This error is associated with multiple root causes which are outlined below:Note: Take into consideration that the majority -if not all - of these procedures require the user to have Admin Rights in the machine or explicit privileges to install, configure services and/or change registries. If you do not have Admin Rights, get in contact with your IT Administrator so they can either, grant you temporary Admin Rights or help you with the troubleshooting.
Removing MAX and all other NI applications from the blocked programs list is necessary for proper functionality. Some commonly blocked NI programs are: NIMax.exe, nimxs.exe, NiAsstnt.exe, nipalsm.exe, nidevmon.exe
. This simple solution should be one of the first options explored when a database connection issue is seen in MAX - prior to uninstalling NI software.
NOD32 Anti-virus software could be blocking the HTTP port that MAX uses for the database. Please see: Why Do I Get "MAX Database Connection Error" When Using NOD32 Anti-Virus Software?
- NI Configuration Manager or NI Device Loader (nidevldu) Services Not Started

. Scroll down to NI Configuration Manager (may show up as nidevldu
). You may also launch Services by navigating to Start»Run and entering services.msc
If the NI Configuration Manager service does not appear in the list or has problems starting, the first thing to try is a Repair of MAX
Make sure the service's Status is started. If it is not, right-click it and select Start
. Also, try restarting the NI Device Loader service. For these changes to take effect, close out of Administrative Tools, and restart MAX. If the NI Configuration Manager or nidevldu
service was not started before, MAX should now be able to operate correctly.
If you previously had configured a Serial or GPIB-ENET device but this device is no longer connected, the server may experience some delays due to the timeout that occurs while trying to connect to the non-existent device(s).Due to the delay, MAX may report a Database Connection error. In this case, reconnecting the ENET device to the system or removing the reference to the ENET device will resolve this error. When switching between a Macintosh to a PC, you will need to reset the device to have it accessible.
