One of the routers you have to connect to internet, another one you have to connect to the first one using a lan cable. You can use any of lan ports of the first router to connect the second one (except internet port, usually it's marked as WAN or similar to). The lan cable should be connected to the WAN port on the second one. Only in such case it works properly.
What are the advantages of leased line networking?
-1. Bandwidth on Demand - Not possible(Dynamic Bandwidth allocation not possible)
§2. As the organization grows, number of links becomes more.
3. Network becomes more complex and it becomes difficult to maintain the reliability.

As we are using a class B network for the Subnetting and we have to make a total of at least 130 subnetworks...
so, class B default subnet mask is 255.255.0.0 or 16 bits for networking
and we have to make 130 sunets. so it will come under the block size of 256 or we need 8 bits more to make 130 subnets.
so our answer is 16+8=24
ie, we will use subnet mask of 255.255.255.0 for this class B address.
I might be wrong, but I think Enable CDP on the switch and Turn off unnecessary services.

What port does Remote Desktop use Does everything go over port 3389?
Port 3389 is the only port you need to open. Windows will attempt to stream sound through User Datagram Protocol (UDP) first. If no port is available for UDP, sound will stream through a virtual channel in Remote Desktop Protocol, which uses port 3389. http://www.microsoft.com/windowsxp/using/mobility/rdfaq.mspx

How can you assign private ip address to system?
Start->Control Panel->Network Connections, right click on the network adapter to assign ip address for, ->Properties. On the tab General i the list This connection uses following items, locate Internet Protocol (TCP/IP), click on it and then click on Properties. On the tab general you will see options to assign Ip addresses. First, obtain an ip address automatically;, second, use the following ip address. Either of them can help you to get a private ip address. First can help when you have a router with DHCP server, second when you don't have a DHCP server in your network. When you change ip addresses you internet might stop to work depending on your interprovider settings.
Star Typology The third topology is the Star. This is the most common, and most familiar LAN topology in use. In a Star setup, all devices connect to a central hub. Each device accesses the LAN independently of the others. That is, unlike a Ring or Bus, on a Star, there is no backbone that carries all the data to all the stations. The hub functions as a pseudo-backbone, but without the electronic requirements of a Ring or Bus. In a Star, hubs can be interconnected, to allow for greater flexibility of configuration and load balancing. The number of stations on a given Star is limited by the size of the hub, and available bandwidth. Similar to the Bus and Ring, bandwidth on a Star is shared by all stations. brought to you from: http://www.mactech.com/articles/mactech/Vol.16/16.06/Jun00GettingStarted/index.html 10/06/2009

Are you sure its the AD that's freezing up and not the server...?? I'd say more than likely an important file has become corrupt. Try exporting everything in the AD then delete, re-install and import the files. If the problem continues you may want to have a look at your DNS, the two of these work together. Though Ive never seen this a DNS causing this, but I guess its possible.
Also sometimes a badly designed AD can put your memory usuage way up. Could be putting pressure on your server.
Formula in a full mesh network?
Where n = number of nodes The number of connections in a full mesh = n(n - 1) / 2
Formula to determining the connections in a full mesh network?
Where n = number of nodes The number of connections in a full mesh = n(n - 1) / 2
What is routing and switching?
