Details

DCOM

135/TCP   Dynamic

The DPM control protocol uses DCOM. DPM issues commands to the file agent by invoking DCOM calls on the agent. The file agent responds by invoking DCOM calls on the DPM server.

TCP port 135 is the DCE endpoint resolution point used by DCOM.

By default, DCOM assigns ports dynamically from the TCP port range of 1024 through 65535. You can, however, configure this range by using Component Services. For more information, see Using Distributed COM with Firewalls (http://go.microsoft.com/fwlink/?LinkId=46088).

TCP

3148/TCP

 

3149/TCP

The DPM data channel is based on TCP. Both DPM and the file server initiate connections to enable DPM operations such as synchronization and recovery.

DPM communicates with the DPM Agent Coordinator on port 3148 and with the file agent on port 3149.

DNS

53/UDP

Used between DPM and the domain controller, and between the file server and the domain controller, for host name resolution.

Kerberos

88/UDP

88/TCP

 Used between DPM and the domain controller, and between the file server and the domain controller, for authentication of the connection endpoint

LDAP

Used between DPM and the domain controller for Active Directory queries.

NetBIOS

137/UD
