Question:

How do I correct the error "Network Performance Monitor Startup Error: Cannot open the SolarWinds WebEngine database" when I try to view my website?

Resolution:

This error has two different causes. Your Orion configuration settings may be corrupt or incorrect, and you can resolve this by running the Configuration Wizard. Or, the Windows account that Orion uses for its web objects might not have the necessary access permissions, and you can resolve this by making this account a member of the Power Users local group.

Fixing Corrupt or Incorrect Configuration Settings

Run the Configuration Wizard to fix any configuration errors.

To fix any configuration errors:

  1. Click Start > All Programs > SolarWinds Orion > Configuration Wizard.
  2. Select the Database, Website, and Services checkboxes, and then click Next.
  3. Verify all the settings that the Wizard presents you, and fix any that are incorrect.

Adding the Web Objects Windows Account to the Power Users Group

The Orion WebEngine database uses a Windows account to access MDAC resources. Sometimes, this Windows account may not have sufficient access rights, so you must add the account to the Power Users local group.
