File Server/AD Migration

11 de Novembro de 2009 – 11:42

Here’s the setup:
Single server that is a DC, DNS, DHCP and WINS server. Also hosts all file shares (user directories and shared folders) and printer shares.

Move everything over to the new server. Here’s how:

1.Build your new server
First thing, build you new server with the latest Windows 2003 software (we’ll stay on 2003 as that’s the most common right now). We’ll call the old server OLDDC and the new one NEWDC.

Give yourself a large C: partition, at least 25gb. The rest of can be partitioned into the D: drive. I don’t like to create a lot of partitions because they just cause more overhead for little purpose. ALWAYS keep your OS and data separate though!

As for the server, most places up through 100 users can easily get by with a single RAID controller running RAID5. You’ll see plenty of debate over this (RAID6, RAID10, etc) but I’ve had good luck with this configuration. 4gb of RAM for Windows Standard.

2. Promote the server to be the DC

a. Insert your new server into the domain. Make sure to install DNS, DHCP and WINS before continuing.
b. Run “DCPROMO” and make this a new DC in your domain.
c. Record your AD Recovery password!
d. Wait at least an hour or 2 to make sure everything gets replicated and you AD settles down.

DHCP Database Topics

11 de Novembro de 2009 – 10:47

Perhaps you have never given the DHCP database a thought. Well the time may come where you need to backup, reconcile or compact the DHCP database. At the very least, I expect you will want to check your lease statistics.

DHCP – Display Statistics

Bizarrely, I find ‘Display Statistics’ the most difficult tab to find on the DHCP server. This is because it’s the first item on the menu, and is often masked by the very highlight that should attract me. I just hope that you are not afflicted by this blind spot. In any event, Display Statistics is one of the most interesting and rewarding items on the DHCP menu.

Display Statistics is available at both the server and the scope level. My first thought is, ‘How many leases are left?’ Next, I look to see if there have been any NACKS or lease declines. See the screen shot to find the Display Statistics… menu.

SQL Server: Database Snapshot (Transact-SQL)

22 de Setembro de 2009 – 14:36

Qualquer utilizador que possa criar uma vbase de dado, pode criar um Snapshot. A única maneira de o fazer é usando Transact-SQL.

Com base no tamanho actual da base de dados fonte, garantindo que você tenha espaço em disco suficiente para armazenar o snapshot da base de dados. O tamanho máximo de um snapshot da base de dados é o tamanho da base de dados origem na criação do snapshot.

Este exemplo cria uma base de dados snapshot, na base de dados AdventureWorks. O nome dosnapshot, AdventureWorks_dbss_1800, e o nome do arquivo do seu arquivo esparso, AdventureWorks_data_1800.ss, indicar o tempo de criação, 6 (1800 horas).

Exemplo:

CREATE DATABASE AdventureWorks_dbss1800 ON
( NAME = AdventureWorks_Data, FILENAME =

'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\AdventureWorks_data_1800.ss' )

AS SNAPSHOT OF AdventureWorks;
GO

A extensão . ss utilizada nos exemplos é arbitrária.

Clonezilla

21 de Setembro de 2009 – 11:04

What is Clonezilla ?

You’re probably familiar with the popular proprietary commercial package Norton Ghost®, and its OpenSource counterpart, Partition Image. The problem with these software packages is that it takes a lot of time to massively clone systems to many computers. You’ve probably also heard of Symantec’s solution to this problem, Symantec Ghost Corporate Edition® with multicasting. Well, now there is an OpenSource clone system (OCS) solution called Clonezilla with unicasting and multicasting!

Clonezilla, based on DRBL, Partition Image, ntfsclone, partclone, and udpcast, allows you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition).

Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. At the NCHC’s Classroom C, Clonezilla SE was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting!

Features of Clonezilla

Free (GPL) Software.
Filesystem supported: ext2, ext3, ext4, reiserfs, xfs, jfs of GNU/Linux, FAT, NTFS of MS Windows, and HFS+ of Mac OS. Therefore you can clone GNU/Linux, MS windows and Intel-based Mac OS, no matter it’s 32-bit (x86) or 64-bit (x86-64) OS. For these file systems, only used blocks in partition are saved and restored. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla.
LVM2 (LVM version 1 is not) under GNU/Linux is supported.
Multicast is supported in Clonezilla SE, which is suitable for massively clone. You can also remotely use it to save or restore a bunch of computers if PXE and Wake-on-LAN are supported in your clients.
Based on Partimage, ntfsclone, partclone, and dd to clone partition. However, clonezilla, containing some other programs, can save and restore not only partitions, but also a whole disk.
By using another free software drbl-winroll, which is also developed by us, the hostname, group, and SID of cloned MS windows machine can be automatically changed.

Links não abrem no Internet Explorer e MS Word

21 de Setembro de 2009 – 10:37

Quando se clica num link no Outlook ou no MS Word e este não abre no browser, este é divido, normalmente ao facto de os links não estarem associados ao Internet Explorer.

Podemos para o efeito executar o seguinte Registry Fix:

ie_default_browser

Esta alteração ao Registry apenas funciona se tiver o Internet explorer instalado e na seguinte localização:

[C:\Programas\Internet Explorer], caso contrário pode editar o ficheiro no bloco de notas e actualizar a localização.
