The DPMRA service terminated with service-specific error 10048

After maintenance on one of the Exchange CAS/HUB servers the DPM server could not contact the DPM agent anymore.

The Error Code:

Log Name:      System
Source:        Service Control Manager
Date:          17-7-2009 14:36:34
Event ID:      7024
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      servername.domain.local
Description:
The DPMRA service terminated with service-specific error 10048 (0x2740).

This article on Microsoft site tells that this could be caused by another service running on the ports used by DPMRA service. (port 5718 and 5719)

To find which service this is you can use the command netstat –oan, this returns the ports and the corresponding PID. With the command tasklist /svc  you find the service involved.

In this case the service MSExchangeFDS (Microsoft Exchange File Distribution) was running on both ports.

We used the following work around:

• Stop the Microsoft Exchange File Distribution service
• Set the DPMRA service from manual to automatically
• Start the DPMRA service
• Start the Microsoft Exchange File Distribution service

This work around fixed the issue for us.
