I’ve updated from 1.6.0 to 1.8.0 and right after that got errors from tailscale:
Source NETBT error 4311:
Initialization failed because the driver device could not be created. Use the string “000000000100320000000000D71000C0110100009A0000C09B040000000000000000000000000000” to identify the interface for which initialization failed. It represents the MAC address of the failed interface or the Globally Unique Interface Identifier (GUID) if NetBT was unable to map from GUID to MAC address. If neither the MAC address nor the GUID were available, the string represents a cluster device name.
And window pop up:
After digging taskmanager I’ve found that several users logged on and started tailscale-ipn.exe automatically. It happened because Tailscale installer puts tailscale.lnk to StartUp folder for all users on server - C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp .
Just remove link from this folder and leave it only for your user.
