Microsoft Teams Crashing on Startup\Sign in

Teams developed a crash on startup.
Saw various messages such as an Azure AD sign in failure whch s strange as we don't use Azure AD for local domain authenticaton.
We do use a centrally provided Azure sign in for Office 365 applicatons though.

Finally tracked down this article on the excellent Petri site:

Gave the option to delete the Teams cache at %AppData%\Microsoft\Teams and this fixed the issue straight away.

The teams client did initially come up wth my AD logon, so perhaps it was trying to authenticate my domain logon against Azure?

Retroarch does not recognise my controller

Despite have autoconfig setup for input device, the Retroarch snap on Ubuntu 18.04 would not work with my cheap PS3 like controller.

Turns out this is a disconnect between the snap and USB gamepad\joystick support:

You need to connect the controls to the snap using:

  • sudo snap connect retroarch:raw-usb
  • sudo snap connect retroarch:joystick
Thanks hunterk!

Windows 10 unable to access SYSVOL and NETLOGON on 2008 R2 Domain Controllers

I found some help here:
Looks like the SMB security needs to be weakened to allow Windows 10 to access these shares.
Enable the following policy:
  • Computer -> Administrative Templates -> Network -> Network Provider -> Hardened UNC Paths
You can either put the following in "Show Values":
  • \\*\NETLOGON    RequireMutualAuthentication=0,RequireIntegrity=0,RequirePrivacy=0
  • \\*\SYSVOL    RequireMutualAuthentication=0,RequireIntegrity=0,RequirePrivacy=0
Or put an entry for each DC:
  • \\DCNAME    RequireMutualAuthentication=0,RequireIntegrity=0,RequirePrivacy=0
