Updated July 27, 2016

Supports: NCM version 7.4

Requirements vary based on:

  • The number of nodes
  • The frequency of configuration downloads
  • The length of time that configurations are maintained in the database

For additional information on requirements and configurations, see the Multi-module system guidelines. You should also review your product administration guides and release notes for the exact product requirements beyond these minimums.



Operating System

  • Windows 2003 Server SP2 (32-bit and 64-bit) including R2 SP2, and with IIS installed and running in 32-bit mode
  • Windows 2008 Server Enterprise or Standard (32- bit or 64-bit) including R2, with IIS installed and running in 32-bit mode, and Server 2008 R2 SP1
  • Windows Server 2012 and Windows Server 2012 R2

For evaluation purposes only:

  • Windows 7 SP1
  • Windows 8 (except Standard edition)
  • Windows 8.1 including Update 1 (except Standard edition)

Installation on a Windows Domain Controller is not supported.

Operating System Language
  • English
  • German
  • Japanese
  • Simplified Chinese.

NCM does not support using locales outside the group of supported operating system languages.

SolarWinds NCM Server Hardware

CPU Speed

3 GHz dual core dual processor



Hard Drive Space


This version of SolarWinds NCM holds a searchable config index on local disk that adds 6-10GB additional disk space to the previous requirement.

Installing Windows Account

Requires administrator permission on the target server.

File System Access Permissions

Ensure the Network Service account has modify access to the system temp directory: %systemroot%\temp.

SolarWinds Orion Syslog Server

If you want real time change detection triggered through devices sending Syslog messages, the executable must have read and write access to the Orion Platform database.

SolarWinds Orion Trap Service

If you want real time change detection triggered through devices sending SNMP traps, the executable must have read and write access to the Orion Platform database.

Microsoft SNMP Trap Service

Must be installed if you want real time change detection triggered through devices sending SNMP traps.

Microsoft IIS

Version 6 or later. DNS specifications require hostnames to be composed of alphanumeric characters (A-Z, 0-9), the minus sign (-), and periods (.). Underscore characters (_) are not allowed.

SolarWinds neither recommends nor supports the installation of SolarWinds NCM on the same server or using the same database server as a Research in Motion (RIM) Blackberry server.

Microsoft ASP .NET 2.0 Ajax Extension

Version 1 or later

If this is not found on the target computer, the setup program downloads and installs the component.

Microsoft .NET Framework

Version 4.0.3 

If the required version is not found on the target computer, the setup program downloads and installs it. Ensure that .NET is turned on in Windows Features.


You must create the SolarWinds Orion database with the SolarWinds Configuration Wizard. Creating the database another way is not supported.

SolarWinds supports using NCM with database servers set up in these languages: English, German, Japanese, and Chinese, but only supports storing characters in the UTF-8 set.

The following database servers are supported:

  • SQL Server 2014 , and with Always On Availability Groups
  • SQL Server 2012, with or without SP1 and SP2, Standard or Enterprise, and with Always On Availability Groups
  • SQL 2008 R2 without SP, 2008 R2 SP1, 2008 R2 SP2
  • SQL 2008 without SP, 2008 SP1, 2008 SP2, 2008 SP3

You can use the following database select statement to check your SQL Server version, service pack or release level, and edition:

select SERVERPROPERTY ('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')

The following SQL server collations are supported:

  • English with collation setting SQL_Latin1_General_CP1_CI_AS
  • English with collation setting SQL_Latin1_General_CP1_CS_AS
  • German with collation setting German_PhoneBook_CI_AS
  • Japanese with collation setting Japanese_CI_AS
  • Simplified Chinese with collation setting Chinese_PRC_CI_AS

Your database server must support mixed-mode authentication or SQL authentication and have the following protocols enabled:

  • Shared memory
  • TCP/IP
  • Named Pipes

SQL Server 2008 Express Edition does not enable these protocols.

The following x86 components must be installed:

  • SQL Server System Common Language Runtime (CLR) Types
  • Microsoft SQL Server Native Client
  • Microsoft SQL Server Management Objects

If the components are not found on the target computer, the setup program downloads and installs the components.


The following ports may be needed for Orion Web Console, depending on how SolarWinds NCM is set up to download and upload configurations:

Note: If you are installing NCM in an integrated environment with NPM, see also the port requirements in the SolarWindsNetwork Performance Manager Administrator Guide.

  • 20: FTP data transfer
  • 21: FTP control (setup/teardown)
  • 22: SSH/SCP default for NCM to transfer configs
  • 23: TELNET default for NCM to transfer configs
  • 25: SMTP email default that NCM uses for notifications
  • 69: TFTP server listens on it
  • 80: HTTP default for Orion Web Console
  • 161: SNMP statistics collection, the default for polling in NCM
  • 162: UDP trap messages listened for and received by Trap Server
  • 514: UDP Syslog messages arrive for Orion Syslog Service
  • 17777: SolarWinds Information Service for Orion Web Console
  • 17778: SolarWinds Information Service for Orion Web Console
  • 17779: SolarWinds Information Service for Orion Web Console
  • 1801: TCP used for MSMQ WCF binding


  • Microsoft Internet Explorer 8, 9, 10, 11 (standard and mobile views)
  • Mozilla Firefox 10.0.9, 16.0.2
  • Google Chrome v22.0.1229.96, 23.0.1271.64

Additional information

  • The SolarWinds Network Configuration Manager Information Service requires the Net. Tcp Port Sharing Service to be enabled and port 17777 open for TCP traffic to the SolarWinds NCM computer. By default, this service is disabled. The setup program sets the service to manual. Resetting the service setting to disabled will adversely affect your installation.
  • To take advantage of the numerous integration points in SolarWinds Network Configuration Manager, install the SolarWinds Engineer's Toolset on the same server. You can also take advantage of integration points built into the Web Console by installing the Toolset on computers used to access the Web Console.


NCM 7.4 was tested for scalability in a standalone deployment of three servers: one server hosts the main NCM server and the other two servers each host an additional NCM polling engine. The main NCM server manages up to 10,000 NCM nodes, as does each additional NCM polling engine. Therefore, the deployment supports up to 30,000 nodes total.

The standard Orion Web Console deployment has the Orion Platform on the main NCM polling for node status at the default rate. This deployment supports two NCM operations (inventory update and configuration download) performed per day on all 30,000 nodes.

Though the main NCM server and each additional polling engine can manage up to 10,000 nodes, the actual total depends on the system hardware of the server hosts, the types of devices being monitored, and the number of jobs being run concurrently. Should you need to manage more devices, and you decide to add NCM servers, consider consolidating your views of multiple servers with the Orion Enterprise Operations Console. For more information about scaling NCM, please contact your account manager.

Server sizing 

SolarWinds Network Configuration Manager can perform configuration management for any sized network, from small corporate LANs to large enterprise and service provider networks. Most SolarWinds NCM implementations perform well on Pentium-class 3GHz systems with 4GB of RAM using the default simultaneous transfer settings, with no modifications to node monitoring settings.

Should scalability issues arise, adjust the following:

  • Number of simultaneous transfers
  • Frequency of uploads, downloads, and inventory jobs
  • Node polling interval for up/down monitoring

Inventory jobs may run longer than expected in larger environments. To remedy this situation, break large inventory jobs into smaller jobs that do not include as many nodes, and space these jobs over a longer period of time. Adjusting server CPU and memory will enhance user interface performance and job execution speed.
