Solution

It is a known issue for lservnt.exe to crash when it interacts with a very long network adapter name. The lservnt.exe's buffer length is limited to 64 characters.

Here are the steps to resolve the issue:

  1. Go to Settings > Network & Internet
  2. Click Change adapter options
  3. Note the long name for the network adapter

  5. Click Rename
  6. Enter a name up to 64 characters (e.g. Ethernet0)
  7. Reboot the machine
