Problems when you want to register Microsoft CRM
A lot of customers are using ISA server 2004 these days. I have noticed that when customers that are behind a ISA 2004 server want to register Microsoft CRM it will fail.
The problem has something to do with the ISA server 2004. The ISA server was not allowing in any cases the registration wizard to complete the registration.To solve the problem I installed the Firewall Client Management for ISA Server 2004 on the CRM server and made sure the proxy was enabled inside Internet Explorer, when I did that I was allowed to complete registration without any further problems.
I will post some other possible solutions if you don't use ISA Server 2004 in the near future.
