Step 1: Use the primary system’s IP Address to open your company file

  • Click Sage 50 on your system screen
  • Next, login and then pick “Open an existing company”
  • Now, locate the File name and then type the location of the IP Address where you saved your data
  • After that go to your Data File (one with the extension .SAI)
  • Finally, try to attempt to launch the company file.

Step 2:  when you got two routers

  • The very first, unplug the cable of your internal router
  • After that, you need to turn off your internal router at least for one minute
  • Now, restart your router (means plug your cable back)
  • Move to your data and then try to access your data again that means:
    • The IP address ranges of both internal router and internal service provider are conflicting.
    • The internal service provider’s router blocks the packets from its own firewall.

Step 3: The data is placed on top of a virtual machine server

  • Make sure that you have installed the Link Manager on the same server where the data is stored.
  • You are expected to install Sage Connection Manager on the same virtual server if you know that the data is on the server of a virtual machine, but not on the actual server.

Step 4: If the company file resides on a standalone system

  • Make sure your Sage Connection Manager must be in a working connection
  • Make sure you are in a position to open a sample company
  • Copy the files from your desktop and paste them
  • Try opening the file for the company from the new location.

Step 5: Reboot your Server

  • If the machines have been switched off due to an unintended mistake, the company file can still be accessed by any of the workstations
