Good catch on point 16. Yes it should be 'RESET PASSWORD ON SERVER <SERVERNAME><br />

Tips for Active Directory Restores

by gary In reply to Tips for Active Directory ...

Clive, in your example the quickest fix is FORMAT C:<br /><br /><br />Wipe the server, re-install the O/S then run DCPROMO and make it a second DC again.<br /><br />You will then need to run NTDSUTIL to do a METADATA clean up.

Newsgroups

by gary In reply to The Bit Bucket

<div xmlns="http://www.w3.org/1999/xhtml">I often wonder just how many people who 'found' the net after Tim Berners-Lee brought us the web actually know about newsgroups?<br />
<br />Well, Newsgroups are still very much alive and well. There are several companies they have public news servers to allow folk to talk about specialist topics. I'm amazed just how many of these companies decide to host thier newsgroups on IIS.<br />
<br />Whilst IIS does the job it severly lacks functionality, has a VERY annoying bug and its clunky to migrate - even between the same version of IIS!!!<br />
<br />
<a href="http://www.elbiah.de/hamster/index.htm">Hamster Classic</a> is a free NNTP server for Windows that will sit quite nicely on your network and connect to multiple NNTP servers. It is very handy where you want to distribute a subset of external news groups (e.g. the public Microsoft ones) and host your own internal groups.<br />
<br />Hamster can do all this and more but it does have several down sides:<br />
<br />
<ul>
<li>It doesn't install as a service.</li>
<li>It has no scheduling mechasim so you need an external application to 'force' it to collect data from news servers and purge old data.</li>
<li>Most configuration is via text files.</li>
</ul>
<br />Deepsite these annoyances it's actually a very nice piece of software that once configured just sits there and works.</div><div class="blogdisclaim"><a href="http://www.gdwnet.com/blog/2006/06/newsgroups.html">This post originally appeared on an external website</a></div>

Password Policies on Domain Controllers

by gary In reply to The Bit Bucket

<div xmlns="http://www.w3.org/1999/xhtml">Many times now I have seen the same errornous answer to the question of <em>"How can I give people in different OU's different password policies?"<br />
<br />
</em>You cannot.<br />
<br />Password policy is function of the DOMAIN policy and not an OU policy therefore you need to think carefully about your password policies because this will affect your Active Directory design considerations.</div><div class="blogdisclaim"><a href="http://www.gdwnet.com/blog/2006/06/password-policies-on-domain.html">This post originally appeared on an external website</a></div>

VMWare Server functionality

by gary In reply to The Bit Bucket

<div xmlns="http://www.w3.org/1999/xhtml">I suspect that like many of you VMware plays a big part in testing new apps/systems and other fun toys that are released on an almost daily basis.<br />
<br />For sometime now I've been using VMWare workstation. The ability of workstation to be able to create network teams and multiple snapshots can be quite invaluable. The only functioanlity missing is the ability to run workstation on a server and be able to connect to it via a console or web page.<br />
<br />GSX (now VMWare Server) has this functionality and is freely available. Taking the plunge I removed VMWare workstation and have started using the free VMWare server. For me, the ability to be able to connect to the server via a webpage and control my machines outweighs the very small disadvantages.<br />
<br />In fact, because of the way VMWare networking can be configured using custom adapters it's quite easy to create a VERY similar level of fucntionality in VMWare as already exists in VMWare workstation.<br />
<br />As I am building a full test network using nothing but a Windows 2000 server and a copy of VMWare Server I wil blog various tips and tricks that I find as I build the test network.</div><p><div class="blogdisclaim"><a href="http://www.gdwnet.com/blog/2006/06/vmware-server-functionality.html">This post originally appeared on an external website</a></div>

Webmin - A Linux Administration Tool

by gary In reply to The Bit Bucket

<div xmlns="http://www.w3.org/1999/xhtml">As part of my VMWare test network I have a Linux Fedora Core 5 install acting as a router and firewall. The linux install is as lightweight as possible so everything runs in INIT 3 mode (no KDE or GNOME because it's not needed).<br />
<br />For administration I'm using webmin. This VERY clever web based administration tool is great for quickly changing configurations and performing daily tasks. It's updated every few months and via the webmin console it's quite easy to keep webmin updated.<br />
<br />Webmin can be downloaded from <a href="http://www.webmin.com">here</a>
<br />
<br />Installation is easy. I tend to use WINSCP to copy the file to the /tmp directory then run the installation by using Putty to SSH onto the server then typing the command:<br />
<br />rpm -i webmin-1.280-1.noarch.rpm<br />
<br />I'm in the process of creating a Redhat unattend built similar to the ones I use for Windows that will allow all of these stuff to be done automatically. More on this soon.<br />

Deploy MS06-025 if you have not done so

by gary In reply to The Bit Bucket

<div xmlns="http://www.w3.org/1999/xhtml">Microsoft have just issued an official security advisory telling folk to install <a href="http://www.microsoft.com/technet/security/Bulletin/MS06-025.mspx">MS06-025 </a>if they have not done so.<br /><br />Exploit code for this vulnerability has been released and is publicly available.<br /><br /><a href="http://www.microsoft.com/technet/security/Bulletin/MS06-025.mspx">MS06-025</a> patches a couple of security holes that are found in the RRAS service on Windows 2000, XP and 2003 machines. There are some caveats to be aware of and these are documented in <a href="http://support.microsoft.com/kb/**1280">Microsoft KB **1280</a> <br /><br />This patch replaces some interesting files such as ipsec.sys so if your using RRAS for VPN style work you will need to do some additional testing.<br /><br />More information as it comes.....</div>

Active Directory DNS zones

by gary In reply to The Bit Bucket

Almost everyone who has played with Active Directory knows that DNS is important. In fact, DNS is so important to Active Directory that it simply is a must for Active Directory to work.

By default Active Directory creates a Active Directory integrated DNS zone. This is quite a clever method for replicating within an Active Directory domain as any changes to DNS are replicated to other DNS servers<p><div class="blogdisclaim"><a href="http://www.gdwnet.com/blog/2006/07/active-directory-dns-zones.html">This post originally appeared on an external website</a></div>
