DCOM
135/TCP
Dynamic
The DPM control protocol uses DCOM. DPM issues
commands to the protection agent by invoking DCOM
calls on the agent. The protection 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
to 65535. However, you can configure this range by
using Component Services. For more information, see
Using Distributed COM with Firewalls ( http://
go.microsoft.com/fwlink/?LinkId=46088 ).
Note that for DPM-Agent communication you must
open the upper ports 1024-65535. To open the ports,
perform the following steps:
• In IIS 7.0 Manager, in the Connections pane,
click the server-level node in the tree
• Double-click the FTP Firewall Support icon in
the list of features
• Enter a range of values for the Data Channel
Port Range
• After you enter the port range for your FTP
service, in the Actions pane, click Apply to
save your configuration settings
TCP
5718/TCP
5719/TCP
The DPM data channel is based on TCP. Both DPM
and the protected computer initiate connections to
enable DPM operations such as synchronization
and recovery. DPM communicates with the agent
coordinator on port 5718 and with the protection agent
on port 5719.
DNS
53/UDP
Used between DPM and the domain controller, and
between the protected computer and the domain
controller, for host name resolution.
Kerberos
88/UDP
88/TCP
Used between DPM and the domain controller, and
between the protected computer and the domain
controller, for authentication of the connection
endpoint.
LDAP
389/TCP
389/UDP
Used between DPM and the domain controller for
queries.
