In real network, when operations master server fails due to hardware issues or some other problems, we need to move the operation master role to another domain controller as soon as possible. This move process is called seizing. Therefore, Seizing an operations master role means forcing an operations master role onto another domain controller. Before we seize operations master roles, we must permanently disconnect the domain controller that holds the operations master roles  from the network. Here, all Operation Master Roles are on KTM-DC01-2K8 domain controller. In this scenario, currently this server is Offline due to hardware problems . So we get an error when we open Operations Masters roles on other domain controller KTM-DC02-2K8 . To solve this problem, we have to seize Operations Masters roles and reassign it to KTM-DC02-2K8 domain controller as soon as possible. Before KTM-DC01-2K8 become Offline, all Operations Masters Roles are in the KTM-DC01-2K8...

Normally, organization use hardware firewall (Checkpoint, Cisco ASA, and Juniper) to secure their network (This has been the trend over last ten years). Due to some limitations of networking features in previous versions of Microsoft Firewall (ISA Server 2004/2006), large organizations used hardware firewall at the edge of network. Forefront TMG 2010 Server can fit many roles within organizations, such as Edge firewall, VPN Server, Secure Web Gateway, forward proxy, reverse-proxy and many more. Therefore, in many deployment scenarios, Forefront TMG 2010 is used solely for forward and reverse proxy functionality. In these configurations, Forefront TMG 2010 Server is typically deployed in the perimeter (DMZ) network of an existing firewall (Cisco ASA) for extra layer of protection to the web related services such as Web Server, Secure Web Server, Exchange Outlook Web access from external intrusion and attack. In this scenario we install Forefront TMG 2010 Server on ...
