Hi, I've got a hosting network which is completely based on windows 2000. Currently we make use of ISA server to publishing web services to the internet. Our "back" network which hosts our SQL servers is currently configured to run through a middle tier open firewall (This firewall has not been configured yet) through to the front web services. My question is this, we run one active directory domain across the whole network, with AD servers on the front and back nets. Should I split the network into two sites and configure static ports for replication or should I use Thomas's tutorial to configure replication between the AD boxes? (Problem would be the time it takes for AD to replicate between sites - min 15min :( ) Has anyone configured their network like this? Any suggestions. Thanks Steven
