Windows Server 2003 Tutorials, Visual and Step-by-Step

Welcome to my Windows Server 2003 tutorial website! Here you will find visual, step-by-step guides that can help you on your Windows Server journey. Everything has been tested personally, on a default installation. I cannot guarantee that the guides will always work, but they should on most configurations. Articles prefixed with "MS KB:" are links to Microsoft Knowledgebase articles ( http://support.microsoft.com ) that I have written.
Early adopters of Microsoft’s new Vista operating system may notice that it will not connect to Samba share folders out of the box. This will be a bit of a pain for many enterprise customers. The technical reason is because Microsoft Vista’s default security policy is to only use NTLMv2 authentication. According to a Google search Samba doesn’t support this yet. Update: Some readers have pointed out that NTLMv2 authentication is supported in Samba 3.0. However, this certainly wasn't an option to get this running in my instance. http://www.techrepublic.com/article/get-vista-and-samba-to-work/6353849

Creating and Using a self signed SSL Certificates in debian

This document covers a very specific, limited purpose, but one that meets a common need: preventing browser, mail, and other clients from complaining about the certificates installed on your server. Not covered is dealing with a commercial root certificate authority (CA). Instead, we will become our own root CA, and sign our own certificates. Why be our own root CA?

Remove the Microsoft .NET Framework Assistant (ClickOnce) Firefo

Remove the Microsoft .NET Framework Assistant (ClickOnce) Firefox Extension The Microsoft .NET Framework 3.5 Service Pack 1 update, pushed through the Windows Update service to all recent editions of Windows in February 2009, installs the Microsoft .NET Framework Assistant firefox extension without asking your permission . This update adds to Firefox one of the most dangerous vulnerabilities present in all versions of Internet Explorer: the ability for websites to easily and quietly install software on your PC. Since this design flaw is one of the reasons you may've originally chosen to abandon IE in favor of a safer browser like Firefox, you may wish to remove this extension with all due haste. Unfortunately, Microsoft in their infinite wisdom has taken steps to make the removal of this extension particularly difficult - open the Add-ons window in Firefox, and you'll notice the Uninstall button next to their extension is grayed out! http://annoyances.org/exec/show/article08-600
Sophos recommends enabling the MTA-level IP Blocker as part of an overall strategy to optimize PureMessage performance. If you want to authenticate connections using SMTP-AUTH while MTA-level blocking is enabled, you must modify PureMessage Postfix (SMTP-AUTH is not supported for external Postfix installations nor for any version of sendmail). When configured as described below, your system permits access for any IP address contained in the $mynetworks parameter, and then checks to see if it's an authenticated connection. http://www.sophos.com/support/knowledgebase/article/40280.html

For a Mac, visit System Preferences – Sharing and enable Remote Login. While you are in this window you can also enable Screen Sharing if you want to be able to access the machine using the VNC protocol. If you are running Linux, a quick Google search will turn up plenty of guides or you can get started here .

It happens to everyone sooner or later: a split second after you hit Enter you realize your mistake, but it's too late; you just deleted a valuable file or directory for which no backup exists. Or maybe you have a backup, but it's a month old... and in shock you see the past month flash before your eyes as you realize in pain what you'll have to do all over again... Fortunately, you remember that files are never really deleted, at most overwritten by new content. So, you remount the disk read-only as fast as possible. But now? http://www.xs4all.nl/~carlo17/howto/undelete_ext3.html

Searching for the QoS Holy Grail

http://www.networkworld.com/reviews/2002/0603rev.html With the convergence of voice, video and data in enterprise networks, and the increasing need to cut travel costs, both voice over IP and videoconferencing are becoming increasingly important. When coupled with the ever-present requirement that critical enterprise applications perform at their best, even in a fiscally tight environment, the days of "best effort" service are rapidly disappearing. Quality of service (QoS) is actually an ad hoc collection of technologies and techniques.

by Mirko Zorz - Wednesday, 14 March 2012. The past 10 years represent a very interesting timeframe for reviewing vulnerability disclosures and ensuing changes that continue to affect risk management in IT organizations around the world. Vulnerability disclosures across the industry in 2011 were down...

Using PAM to Block Brute Force Attacks | MDLog:/sysadmin

The idea to use PAM (Pluggable Authentication Modules for Linux) to block brute force attacks sounds like a good idea, right? After all, we are using PAM for most of the authentications mechanisms, so adding a module to check against repeated failures would be great. Surprisingly even if this sounded like something normal, I found only one PAM module that was written for this purpose. This is called pam_abl and you can find it here: http://hexten.net/pam_abl In order to use pam_abl we first need to install it on our system.
In the previous article of this series, we started reviewing high availability and scalability enhancements in SQL Server 2005 (based on its recent Beta 2 release) by discussing database mirroring. In this article, we will continue exploring the same area of functionality, shifting our attention to failover clustering. We will also provide comparison of both features, which should help in recognizing the types of scenarios for which each of them is better suited. Failover clustering has been supported since SQL Server 7.0 so it is not surprising that its latest implementation is a combination of already familiar (and stable) technology with a number of useful improvements.
