Additionally, the following event is logged in the System log on the protected servers:
- Another process is using TCP port 5718 and TCP port 5719. These two ports are required by the DPM protection agent service.
- TCP port 5718 and TCP port 5719 are not open for firewall applications or for firewall devices on the computer.
Resolution 1To resolve this problem, find the process that is using the required TCP ports. To do this, follow these steps:
- Open a Command Prompt window. Run the following commands at the command prompt:netstat -ano > netstat.txtNote In this step, the command outputs of the netstat command and the tasklist command are written to text files so that you can check the outputs more easily. Run the tasklist command together with the /svc switch because the process that is using the required ports may be running as a service.
tasklist > tasklist.txt
tasklist /svc >svclist.txt
- Open the text files that were generated in step 1. To do this, run the following commands at the command prompt:notepad netstat.txt
- In the Netstat.txt file, find any entries that correspond to TCP port 5718 and to TCP port 5719. Note the process identifier (PID) for each entry.
- In the Tasklist.txt file, locate the PIDs that you found in step 3 to determine which processes are using the required ports. If you do not find the PIDs in the Tasklist.txt file, try to find the PIDs in the Svclist.txt file.
- After you find out which process is using the required ports, configure the corresponding program to use other available ports. If you cannot change the program's ports, or if the program uses ports dynamically, you must stop the program.
To change the ports that are used by the DPM agent, follow these steps on the protected computer that is experiencing the problem. Make sure that the ports that you reassign will not used by any other applications.
- Locate the SetAgentcfg.exe file from the DPM server. By default, the file is located at the following path: %PROGRAMFILES%\Microsoft DPM\DPM\Setup\SetAgentCfg.exe
- Copy the file to the protected computer that is experiencing the problem. Copy the file to the agent DPM\Bin directory. By default, the file is located at the following path: %PROGRAMFILES%\Microsoft Data Protection Manager\DPM\bin
- On the protected computer that is experiencing the problem, open an administrative Command Prompt window.
- In the Command Prompt window, change to the directory to which the SetAgentCfg.exe file was copied. For example, change to the following directory:%PROGRAMFILES%\Microsoft Data Protection Manager\DPM\bin
- Run the following command to change the ports that are used by the DPM Agent:SetAgentCfg e dpmra <port number> <alternate port number>
- Restart the DPMRA service.
Resolution 2To reserve TCP ports 5718 and 5719, follow the steps that are documented in the following Microsoft Knowledge Base (KB) article:
Data Protection Manager 2007 also uses the following ports:
- TCP 135 dynamic
- User Datagram Protocol (UDP) 53
- UDP 88
- TCP 88
- UDP 137
- UDP 138
- TCP 139
- TCP 389
- UDP 389
