First post is always frightening, but i'll live.
I've currently got a site with two locations geographically spread by around 200m.
They are currently tied together with Cisco 1200 series waps in bridge mode with directional antennas at 54mbps.
Site A - is the main site with fibre to the curb providing internet and wan activity. It currently houses a 2k8 PDC (DHCP/DNS/AD) and 2k3 BDC(DNS/Print/WSUS/Deployment/AV) and a Web server. Site A houses around 200 workstations and 50+ mobile devices, 1000 odd users.
No issues, just working really smoothly.
Site B - currently has about 50 workstations and 10 mobile devices. Workstations cabled, mobile wi-fi. All cisco Hardware. The building is going to be demolished in a years time and a new one built in its place so I'm holding out on the fibre or microwave link to get them connected flawlessly.
Im concerned that in an AD environment where there is a whole lot of traffic with the SOE currently in commission that Symantec updates/wsus updates/ logins, gpo's, software all sorts of things arent going to cope. So im trying to figure out what I do as far as getting network continuity.
Im just throwing around ideas at the moment. I'm not quite sure how to tackle it.
My thoughts are to build another DC making it a global catalog and dns server in the same Domain and localise some of the services to that server, break down the traffic flow locally.
Do clients make authoritive connections to the DC with the lowest latency or do they always pass via the PDC. Is putting another DC down at the other site a viable option? Am I going to increase replication traffic due to creating another Global Catalog? Can you throttle full replication to the back of the clock? Do I create another domain within the forest on another subnet? Am I wasting my time even considering this. Feel free to chime in. Theres too many Ideas floating around my head.
