Unable to import drivers into SCCM 2503

While trying to import the LAN drivers into SCCM version 2503, I encountered an error.

The errors are,
1. Error: Some driver(s) can not be imported successfully.
2. Error: Failed to import the following drivers:
• Realtek PCIe GbE Family Controller - An error occurred while importing the selected driver. 

Can anyone help me resolve this issue?
