Change DNS servers on the stations using a script

This is useful when we are performing a server migration, in the event that we are going to change the IP address DNS servers or the server DNS server, we must change its DNS servers in all positions. The posts may be configured with a dynamic IP address so the change is very simple and we will change it only on the DHCP server. But.. What happens if our posts have a fixed IP address? That we should change the 'Preferred DNS Server'’ and the 'Alternate DNS Server'’ or manually or with the help of a simple script that we can put in the login of the posts through a GPO.

Migrate DHCP Server to Another Server with DHCPexim

This procedure explains how to move the DB from our DHCP to another server, It doesn't matter the S.O. of origin, how if we migrate from NT4 to NT4, NT4 to 2003, a 2000, of 2003 to 2003… The first thing we will need is the DHCPexim, The tool that migrates, download from AKI. And we start installing it on the server from which we want to migrate the DHCP service, then once exported to a text file we will install the DHCPexim on the destination server to import that file, More details:

Configuring DHCP (Dynamic Host Configuration Protocol – Dynamic Host Configuration Protocol

When we set up a net, Or when we migrate one and it has a fixed address, we remember how good it would be to have a DHCP server set up and forget about the issue of going post by post modifying any network data. DHCP is used to save a network administrator work, IPs are configured from the server, a range of IP addresses to be assigned to the positions is established and that's it, We can also include, all the data that interests us apart from the IP, such as, What is the gateway, DNS, WINS and many more. We can assign the duration of the IPs in the clients, by default are 8 days. We can reserve IPs by MAC addresses. And see the list of assigned IP addresses.

Distributed File System – DFS + Replication – DFS-R

One of the new features brought by Microsoft Windows 2003 RC2 is the new console for configuring DFS and configuring replicas that now work perfectly. The most important thing is that you have to have the RC2 version on the servers that are going to have the DFS root. To upgrade to the RC2, just install the CD2 of the distribution, install the new components. And if you want to update the domain to the version 2003 RC2, you have to execute the ADPREP that also comes in CD2 (adprep /forestprep). This document explains the DFS for the Windows version 2000 or 2003 – HERE.

Distributed File System – DFS – Distributed File System

This service is basically for when a company has more than one server and they are file servers. Let's say that a company works all the employees against a server and it goes down, Until the server is lifted, it is impossible for employees to continue working. With DFS it is possible that if the file server goes down they can continue to work against another server. And employees shouldn't be working against the server this way: SERVERFOLDERocumento.eso sino: DOMAINFOLDERAocumento.eso. What this does is it will be working against one server and it will replicate the data against the other server. In the event of a failure of one server, work can continue on the other.

Network balancing: Round Robin DNS + NLB

This document explains how to balance an IP address or hostname, It's ideal if we have a web host and we want to have a balance of it, Mirroring the web page on both servers (also serves for OWA), or the profits that can be assigned to it. There are two methods for this, “Round Robin” or NLB (Clúster de equilibrio de red o Network Load Balancing):
