I have a windows server on a single segment, which has a superscope configuration. Computers are receiving IP addresses from scope 2 but they are ynable to browse server resources or access the internet. Hi, You need to add another IP to the internal interface of your router so clients can access the internet. This IP will be the gateway for the second scope. For clients to access resources you need a router between the two segments, or just add another IP from the second segment on the server if this is a small environment and everything is going on the same switch.

Customizing the Default Local User Profile before imaging. Im not just so savvy on the router part. Reply Thanks man! Reply I will appreciate if you come back here and leave a comment after you solve this just so others can benefit from it. Thanks Reply Hi, How many scopes can be created in super scope.
Reply Hi, Yes, the second scope will start giving IP addresses to clients only when the first scope is depleted. But the IT crowd isn't in the same celebratory mood. The reason? They're running on empty or, more precisely: the DHCP server is. The problem is that the DHCP server is fast running out of IP addresses to dish out to all the new computers being added to serve your company's growing staff complement.
There's an exclamation mark hanging like an ill omen over the DHCP server icon Figure A , an indication that you're dangerously close to the end of the available address pool. When the company started out as a small business with 50 PCs three years ago, the IP addresses a Class C subnet offered seemed more than enough for a long time. But now it's a different story. There are just eight unassigned IP addresses left.
As the responsible network admin, what are your options? You could lobby for another physical LAN and thus another subnet , but that would mean you'd have to convince the boss to buy a router or another one if you already have more than one physical LAN and maybe another DHCP server.
Changing to another IP address class--maybe Class B, which will provide you with more addresses--is another possibility, but again not a very attractive one. This time you'll have to justify purchasing this address range from your ISP and then face the prospect of migrating from the existing address range scope to the new one. Thankfully, there's a much simpler solution--using a superscope. What's a superscope? A kind of mother of all scopes. It allows you to add more than one scope called child scopes, or member scopes under one umbrella.
Let's go ahead and create a superscope for the scenario described above. We'll assume DHCP is set up to use the scope We want to add another scope from the same class Class C , so let's use But first we need to create a superscope.
Here's how:. The final screen of the wizard informs you that you have successfully completed the New Superscope wizard and gives you the details Figure D. If you go back into DHCP, you'll see that the new superscope has been created.
Superscope allows a DHCP server to provide leases from more than one scope to clients on a single physical network. Scopes added to a superscope are called member scopes. When more than one logical IP network is used on each physical subnet or network, such configurations are often called multinets. In multinet configurations, DHCP superscopes can be used to group and activate individual scope ranges of IP addresses used on the network.
In this way, a DHCP server computer can provide leases from more than one scope to client on a single physical network.
Superscopes can resolve certain types of DHCP deployment issues for multinets, including the following situations:. The available address pool for a currently active scope is nearly depleted, and more computers need to be added to the network.
