Adding this in case any C#/ASP.NET developers get this (which is my scenario, and I found this post).

I am using .NET Core in a corporate environment, and I need to check UserGroups as part of security. The code is like (where "user" is a ClaimsPrincipal):

var windowsIdentity = user.Identity as WindowsIdentity;
if( windowsIdentity is null )
    throw new Exception( $"Invalid Windows Identity {user.Identity.Name}" );
return windowsIdentity.Groups
    .Select( g => g.Translate( typeof( NTAccount ) ).Value );

Anyway, someone in charge of groups deleted a group I was part of, and the AD replication lag caused me to get the error in the title. A logoff and/or reboot worked just fine.
