Leave Domain: “A general network error occurred’

KB ID 0001738 Problem After a recent lab on the test bench, I ended up with a 2008  x32 standard server. It took me a while to get this setup and running, so I wanted to keep it (or turn it into a VMware template should I ever need  another). But first I needed to ‘remove it’ from  the domain it was in. However, when attempting to do so this happened; Computer Name /Domain Changes The following error occurred validating...

Cisco ASA – L2TP over IPSEC VPN

KB ID 0000571 Problem Note: This is for Cisco ASA 5500, 5500-x, and Cisco Firepower devices running ASA Code. When Cisco released version 7 of the operating system for PIX/ASA they dropped support for the firewall acting as a PPTP VPN device. Note: If you want to use PPTP you can still terminate PPTP VPNs on a Windows server, if you enable PPTP and GRE Passthrough on the ASA. But if you want to use the native Windows VPN client you...
