| 1406998 | 2015-08-22 07:40:00 | Sorry ran out of time whilst editing.... my post in full... You may be confusing the concepts of subnet and sub-domain subnet - simply put a "sudivided network" within an IP range. So for example... let's say your network is 192.168.1.0/24 - this is "standard" class C address range and only has 1 available subnet which allows 254 hosts. so IP range - 192.168.1.1 - 192.168.1.254 network mask 255.255.255.0 192.168.1.0 = indicates the network subnet i.e. the start of a network 192.168.1.255 = is the broadcast address of the network If we take 192.168.1.0/25 - still a "class C" address but because of the /25 it has 2 available subnets which have 126 host addresses available each. So here the networks would be; 1st subnet 192.168.1.1 - 192.168.1.125 subnet 255.255.255.128 192.168.1.0 - indicates the network subnet 192.168.1.126 - broadcast address 2nd subnet 192.168.1.128 - 192.168.1.254 255.255.255.128 192.168.1.127 - indicates the network subnet 192.168.1.255 - indicates the broadcast address Domains also have a hierachical structure; Forest----->domain (you can multiple domains in a forest) | |------>domains can have subdomains within them. Such as this... top level domain = pcworld.co.nz subdomain = pressf1.pcworld.co.nz etc So coming to your question about setting up subnets within a domain... If I understand correctly you're referring to having each of your DC's on a "different" network? To achieve this you setup your subnets on your network - i.e. configure routers and switches with the various networks, VLANS (if applicable) etc. Then on your primary DC you need to add these configs to DNS/DHCP etc and also configure statics routes on your network interface. If you're using replication the DNS/DHCP settings will filter through to the other DC's if your secondary is a backup to your primary then the DNS/DHCP configs should be the same. Note the network interfaces will have different configurations in terms of IP address and each DC should have a static route added for the other 2 networks. You shouldn't need to add the default route for that network as it willalready have been added when you configured the network interface at the start. So you can have each of your servers on 3 different subnets but still have them able to "communicate" with each other via routing configs etc. Caveat I'm no expert but this is how I've done it at home and have not had any issue. Though to be fair it wasn't exactly an advanced config I was going for. Good luck Hey chiefnz thanks so much for help , much appreciated . I do understand it now . So thanks once again . |

| 1406999 | 2015-08-24 04:18:00 | Do you sit the exams for a fee, chief? Uuummm generally, all vendor exams are at a cost yes. If the vendor does mandate a compulsory course (like VMware does) some providers such as Auldhouse computing will include a single "shot" at the exam as part of the course fees... and yes you guessed it these courses are like $5K and up possibly more nowadays. Microsft doesn't mandate sitting a compulsory course for it's certifications (yet) though one of the biggest differences is that "most" MS certifications require more than one exam... the only caveat here is the MS Certified Professional accreditation which you automatically gain after successfully completing any applicable MS technology exam. This is kind of neat because it gives you some sense of accomplishment as you go from exam to exam the other thing is MS certifications don't really expire but the technology platform the certification is for can become obsolete - so you do get at least 5-7 years "use" out of your certification. |
