  • Cannot activate windows 7

    - by Charlie
    I can't activate Windows 7, I get an error saying DNS name does not exist. Is something configured incorrectly somewhere? PS: I need the answer within 13 days ;) UPDATE: I had upgraded from my company's Windows Vista build, and when I connect to the company VPN and activate I get a different error: The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information. The Application Event Log contains this (I took out the server name, it's one of the company servers): The client has sent an activation request to the key management service machine. Info: 0xC004F042, 0x00000000, xxxxxxxxxxxxxxxxxxxxxxxxx.com:1688, 7fbdc9b7-d654-49ed-80a7-81a34408f8dc, 2009/09/01 10:59, 0, 2, 17880, ae2ee509-1b34-41c0-acb7-6d4650168915, 25

  • Internet not working on a VirtualBox Linux machine

    - by mtahmed
    I installed VirtualBox on a Windows 7 PC and installed Xubuntu (Ubuntu with XFCE) on it. Now on the Windows, I am connected to the internet through a LAN which automatically authenticates to connect to the network(because its my work computer). I have also installed the guest additions on this virtual machine (Xubuntu). I tried both NAT and bridging to set up internet connection but I still cannot connect to the internet. For NAT: The browser doesn't say website not found but it keeps trying to load it forever and the network status monitor (the one provided by VirtualBox) doesn't show any green light (no incoming packets). For Bridging: Same as for NAT but the network status monitor shows incoming packets and outgoing packets. But internet still doesn't work. I tried a lot of different things but none worked.

  • How to start Windows Explorer as domain administrator [closed]

    - by Otiel
    Possible Duplicate: How do you run windows explorer as a different user? Is it possible to start a Windows Explorer with the rights of another domain user? I tried to do the following to start a Windows Explorer on my computer as my domain Administrator, but without success: Right click on C:\Windows\explorer.exe to select Run as different user, Enter the domain administrator credentials: Domain\Administrator ************ The windows explorer session only opens with my current user rights (Domain\me). The reason behind my question is that I want to change some folder rights on a domain shared disk and I need the Domain\Administrator user rights to do it. Usually, I do it by login as Domain\Administrator on the server hosting the shared disk but I would like to be able to do it from my PC, logged as my current login (Domain\me). EDIT As seen in the linked posts, it is not possible anymore on Windows Vista or 7. On Windows XP, the solution is to do: runas /user:domain\username "explorer /separate"

  • Sendmail is refusing connection after configuring SMTP relay

    - by coder
    I'm setting up sendmail on my home computer to use with my webserver. I've set it to use my SMTP server provided by my hosting company. If I use the following command, it works sendmail -Am -t -v and then I enter the to and from emails. But if I try the following, it does not work. sendmail -v [email protected] < test.txt The TO email is the same as in the earlier command, but in this case I haven't specified a FROM e-mail, which I think is the problem. My guess is that it's sending the mail from user@localhost causing the smtp server to reject it. If so, how do I make it send from [email protected]?

  • Use all 5.1 speakers with a 2.1 audio source

    - by thegreyspot
    Hi! I just bought a 5.1 surround sound speaker set for my computer in my bedroom. The rear speakers are next to me in bed while the front speakers are at the other end of the bed at my feet. While I enjoy the surround sound during movies that support 5.1 sound, I would like to have my rear speakers working when listening to podcasts, or other 2.1 channel sound. How can I do this? When I enable "Speaker Fill" in the Realtek Hd Audio manager the sound only comes out of the front and center speakers with a few background noises that come out the rear ones. But since my ears are closer to the rear speakers, I'd rather have the sound come out of them. Let me know of any ideas! Hmm seems like the only option is to set the rear speakers to "Front Speakers" and change it to stereo in the Realtek HD audio. But still that take alot of steps and it doesnt not use the center speaker Thanks

  • Tool to fix video that's out of sync with audio?

    - by Javier Badia
    I'm looking for (preferably free) software for Windows 7 that will allow me to fix an AVI file that has audio out of sync with the video. I tried with Windows Live Movie Maker and VirtualDub and couldn't find out how to do it (if at all possible) on both of them. If any of those can help me, instructions for that would also be nice. Background: I have a RCA-to-USB capture card, which I'm using to transfer VHS casettes and stuff from a video camera to digital format. The problem is that the audio comes out heavily distorted. So instead I connected the audio out from the VCR directly to the computer's line in. This works, but the audio is out of sync, about half a second behind the video. I could spend time trying to fix this issuee, but I think it'll be easier to simply fix the video.

  • Can't find onboard NIC with windows server 2008

    - by Sanarothe
    Hi. I'm trying to setup a windows server, but I can't seem to get it to install ethernet drivers :( motherboard is ms-6743 chipset 82865g/pe/p(intel) The MSI drivers specifically for this motherboard are bad links. Not surprising... MSI is rarely helpful. Sisoft Sandra doesn't see any network devices, and all of my leads to drivers have reported that there is no network adapter to install a driver for. The light is ON on the mobo, the onboard setting in bios is ON and the computer worked just fine with a standard install of windows 7 about a month ago. I don't know what to do :(

  • Mutli-processor workstation as a workstation/server

    - by posdef
    I work in a research institute and a number of programs we use are computationally intensive (I actually wrote one of them). Right now we have one computer that is dedicated for one of these programs (with local accounts only, as in users physically sitting in front of that pc) and the other programs are run on individual workstations assigned to people. I have been looking around to common brands such as Dell and HP, for a some sort of a small/medium scale server, which can be used as a workhorse by sending tasks remotely. It appears as if there is nothing in between workstations with one 6-core processor and a bunch of extras (like fancy graphics etc) and rack mount servers with ridiculous amount of RAM and HDD expansion capabilities but still relatively little number of processors/cores. I wonder if what I am looking for is such a small niche product? Are there other solutions that I might not be aware of? Does anyone know of a multi proc- multi-core workstation/server that is still within the reasonable

  • Win7 to Win7 Remote Desktop Not working, Xp to 7 working fine

    - by vlad b.
    Hello, I have a small home network and recently i tried to enable remote desktop for one of the pc's. I have a mix of Windows 7, Windows Vista and Xp runing alongside ubuntu, centos and others (some virtual, some real). I have a few Windows 7 pc`s that can be connected to using remote desktop from inside and outside the network (port redirects on routers, etc, etc) and some Xp ones. The trouble is when i tried to do the same thing to a Win7 laptop i discovered i can't connect to it from another win7 pc inside the home network. To sum it up Working: xp -- win7 not working: win7 -- win7 What i tried - disable and enable remote desktop (my computer - remote settings) - removing and adding users to the remote settings window - adding a new user to the machine, administrator or 'normal' user - checking the firewall settings on the machine and set 'allow' to remote desktop for both 'home/work' and 'public'networks Any tips on what should i do next? It displays ' .. secure connection' and after that the window with 'Your security credentials did not work' and it lets me try again with another user/password..

    Andrejus Baranovskis: Oracle OpenWorld 2010 - Developing Large Oracle ADF 11g Applications Oracle ACE Director Andrejus Baranovskis shares a preview of the presentation he will give at Oracle OpenWorld 2010. (tags: oracle otn oracleace oow10) Andy Mulholland: Complicated or complex architecture or solutions "Enterprise architecture, and EAI middleware, is not likely to be the answer to this, instead we should be looking at provisioning through using the granularity of ‘services’ as opposed to the monolithic approach of applications. Actually it’s not one or the other, it’s both used together. The goal is to introduce an abstraction layer between the core processes represented by applications connected together through closed coupled middleware in defined relationship, and the loose coupled environment of services with the flexibility of orchestrations. At least in part the ability of drag and drop tools to produce orchestrations ‘on-demand’ starts the change towards user-driven views on ‘outcomes’ that suit them rather than the computer’s database."

  • NetApp erroring with: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT

    - by Sobrique
    Since a sitewide upgrade to Windows 7 on desktop, I've started having a problem with virus checking. Specifically - when doing a rename operation on a (filer hosted) CIFS share. The virus checker seems to be triggering a set of messages on the filer: [filerB: auth.trace.authenticateUser.loginTraceIP:info]: AUTH: Login attempt by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20 (server-wk8-r2). [filerB: auth.dc.trace.DCConnection.statusMsg:info]: AUTH: TraceDC- attempting authentication with domain controller \\MYDC. [filerB: auth.trace.authenticateUser.loginRejected:info]: AUTH: Login attempt by user rejected by the domain controller with error 0xc0000199: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT. [filerB: auth.trace.authenticateUser.loginTraceMsg:info]: AUTH: Delaying the response by 5 seconds due to continuous failed login attempts by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20. This seems to specifically trigger on a rename so what we think is going on is the virus checker is seeing a 'new' file, and trying to do an on-access scan. The virus checker - previously running as LocalSystem and thus sending null as it's authentication request is now looking rather like a DOS attack, and causing the filer to temporarily black list. This 5s lock out each 'access attempt' is a minor nuisance most of the time, and really quite significant for some operations - e.g. large file transfers, where every file takes 5s Having done some digging, this seems to be related to NLTM authentication: Symptoms Error message: System error 1808 has occurred. The account used is a computer account. Use your global user account or local user account to access this server. A packet trace of the failure will show the error as: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT (0xC0000199) Cause Microsoft has changed the functionality of how a Local System account identifies itself during NTLM authentication. This only impacts NTLM authentication. It does not impact Kerberos Authentication. Solution On the host, please set the following group policy entry and reboot the host. Network Security: Allow Local System to use computer identity for NTLM: Disabled Defining this group policy makes Windows Server 2008 R2 and Windows 7 function like Windows Server 2008 SP1. So we've now got a couple of workaround which aren't particularly nice - one is to change this security option. One is to disable virus checking, or otherwise exempt part of the infrastructure. And here's where I come to my request for assistance from ServerFault - what is the best way forwards? I lack Windows experience to be sure of what I'm seeing. I'm not entirely sure why NTLM is part of this picture in the first place - I thought we were using Kerberos authentication. I'm not sure how to start diagnosing or troubleshooting this. (We are going cross domain - workstation machine accounts are in a separate AD and DNS domain to my filer. Normal user authentication works fine however.) And failing that, can anyone suggest other lines of enquiry? I'd like to avoid a site wide security option change, or if I do go that way I'll need to be able to supply detailed reasoning. Likewise - disabling virus checking works as a short term workaround, and applying exclusions may help... but I'd rather not, and don't think that solves the underlying problem. EDIT: Filers in AD ldap have SPNs for: nfs/host.fully.qualified.domain nfs/host HOST/host.fully.qualified.domain HOST/host (Sorry, have to obfuscate those). Could it be that without a 'cifs/host.fully.qualified.domain' it's not going to work? (or some other SPN? ) Edit: As part of the searching I've been doing I've found: http://itwanderer.wordpress.com/2011/04/14/tread-lightly-kerberos-encryption-types/ Which suggests that several encryption types were disabled by default in Win7/2008R2. This might be pertinent, as we've definitely had a similar problem with Keberized NFSv4. There is a hidden option which may help some future Keberos users: options nfs.rpcsec.trace on (This hasn't given me anything yet though, so may just be NFS specific). Edit: Further digging has me tracking it back to cross domain authentication. It looks like my Windows 7 workstation (in one domain) is not getting Kerberos tickets for the other domain, in which my NetApp filer is CIFS joined. I've done this separately against a standalone server (Win2003 and Win2008) and didn't get Kerberos tickets for those either. Which means I think Kerberos might be broken, but I've no idea how to troubleshoot further. Edit: A further update: It looks like this may be down Kerberos tickets not being issued cross domain. This then triggers NTLM fallback, which then runs into this problem (since Windows 7). First port of call will be to investigate the Kerberos side of things, but in neither case do we have anything pointing at the Filer being the root cause. As such - as the storage engineer - it's out of my hands. However, if anyone can point me in the direction of troubleshooting Kerberos spanning two Windows AD domains (Kerberos Realms) then that would be appreciated. Options we're going to be considering for resolution: Amend policy option on all workstations via GPO (as above). Talking to AV vendor about the rename triggering scanning. Talking to AV vendor regarding running AV as service account. investigating Kerberos authentication (why it's not working, whether it should be).

  • How to contact an emergency service using only Internet?

    - by Vi.
    Suppose you are apart from the mobile or whatever phone (so can't call 112 or 911 or 999), but have have access to a computer with internet connection. How do you call/message an emergency service (of whatever country in hope they will route the request to the correct destination) using only Internet? Maybe there's some 911-like website or public SIP or whatever? Or better go to some chat/forum/StackExchange/whatever and ask somebody to make a call for you? (will users really believe?) /* 1. I'm not in any emergency, just curious. 2. I'm not sure on what SE site to ask this question. */

  • Which version of rails should I install with ruby 2.0.0 installed?

    - by Ekin Hazal
    Hi I am building a ROR development environment on a new computer with windows 7, now I have Ruby version 2.0.0 and Gems version 2.2.2 installed. Which version of Rails should I install? I saw this on rubyonrails.org/download : "We recommend Ruby 2.1.0 for use with Rails. We stopped supporting Ruby 1.8.x after Rails 3.2. Ruby 1.9.2+ will be supported until Rails 5." I will be working on a long-time project, I'm just trying to lessen the headaches I will have later. Right now, the latest Rails -v is 4.1.0 and they recommend Ruby 2.1.0 for use with Rails. I think the best option is to go with this set. Any other thoughts?

  • Update KB951847 (3.5 SP1 and Family Update) fails on Windows Server 2003 repeatedly

    - by Ducain
    We have a Win2K3 server that is perpetually stuck on the following update: Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update for .NET versions 2.0 through 3.5 (KB951847) x86 It fails every time, and I'm at a loss on what to do about it. WHAT I'VE TRIED: Saw an article that said to turn off the update service, rename C:\Windows\SoftareDistribution\ and then restart the update service. Did this, ran the update, and it failed on this same one. I tried to run the update manually at C:\Windows\SoftwareDistribution\Downloads\Install\ and again it fails. Says, "None of the products that are addressed by this software update are installed on this computer. Click Cancel to exit setup." Because of this issue, none of the previous updates will work either. I will give one large pink-glazed donut with sprinkles to anyone who can help me slay this beast.

  • Extreme Optimization Numerical Libraries for .NET – Part 1 of n

    - by JoshReuben
    While many of my colleagues are fascinated in constructing the ultimate ViewModel or ServiceBus, I feel that this kind of plumbing code is re-invented far too many times – at some point in the near future, it will be out of the box standard infra. How many times have you been to a customer site and built a different variation of the same kind of code frameworks? How many times can you abstract Prism or reliable and discoverable WCF communication? As the bar is raised for whats bundled with the framework and more tasks become declarative, automated and configurable, Information Systems will expose a higher level of abstraction, forcing software engineers to focus on more advanced computer science and algorithmic tasks. I've spent the better half of the past decade building skills in .NET and expanding my mathematical horizons by working through the Schaums guides. In this series I am going to examine how these skillsets come together in the implementation provided by ExtremeOptimization. Download the trial version here: http://www.extremeoptimization.com/downloads.aspx Overview The library implements a set of algorithms for: linear algebra, complex numbers, numerical integration and differentiation, solving equations, optimization, random numbers, regression, ANOVA, statistical distributions, hypothesis tests.

  • Getting into game/game engine programming

    - by Darkslash
    So I am interested in learning game programming, but I really have an interest in the lower level engineering in games. I have openGL experience, and I am really interested in learning more about implementing AI, Physics, etc. I have a computer science degree, so I really like getting into technical stuff. Many times when I ask about this sort of thing, I get a lot of "Use an engine", "Use Unity3d", "Why waste your time writing code that already exists", etc etc. My idea was to use simpler libraries such as SFML or XNA so that I could learn how to implement the more complex systems. The thing is, although I do want to write games, I want to learn things that using something like Unity simply doesnt teach you. My goal is not to make a current generation quality 3D game to sell, I just want to make some cool smaller games and learn all I can about the programming side of game development. Is this something that people just do not do anymore? It seems like everywhere I turn people are using Unity or UDK or GameMaker. I fully understand why you would use a tool like these, but I cant see how they would suit my purposes. So where does someone like myself turn? Am I trying to learn something that people just do not bother doing anymore? Is the innovation in this area gone and just all about gameplay now? Im sorry if this question seems silly, but I am genuinely interested in knowing more about this and meeting more people who are interested in this sort of thing.

  • setting visual bell to flash in iTerm

    - by blackwing
    Hi, I am using iTerm on OSX (leopard) to ssh to a linux machine. I run screen on the dev machine to save my work between sessions. I am not a big fan of audio bell and I don't like screen's default 'Wuff Wuff' bell (or any other little message shown at bottom of the page). What I like though is to have flash (foreground and blackground colors swapped for a fraction of a second) as my visual bell. I used to use PuTTY and it is as simple as ticking a checkbox but I can't find such an option in iTerm. My question is how can I set my visual bell to flash? The ideal answer would work with iTerm on local computer, iTerm sshed to a linux server, and iTerm sshed to a linux server and ran screen.

  • Hiding a file or data from being accessed unless on scheduled days [closed]

    - by gkt.pro
    Possible Duplicate: restricting access to volumes disk even for admin account windows How to restrict use of a computer? I want to limit my access to some data and what I want is that I should be able to access the data only on certain days of the month (e.g., every 3rd day). Is there any way like encryption or some utility to allow me to only access data on specific days? One idea that I was thinking of was to encrypt the data and store the password (will be complex and long so that I couldn't remember it right away) on some website which would then email me back the password in future on those specific days.

  • Is using Capistrano for user maintenance tasks on university lab feasible?

    - by danielkza
    I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

How can I know what temp3 is, and why it is so high? The system is really stable (which I guess it wouldn't be at those temps). Also, note the really decent core temps, which suggest a healthy system as well. My guess is that the readout is wrong. On another computer it reported temperatures below 0 degrees centigrade, which was not possible, considering the environment temperature of ~22-24. Is this some known bug/issue? Should I try some Windows programs (like CPU-Z) and see they give similar results?

  • Remove windows line endings (crlf) on basic windows 7 install?

    - by Marc K
    Is there a way to remove windows line endings on a basic windows 7 install. I'm working on a windows 7 computer with notepad and word 2010 at work. I'm trying to demo markdown without installing additional text editor, and keeping it installed locally. I've tried Word with replace on \r\n, special characters and other ways and it can't locate. Notepad same issue. Or is there a markdown converter that an online markdown converter that will handle windows line endings?
