When you install the System Center Virtual Machine Manager (VMM) server, you can assign some of the ports that it will use for communications and file transfers between the VMM components. While it is a best security practice to change the default ports, not all of the ports can be changed through VMM. The default settings for the ports are listed in the following table.
| Connection type | Protocol | Default port | Where to change the port setting |
|---|---|---|---|
| VMM server to VMM agent on Windows Server–based host (control) | WS-Management | 80 | During VMM setup, registry |
| VMM server to VMM agent on Windows Server–based host (file transfers) | HTTPS (using BITS) | 443 (Maximum value: 32768) | Registry |
| VMM server to remote Microsoft SQL Server database | TDS | 1433 | Registry |
| VMM server to P2V source agent | DCOM | 135 | Registry |
| VMM Administrator Console to VMM server | WCF | 8100 | During VMM setup, registry |
| VMM Self-Service Portal Web server to VMM server | WCF | 8100 | During VMM setup |
| VMM Self-Service Portal to VMM self-service Web server | HTTPS | 443 | During VMM setup |
| VMM library server to hosts | BITS | 443 (Maximum value: 32768) | During VMM setup, registry |
| VMM host-to-host file transfer | BITS | 443 (Maximum value: 32768) | Registry |
| VMRC connection to Virtual Server host | VMRC | 5900 | VMM Administrator Console, registry |
| VMConnect (RDP) to Hyper-V hosts | RDP | 2179 | VMM Administrator Console, registry |
| Remote Desktop to virtual machines | RDP | 3389 | Registry |
| VMware Web Services communication | HTTPS | 443 | VMM Administrator Console, registry |
| SFTP file transfer from VMWare ESX Server 3.0 and VMware ESX Server 3.5 hosts | SFTP | 22 | Registry |
