The DNS hostname is too long

Overview

 

Error: The DNS hostname is longer than 15 characters.

 

Environment

  • NPM
  • SAM
  • NCM
  • NTA
  • SRM
  • EOC
  • IPAM
  • UDT
  • VNQM

 

Cause 

 

The hostname is longer than 15 characters. Microsoft trims any characters beyond the fifteenth in a NetBIOS-resolved hostname. A trimmed hostname may prevent Orion services from properly identifying your SolarWinds Orion Main Poller. We recommend using a DNS hostname that is less than 15 characters long

Resolution

  1. Change the hostname on your Orion Server to be less than 15 characters:
     

Windows Server 2008 R2:

Click Start, right-click Computer, and then click Properties. This will open the System dialog.

In Computer name, domain, and workgroup settings, click Change settings to get to the System Properties dialog. 

Click Change to get to the Computer Name/Domain change dialog.

In Computer Name, type the name for your computer. 

Click OK twice

Click Close

You will be prompted for a restart for the changes to take effect.

 

Windows Server 2012:

Click on Server Manager

Click on Local Server

Click on the current Computer Name to open the System Properties dialog box.

Click Change to get to the Computer Name/Domain change dialog.

In Computer Name, type the name for your computer. 

Click OK 

Click Close

You will be prompted for a restart for the changes to take effect.
