I’m also having this issue, I have had it in on virtual machines and normal workstations. Restarting them seems the only way to resolve the issue. I have tried disabling the virtual adapter then reenabling and also tried restarting the service to no avail. I had to actually setup a restart task schedule on the VM’s, generally on my workstations they shutdown at night and restart in the morning so not an issue, its when they are left on it becomes and issue. Sorry not really a fix, but hopefully someone else might see this and contribute to help solve this issue.
