ISA Server 2004 and installed. Now ISA is happy. CEICW is happy. And, I can not remote into the server so I can finish configuring it from the comfort of my den.
