Port requirements

The following tables list the port requirements for the SolarWinds Patch Manager server and the Application Server.

SolarWinds does not recommend the use of HTTP (Port 80). Please use HTTPS (Port 443) to ensure that any web-related connections are secure.

Patch Manager server

Port Protocol Service/Process Direction Description
135 TCP RPC Endpoint Mapper Outbound Establishes WMI connections to remote computers. The server also uses this port to connect to the Service Control Manager (SCM) when it provisions the WMI providers dynamically on the remote computer.
389 TCP LDAP Outbound Provides the Active Directory authentications.
445 TCP SMB over TCP Outbound Provisions the WMI providers to a remote computer.
4092 TCP Console to Server Communication Bidirectional

Provides communications between:

  • Patch Manager servers
  • Patch Manager servers and the agents installed on client machines

Patch Manager client machines

Port Protocol Service/Process Direction Description
135 TCP RPC Endpoint Mapper Inbound Provides an SCM connection from the Patch Manager server.
445 TCP SMB over TCP Inbound Receives the WMI providers from the Patch Manager server.

Patch Manager clients with agents installed

Port Protocol Service/Process Direction Description
4092 TCP Console to Server Communications Bidirectional Provides a connection from the Patch Manager to the agent.

WSUS servers

Port Protocol Service/Process Direction Description
135 TCP RPC Endpoint
Inbound Retrieves additional data about WSUS.



TCP WSUS web service Inbound

Connects to the Microsoft Internet Information Service (IIS).

The port assignment varies based on your IIS configuration. Ports 443 and 8531 are secure ports.

WMI requirements

The following table lists the WMI requirements required by systems running Windows operating systems to establish a successful WMI connection with a remote system.

Requirement Systems

Distributed Component Object Model (DCOM)

File and Print Sharing

RPC Service

WMI Firewall Exception

Remote systems
Credentials with Local Administrator rights Remote systems in the credential ring
DCOM Local systems

WMI technology is based on DCOM / Remote Procedure Call (DCOM/RPC) communication. DCOM/RPC allocates the ports used by the server within a dynamic port range—typically between ports 1024 and 65536. To configure these ports using Windows Firewall on your managed computers, enable the Inbound Rules in the WMI group. See the Microsoft operating system documentation for details.

Ports 135, 445, and dynamic ports 1024 to 65536 must be open between Patch Manager and the remote system. See Port requirements for all SolarWinds products to review all Patch Manager ports.
