A common problem after upgrading Dr Dispatch, installing a new firewall, or moving Dr Dispatch data is that the server we use to connect to Dr Dispatch data (we call it NexusDB) is missing, which results to a screen like the one below.



  • The most common reason this problem is caused is because of firewall configurations between both the server computer, which host Dr Dispatch data, and the client computer, which accesses it. Please make sure to configure your firewall, including Windows Firewall, to allow access to both drdisp.exe (located usually in C:\Program Files (x86)\DrDispatch 5) and nxserver.exe (located usually in C:\Program Files (x86)\DrDispatch 5\server).

  • Another problem is after updating, the NexusDB server is not started. It is recommended to restart the server after updating if this is the case.

  • If you have tried the options above, and still have the problem, contact support at support@drdispatch.com describing your problem in detail.
