I'm using a WINDOWS 2008R2 STD as a VPN (PPTP remote access server) server.
The clients are connect to the shared folder (SMB1.0) in internal network via WIN 2008 server with PPTP.
Today morning, I found that every clients are can not access to the shared folder on the internal network.
The clients were assigned internal IP correctly. And, the shared folders were could access at Windows 2008 server.
Ping from internal server to the client was available. But, could not access to the shared folder on the internal network.
I found KB4524157 had installed during the weekend. After remove the KB4524157, The access became normal. So, I removed KB4524157 temporally now.
May I have advice about this? The clients are using Windows7, Windows10.
