Let me explain my server setup. I have a server with 16 gig ram and 4 IPs. I installed VMware ESXi on it which took 1 IP address. For rest 3 IPs I created 3 VMs with Windows Server 2008 R2 Standard.
1. Active Directory Domain Services (3 GB RAM)
2. Microsoft SQL Server 2008 R2 (6 GB RAM)
3. Microsoft Exchange Server 2010 SP1 (6.5 GB RAM)
I added VM1 public IP to VM2 & VM3 primary DNS and then joined AD from VM2 & VM3. Installed SQL Server with AD Admin account. Now trying to install Exchange with HOSTING MODE switch but getting errors.
