  • Windows 8 Restore Problems

    - by Joe
    I created a Windows 8 system image backup on a separate drive before I installed Linux, and during the Linux installation process I accidentally wiped out Windows. I now want to restore my Windows 8 backup that I have on the separate drive. I created a repair USB stick and I followed the directions according to this article. After selecting the image on the hard drive, I get this error: "To restore this computer, Windows needs to format the hard drive." I don't know what this means! The drive partitions are different now then they were when I backup up, so I don't know if that matters. I re-installed Windows and I can restore my files from this backup, but I don't think this covers the registry, etc. I want a full restore. Does anyone know how to fix this problem, or how to restore in a different way? Thanks!

  • Windows 8 doesn't play nice when dual booting with Windows 7?

    - by leaf68
    I have Windows 7, and Windows 8 on my laptop. I have Windows 7 set as my default, and it asks me each time if I want to boot with 7 or 8. When I boot with Windows 8, then restart my computer, it opens up to the Windows 8 boot screen, and sets Windows 8 as my default. How can I stop it from changing my default because it's a hassle to change it each time I want to use Windows 8. EDIT: I forgot to mention that in only happens sometimes. It usually doesn't change it when I restart, but it sometimes changes it when I completely shut it off.

  • How to make HOME or END keys work in mc running on OS X (ssh)

    - by Sorin Sbarnea
    I installed MacPorts on OS X 10.5 and I found out that when I connect to the computer using SSH and use mc - Midnight Commander - the HOME and END keys do not work. I have to mention that I'm using putty and I am able to use the keyboard very well on Linux machines like Fedora, Ubuntu,... Here is putty keyboard configuration (a configuration I found to be optimal over time): Backspace key: 127 Home/End keys: Standard Function keys: Xterm R6 Cursor keys: Normal Numpad: normal Terminal type string: xterm-color I'm looking for a command line solution/script that does these changes, this make much easier to create a prepare OS script for configuring a new OS.

  • Apache localhost problem

    - by hart1994
    I have set up Apache on my Windows 7 PC. Now I have it working fine on the PC, by going to localhost or the IP (192.168.1.71). However when I go to my Mac I try to connect to it via its IP and it doesn't connect. I have also tried this on another computer. Oops! Google Chrome could not connect to 192.168.1.71 Now is there something wrong with the code in the Apache httpd file? EDIT: I have also tried to ping the IP address and it works fine.

  • Windows Security Center Service is missing

    - by TheTub
    I am trying to fix a Windows 7 machine here that has been infected with all kinds of Malware. I have removed all of them as far as I can see but I am stumped by one last task. One little bugger managed to remove the Windows Security Center service from the list of Windows services. So I cannot start it or set to automatically start. At the moment I cannot get the Windows firewall to turn on or any anti-virus software. The security center shows the following image when I try: Does anyone know how to add this back to the list of services so I may set it to start. I don't have a backup of the registry for this computer (it's not mine). Many thanks TT

  • What are the minimum hardware requirements for the latest version of Android Jelly Bean OS?

    - by Stom
    I searched around, and there's no information that points exactly to the suggested, minimum, or otherwise dated information containing specifications on this. I want to install a newer version of Android on an older ZTE-X500 MetroPCS smartphone. However, I'd like to know the backwards compatibility in regards to using a newer featured OS with lackluster, limited hardware compared to today's smartphones, such as Galaxy S4. However, I still wish to do this. If Jelly Bean is too demanding, I will set up Honeycomb, or get a modified Honey Comb ROM, or tweak the source to my preferences. However, nothing outlines the specifics of the "system requirements" it suggests for optimum performance, such as RAM, processor speed, processor features, and/or any other features, like DMA, video circuit advancements, and/or sound and special hardware requirements noted as well. Please, if you will, point me to a source that mentions this, and please tell do not link me to any PDF file formats. Thank you. PS: I'm a computer programmer.

  • Streaming flash video does not work on my Mac OS X

    - by dehmann
    Flash videos do not work properly on my Mac. On this Vimeo video, for example, it shows only the beginning frame, and audio stutters like crazy, playing audio for a quarter second or so, then silence, then playing again, etc. I have Flash version 10,0,42,34 on Mac OS 10.5.8. It's a PowerBook G4 (PPC). I tried it in Firefox 3.5.5 and Safari 4.0.3. I tried reinstalling Flash, restarting the computer, and using a fresh user profile in Firefox (so that no extensions are interfering with the site), loading the video fully before playing, but nothing helps. I noticed that youtube videos work better, once loaded enough, although the picture does halt briefly once every 10 or so seconds, even when it's fully loaded.

  • How to get average of multiple time series

    - by Supun Kamburugamuva
    I have few computers running. I want to get the average CPU usage of these computers and plot it as a graph. So I've collected CPU usage in regular intervals in these machines. So for each computer I have a data set of time and CPU usage. But the times at which CPU measurements are taken in different machines are not in sync. For example in 1st machine CPU may be measured in time 1, 5, 9. In the second machine CPU may be measured in time 2, 5, 8. I want to get an average data series from these different data sets. Could you point me to some resources? Thanks - Supun.

  • How do I solve VirtualBox error 0x80004005?

    - by maria
    Hi I was trying to run Windows XP under Virtual Box (host system Ubuntu 10.04) and I've got an error message saying: Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Re-setup the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary. This is terminal output: maria@maria-laptop:~$ sudo /etc/init.d/vboxdrv setup * Stopping VirtualBox kernel modules * done. * Uninstalling old VirtualBox DKMS kernel modules * done. * Trying to register the VirtualBox kernel modules using DKMS * Failed, trying without DKMS * Recompiling VirtualBox kernel modules * done. * Starting VirtualBox kernel modules * done. After that I can run XP on Virtual Box, but when I try to log into user's account, I have the message that I have to register XP (I haven't done it yet, as each time I was cliking on pop-up window suggesting registration, nothing was happening). I click that I want to register it now and appears the message about error 0x80004005, which prevents Windows to check the license for that computer (the message is in Polish, so I don't post it here...). I forgot to install DKMS first, but I've done it after. What should I do to run virtual machine? It was using it already, the problem occured only today. Thanks for any suggestion

  • Windows 7 - can't uninstall application as admin

    - by James Atkinson
    I'm trying to uninstall Microsoft Virtual PC 2007 from my Windows 7 machine. Logged in as administrator, when I attempt to uninstall I get a messagebox stating "The system administrator has set policies to prevent this installation." Excuse me? No I haven't. Immediately following, another messagebox displays: "You do not have sufficient access to uninstall Microsoft Virtual PC 2007. Please contact your system administrator." I didn't do anything unusual when installing or setting up the software. Just normal home use computer. Any ideas on how to remove this software?

  • What is "WinZip Registry Optimizer" and whatever happened to WinZip?

    - by Aerovistae
    So some file the other day told me I needed something like WinZip to unzip it. I was tired and didn't think about what I was doing as I cheerfully downloaded it, because I remember years and years ago I used to use it all the time. But then I found it barely worked at all in the first place, would only work for a few days before I had to start paying for it, and worst of all, forced a supplementary install of something called "WinZip Registry Optimizer." After installing 7-zip and getting rid of WinZip, I found this Registry Optimizer continually popping up and telling me my computer was loaded with viruses and errors and I just had to buy it. This obviously means the Optimizer is a virus unto itself, and I uninstalled it from the control panel. But still, it bothers me. I googled it and found the WinZip site proudly offering downloads of this program, this spamware. What happened? Why has a once-mainstream software developer been reduced to this?

  • Can't connect disk management to remote XP PC from local Win7/Server 2008

    - by Grez
    Scenario as follows: support technicians using Windows 7 PC's or Server 2008 terminal server are unable to connect Disk Management MMC snap in to a remote PC when the remote device is running Windows XP. "Disk management could not start Virtual Disk Service (VDS) on ". This can happen if the remote computer does not support VDS, or if a connection cannot be established because it was blocked by Windows Firewall." Connecting from another XP machine or 2003 server to the same XP machines works fine. Even connecting from XP/2003 to the Win7 or 2008 server works fine. Windows firewall disabled on all devices. I'm guessing this is something to do with the fact that XP uses logical disk manager service whereas Win7/2008 use Virtual disk manager service. But there doesn't seem to be any way to use logical disk manager service from 7/2008 to connect to XP...

  • Read All The Books from Skyrim on Your Ebook Reader

    - by Jason Fitzpatrick
    If you’re a fan of the wildly popular RPG game Skyrim, you’ve undoubtedly discovered the books sprinkled throughout the Empire. This collection brings them all together for out-of-game reading. Blogger and Skyrim fan Capaneus enjoyed reading the in-game books so much (found on the shelves of homes and otherwise scattered throughout the virtual world) that he did a little digging in the game files to turn up the source of the books. It turns out he didn’t have to dig too deeply, the files are stored as text documents (and if you have a copy of the game installed right now you could easily open them up yourself). He took those text files and carefully formatted them as MOBI and EPUB files, well suited for use on an ebook reader or tablet. Hit up the link below to grab a copy for your own perusal. While we can’t see this lasting long in the age of copyright enforcement and litigation we’d like to think the company behind Skyrim will see the utility of sharing the books (existing Skyrim owners will enjoy it and the curious will likely be inspired to buy the game).

  • How to keep Flash secured with EMET?

    - by Indrek
    I use EMET to secure a number of applications on my computer - web browsers, Office suite applications, PDF readers, as well as Adobe Flash. Overall it's working great, except that the Flash executables contain the version number in the file name, so every time there's an update, the file names change and I have to remember to re-add them manually to EMET. Is there a way to streamline this process? EMET does support wildcards, but only in the path itself, not the file name, so something like %windir%\system32\Macromed\Flash\*.exe wouldn't work. Is there any other way to add a whole folder to EMET so that any new executables in that folder are automatically secured?

  • Going from imagex/AIK to WDT

    - by lross1309
    I was looking learning Windows Deployment Toolkit. I have been using AIK to create answer files and sysprep to clean the referece computer and imagex to capture and apply images. I have some .wim files I need to keep (they also have an answer file in them). I was wondering, if I start using WDT, can I import these images and have WDT deploy them or do I have to start over with capturing the images using WDT? If I can import, how do you deploy them in the same manner that imagex would use the images internal answer file using WDT? Leon

  • Windows 7 recognises the wrong router.

    - by Henry
    I have a cable router connected to my cable ISP. On the LANs are 4 computers, one of which is a dual boot XP/Win7 machine. I was given an ADSL wireless router which I connected to one of the LAN sockets on my cable router. I don't have an ADSL connection. All the machines connect correctly, some wirelessly, when my dual boot machine is in XP or off. However, when I go into Win 7 on that machine it finds the ADSL router and wants to connect through that (there's no ADSL connection) instead of my cable router and modem. I've turned DHCP off on the ADSL modem and even tried bridging its connections but neither of these have any effect. To get 7 connected, I have to either disconnect the ADSL router, or switch it off. Remember, the SAME computer on the same LAN works perfectly with the same router connected in XP! How then, can I get Win 7 to recognise the correct router?

  • CEN/CENELEC Lacks Perspective

    - by trond-arne.undheim
    Over the last few months, two of the European Standardization Organizations (ESOs), CEN and CENELEC have circulated an unfortunate position statement distorting the facts around fora and consortia. For the benefit of outsiders to this debate, let's just say that this debate regards whether and how the EU should recognize standards and specifications from certain fora and consortia based on a process evaluating the openness and transparency of such deliverables. The topic is complex, and somewhat confusing even to insiders, but nevertheless crucial to the European economy. As far as I can judge, their positions are not based on facts. This is unfortunate. For the benefit of clarity, here are some of the observations they make: a)"Most consortia are in essence driven by technology companies making hardware and software solutions, by definition very few of the largest ones are European-based". b) "Most consortia lack a European presence, relevant Committees, even those that are often cited as having stronger links with Europe, seem to lack an overall, inclusive set of participants". c) "Recognising specific consortia specifications will not resolve any concrete problems of interoperability for public authorities; interoperability depends on stringing together a range of specifications (from formal global bodies or consortia alike)". d) "Consortia already have the option to have their specifications adopted by the international formal standards bodies and many more exercise this than the two that seem to be campaigning for European recognition. Such specifications can then also be adopted as European standards." e) "Consortium specifications completely lack any process to take due and balanced account of requirements at national level - this is not important for technologies but can be a critical issue when discussing cross-border issues within the EU such as eGovernment, eHealth and so on". f) "The proposed recognition will not lead to standstill on national or European activities, nor to the adoption of the specifications as national standards in the CEN and CENELEC members (usually in their official national languages), nor to withdrawal of conflicting national standards. A big asset of the European standardization system is its coherence and lack of fragmentation." g) "We always miss concrete and specific examples of where consortia referencing are supposed to be helpful." First of all, note that ETSI, the third ESO, did not join the position. The reason is, of course, that ETSI beyond being an ESO, also has a global perspective and, moreover, does consider reality. Secondly, having produced arguments a) to g), CEN/CENELEC has the audacity to call a meeting on Friday 25 February entitled "ICT standardization - improving collaboration in Europe". This sounds very nice, but they have not set the stage for constructive debate. Rather, they demonstrate a striking lack of vision and lack of perspective. I will back this up by three facts, and leave it there. 1. Since the 1980s, global industry fora and consortia, such as IETF, W3C and OASIS have emerged as world-leading ICT standards development organizations with excellent procedures for openness and transparency in all phases of standards development, ex post and ex ante. - Practically no ICT system can be built without using fora and consortia standards (FCS). - Without using FCS, neither the Internet, upon which the EU economy depends, nor EU institutions would operate. - FCS are of high relevance for achieving and promoting interoperability and driving innovation. 2. FCS are complementary to the formally recognized standards organizations including the ESOs. - No work will be taken away from the ESOs should the EU recognize certain FCS. - Each FCS would be evaluated on its merit and on the openness of the process that produced it. ESOs would, with other stakeholders, have a say. - ESOs could potentially educate and assist European stakeholders to engage more actively and constructively with FCS. - ETSI, also an ESO, seems to clearly recognize these facts. 3. Europe and its Member States have a strong voice in several of the most relevant global industry fora and consortia. - W3C: W3C was founded in 1994 by an Englishman, Sir Tim Berners-Lee, in collaboration with CERN, the European research lab. In April 1995, INRIA (Institut National de Recherche en Informatique et Automatique) in France became the first European W3C host and in 2003, ERCIM (European Research Consortium in Informatics and Mathematics), also based in France, took over the role of European W3C host from INRIA. Today, W3C has 326 Members, 40% of which are European. Government participation is also strong, and it could be increased - a development that is very much desired by W3C. Current members of the W3C Advisory Board includes Ora Lassila (Nokia) and Charles McCathie Nevile (Opera). Nokia is Finnish company, Opera is a Norwegian company. SAP's Claus von Riegen is an alumni of the same Advisory Board. - OASIS: its membership - 30% of which is European - represents the marketplace, reflecting a balance of providers, user companies, government agencies, and non-profit organizations. In particular, about 15% of OASIS members are governments or universities. Frederick Hirsch from Nokia, Claus von Riegen from SAP AG and Charles-H. Schulz from Ars Aperta are on the Board of Directors. Nokia is a Finnish company, SAP is a German company and Ars Aperta is a French company. The Chairman of the Board is Peter Brown, who is an Independent Consultant, an Austrian citizen AND an official of the European Parliament currently on long-term leave. - IETF: The oversight of its activities is by the Internet Architecture Board (IAB), since 2007 chaired by Olaf Kolkman, a Dutch national who lives in Uithoorn, NL. Kolkman is director of NLnet Labs, a foundation chartered to develop open source software and open source standards for the Internet. Other IAB members include Marcelo Bagnulo whose affiliation is the University Carlos III of Madrid, Spain as well as Hannes Tschofenig from Nokia Siemens Networks. Nokia is a Finnish company. Siemens is a German company. Nokia Siemens is a European joint venture. - Member States: At least 17 European Member States have developed Interoperability Frameworks that include FCS, according to the EU-funded National Interoperability Framework Observatory (see list and NIFO web site on IDABC). This also means they actively procure solutions using FCS, reference FCS in their policies and even in laws. Member State reps are free to engage in FCS, and many do. It would be nice if the EU adjusted to this reality. - A huge number of European nationals work in the global IT industry, on European soil or elsewhere, whether in EU registered companies or not. CEN/CENELEC lacks perspective and has engaged in an effort to twist facts that is quite striking from a publicly funded organization. I wish them all possible success with Friday's meeting but I fear all of the most important stakeholders will not be at the table. Not because they do not wish to collaborate, but because they just have been insulted. If they do show up, it would be a gracious move, almost beyond comprehension. While I do not expect CEN/CENELEC to line up perfectly in favor of fora and consortia, I think it would be to their benefit to stick to more palatable observations. Actually, I would suggest an apology, straightening out the facts. This works among friends and it works in an organizational context. Then, we can all move on. Standardization is important. Too important to ignore. Too important to distort. The European economy depends on it. We need CEN/CENELEC. It is an important organization. But CEN/CENELEC needs fora and consortia, too.

  • Creating PDF Documents with ASP.NET and iTextSharp

    The Portable Document Format (PDF) is a popular file format for documents. Due to their ubiquity and layout capabilities, it's not uncommon for a websites to use PDF technology. For example, an eCommerce store may offer a "printable receipt" option that, when selected, displays a PDF file within the browser. Last week's article, Filling in PDF Forms with ASP.NET and iTextSharp, looked at how to work with a special kind of PDF document, namely one that has one or more fields defined. A PDF document can contain various types of user interface elements, which are referred to as fields. For instance, there is a text field, a checkbox field, a combobox field, and more. Typically, the person viewing the PDF on her computer interacts with the document's fields; however, it is possible to enumerate and fill a PDF's fields programmatically, as we saw in last week's article. This article continues our investigation into iTextSharp, a .NET open source library for PDF generation, showing how to use iTextSharp to create PDF documents from scratch. We start with an example of how to programmatically define and piece together paragraphs, tables, and images into a single PDF file. Following that, we explore how to use iTextSharp's built-in capabilities to convert HTML into PDF. Read on to learn more! Read More >

  • White Paper on Analysis Services Tabular Large-scale Solution #ssas #tabular

    - by Marco Russo (SQLBI)
    Since the first beta of Analysis Services 2012, I worked with many companies designing and implementing solutions based on Analysis Services Tabular. I am glad that Microsoft published a white paper about a case-study using one of these scenarios: An Analysis Services Case Study: Using Tabular Models in a Large-scale Commercial Solution. Alberto Ferrari is the author of the white paper and many people contributed to it. The final result is a very technical document based on a case study, which provides a level of detail that I don’t see often in other case studies (which are usually more marketing-oriented). This white paper has the following structure: Requirements (data model, capacity planning, client tool) Options considered (SQL Server Columnstore Indexes, SSAS Multidimensional, SSAS Tabular) Data Model optimizations (memory compression, query performance, scalability) Partitioning and Processing strategy for near real-time latency Hardware selection (NUMA analysis, Azure VM tests) Scalability tests (estimation of maximum users per node) If you are in charge of evaluating Tabular as analytical engine, or if you have to design your solution based on Tabular, this white paper is a must read. But if you just want to increase your knowledge of Analysis Services, you will find a lot of useful technical information. That said, my favorite quote of the document is the following one, funny but true: […] After several trials, the clear winner was a video gaming machine that one guy on the team used at home. That computer outperformed any available server, running twice as fast as the server-class machines we had in house. At that point, it was clear that the criteria for choosing the server would have to be expanded a bit, simply because it would have been impossible to convince the boss to build a cluster of gaming machines and trust it to serve our customers.  But, honestly, if a business has the flexibility to buy gaming machines (assuming the machines can handle capacity) – do this. Owen Graupman, inContact I want to write a longer discussion about how companies are adopting Tabular in scenarios where it is the hidden engine of a more complex solution (and not the classical “BI system”), because it is more frequent than you might expect (and has several advantages over many alternative approaches).

  • Lotus Notes wants to open some emails with web browser, rather than within Notes itself

    - by John K.
    I have a problem with Lotus notes 8.5.1 wanting to open certain emails in my web browser, rather than within Notes itself. The emails that do this, seem to have some html in the note (Not just a link, but the note itself) This is a recent upgrade from 8.0.2 which had a similar problem, but it showed all of the html formatting characters in the notes, rendering it almost unreadable. I was hoping a fresh install of Notes would fix it, but it did not. I am using the same version of Notes & Win XP at work, and I do not have the problem. I am guessing that it is a setting on my home computer and not Notes, but I have no idea what it would be.

It is the foundation stone on which all other products (Exchange, update services, office communicator, the system center family, etc) rely on to get their information. And that is just looking at it from an infrastructure perspective. A well designed and implemented Active Directory implementation makes life for IT personnel and user alike a lot easier. Centralised management and the abilities opened up  by having it in place are ample.  But what is Active Directory Domain Services? We can look at ADDS as a centralised directory containing all objects your infrastructure runs on in one way or another. Since it is a Microsoft product you'll obviously not be seeing linux or mac clients listed in here (exceptions exist) but in general we can say it contains everything your company has in place in one form or another.  The domain name services. The domain naming service (or DNS for short) is a service which translates IP address (the identifiers for each computer in your domain) into readable and easy to understand names. This service is a prequisite for ADDA to work and having wrong record in a DNS server will make any ADDS service fail. Generally speaking a DNS service will be run on the same server as the ADDS service but it is worth wile to remember that this is not necessary. You could, for example, run your DNS services on a linux box (which would need special preparing to host an ADDS integrated DNS zone) and run the ADDS service of another box… Where to start? If the aim is to put in place a first time implementation of ADDS in your enterprise there are plenty of things to consider depending on what you are going to do in the long run. Great care has to be taken when first designing and implementing as having it set up wrong will cause a headache down the line. It is for that reason that I like to start building from the bottom up and start with a generic installation of ADDS (which will still differ for every client) and make it adaptable for future services which can hook in to the existing environment. Adapting existing environments is out of scope for this document (and series) although it is possible to take the pointers and change your existing environment to run in a smoother manor. Take great care when changing things as one small slip of the hand can give you a forest wide failure… Whenever starting with an ADDS deployment I ask the client the following questions:  What are your long term plans and goals?  How flexible do you want it? Are you currently linux heavy and want to keep this or can we go for an all Microsoft design? Those three questions should give some sort of indicator what direction can be taken and if the client has thought about some things themselves :).  The technical side of things  What is next to consider is what kind of infrastructure is already in place. For these series I'll keep it simple and introduce some general concepts without going in to depth on integrating ADDS with other DNS services.  Building from the ground up means we need to consider our layers on which our infrastructure will rely. In my view that goes as follows:  Network (WAN/LAN links and physical sites DNS Namespacing All in one domain or split up in different domains/forests? Security (both for ADDS and physical sites) The network side of things  Looking at how the network is currently set up can potentially teach us a large deal about the client. Do they have multiple physical site? What network speeds exist between these sites, etc… Depending on this information we will design our site links (which controls replication) in future stages. DNS Namespacing Maybe the single most intresting thing to know is what the domain will be named (ADDS will need a DNS domain with the same name) and where this will be hosted. Note that active directory can be set up with a singe name (aka contoso instead of contoso.com) but it is highly recommended to never do this. If you do end up with a domain like that for some reason there will be a lot of services that are going to give you good grief in the future (exchange being one of them). So one of the best practises would be always to use a double name (contoso.com or contoso.lan for example). Internal namespace A single namespace is just what it sounds like. You have a DNS domain which is different internally from what the client has as an external namespace. f.e. contoso.com as an external name (out on the internet) and contoso.lan on the internal network. his setup is has its advantages in that you have more obscurity from the internet in the DNS side of this but it will require additional work to publish services to the web. External namespace Quite like the internal namespace only here you do not differ the internal namespace of the company from what is known on the internet. In this implementation you would host your own DNS servers for the external domain inside the network. Or in other words, any external computer doing a DNS lookup would contact your internal DNS server for the resolution. Generally speaking this set up is a bad idea from the security side of things. Split DNS Whilst using an external namespace design is fairly easy it involves a lot of security risks. Opening up you ADDS DSN servers for lookups exposes your entire network to the internet and should be avoided at any cost. And that is where the "split DNS" design comes in. In this setup up would still have the same namespace internally and externally but you would be using different DNS servers for lookups on the external network who have no records of your internal resources unless you explicitly publish them. All in one or not? In determining your active directory design you can look at the following possibilities:  Single forest, Single domain Single forest, multiple domains Multiple forests, multiple domains I've listed the possibilities for design in increasing order of administrative magnitude. Microsoft recommends trying to use a single forest, single domain in as much situations as possible. It is, however, always possible that you require your services to be seperated from your users in a resource forest with trusts set up between the different forests. To start out I would go with the single forest design to avoid complexity unless there are strict requirements to have multiple forests. Security What kind of security is required on the domain and does this reflect the physical security on the sites? Not every client can afford to have a domain controller in a secluded server room on every site and it is exactly for that reason that Microsoft introduced the RODC (read only domain controller). A RODC is a domain controller that has been limited in functionality, in essence it will only cache the data you explicitly tell it to cache and in the case of a DC compromise (it being stolen) only a limited number of accounts will need to be affected. Th- Th- Th- That’s all folks! Well at least for now! In future editions of this series we’ll be walking through the different task that need to be done and the thought which needs to be put in to it. But for all editions we’ll be going from the concept of running a single forest, single domain with a split DNS setup… See you next time!

  • Apache port forwarding with ZTE ZXV10 W300 router (provider specific firmware)

    - by dannote
    I'm trying to configure port forwarding for Apache 2.2 installed on Windows XP SP3 with ZTE ZXV10 W300 router. The computer has a static IP 192.168.1.2. Port forwarding is configured as following: Enable true Name Apache Protocol TCP (also tried TCP and UPD) WAN Host Start IP Address empty WAN Host End IP Address empty WAN Connection stream WAN Start Port 8080 WAN End Port 8080 LAN Host IP Address 192.168.1.2 LAN Host Start Port 8080 LAN Host End Port 8080 Port 8080 is open for both TCP and UPD in Windows Brandmauer. Apache configuration: Listen 192.168.1.2:8080 Router Firmware: Hardware Version V1.0.01 Software Version V8.0.02T03_CFA Boot Loader Version V1.1.2 The provider is COMSTAR. I'm not sure but it's said they flash routers with modified firmware. I have also tried to set up Bitcomet port forwarding on port 13514 and failed.
