The FPCLDT collection provides access to all the FPCLDTEntry objects of an ISA Server computer. Through this collection you can add, delete, and modify individual entries of the Local Domain Table (LDT).
Each entry in the table is stored as an individual FPCLDTEntry object.
An LDT lists all the servers in the internal network behind the ISA server. When a client requests an object from a computer and requires name resolution, the client checks the LDT. If the domain name does not appear in the LDT, then the client requests that ISA Server resolve the domain name on its behalf.
After the name resolution server returns the Internet protocol (IP) address of the destination server, the LAT is used to determine whether to go directly to that address or through ISA Server.
Clients use the LDT to determine if a name resolution request should be performed directly or by way of ISA Server. Firewall clients maintain a copy of the LDT, which is updated regularly, on their computer. When a Firewall client attempts to resolve a name, it checks the LDT. If the name is in the LDT, then the Firewall client resolves the name directly. Otherwise, it requests that ISA Server resolve the name by passing the request to a DNS server on the Internet.
The FPCLDT collection is a property of the FPCNetworkConfiguration object.
