• Why would http & https be blocked, even in safe mode with firewall disabled?

  - by Cogwheel

  I have a windows 7 machine (dell studio xps). Everything on it seems to be in working order. The network device says it has internet connectivity, and indeed I can ping websites, transfer files via ftp, connect to vpns and remote desktop, but the web won't work. I've disabled the windows firewall and still no go. There are no other firewalls installed. The computer came with a trial of norton 360 so I also used the norton removal tool (which solved a similar problem on another computer for me previously). Any thoughts?

• Is there a specific name for the ".\" (dot-slash) shorthand used to log onto a Windows machine?

  - by HopelessN00b

  I guess the title just about says it all. And yes, .\, not that obsolete \. thing. :) For those who don't know, .\ is a shorthand way of saying "this computer" in Windows at a logon screen, which comes in very handy when you don't know or care about the local computer name but need to authenticate against it anyway, such as through RDP or scripting against a set of shared local users and passwords or even locally, if you're unlucky enough to have to physically go to a machine. Anyway, does this have an actual name, and if so, what is it? I feel kind of stupid saying the dot-slash thing, which is how I've been referring to this.

• What happens when you add a Graphics card to a i7 with build in graphics (e.g. HD 4000)

  - by Matt

  I'm thinking of upgrading my computer from an AMD Phenom II X4 955BE with a AMD Radeon HD 6800 Graphics card (not integrated) to using a Intel Core i7 3770. As I have no knowledge of integrated graphics, my question is, what happens to the computing power when not using the HD4000 integrated graphics of the CPU (does it mean the CPU will run faster then it would if I relied on it?) Also what is better the CPUs inbuilt HD4000 or my Radeon Graphics card? I am mostly interested in terms of content creation: Using Adobe After Effects, 3D Rendering etc. Not too bothered about gaming performance. I will be using the spare parts of this build and older systems to make a second computer for network renders so what will be the advantages of keeping the Radeon with the current system for that?

• DIY Halloween Decoration Uses Simple Silohuettes

  - by Jason Fitzpatrick

  While many of the Halloween decorating tricks we’ve shared over the years involve lots of wire, LEDs, and electronic guts, this one is thoroughly analog (and easy to put together). A simple set of silhouettes can cheaply and quickly transform the front of your house. Courtesy of Matt over at GeekDad, the transformation is easy to pull off. He explains: It’s really just about as simple as you could hope for. The materials needed are: black posterboard or black-painted cardboard; colored cellophane or tissue paper; and tape. The only tools needed are: measuring tape; some sort of drawing implement — chalk works really well; and scissors and/or X-Acto knife. And while you need some drawing talent, the scale is big enough and the need for precision little enough that you don’t need that much. For a more thorough rundown of the steps hit up the link below or hit up Google Images to find some monster silhouette inspiration.

• XP can't read data from transferred HD

  - by Alexander Miller

  Computer A, running XP, died. XP was installed on a fresh HD in computer B. Slaved data-backup HD from A was installed as slave on B. B will not read it; shows only 2 folders, Recycler and System Volume Info. All of these are older machines with IDE drives. What's going on & how can I read/transfer the data from the transferred drive? This was only a trial run. Actually I will need to transfer the master HD from A - which has XP on it - and read from its data partition because (blush) the backup drive was not up to date.

• how to restore grub

  - by takeshin

  During copying files via lan my Ubuntu Server 10.04 hung up and I had to reset the computer. After reboot, I got: Grub error 17, so I tried the rescue alternate CD, but I got a info, that no partitions were found on the disk. I used testdisk to restore the partitions. Using fdisk -l shows the partitions now, but when the system boots up I does nothing but displays: L234: When I plug the drive to another computer, it is not automatically mounted and I can't access the data. What to do now? How to restore the grub and boot up the system?

• Graphics Card Compatability

  - by Aaron

  I am a first time builder and while I have the basic understanding of how to put a computer together, one final thing eludes me. What are the requirements for instaling 2 or more graphics cards on a computer? Example: EVGA 015-P3-1589-AR GeForce GTX 580 (Fermi) FTW Hydro Copper 2 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card ECS NGTX580-1536PI-F GeForce GTX 580 (Fermi) 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card I am not planning on buying either of these cards in the near future. I simply am using them as an example because of the number of differences. As I understand it these two cards will work together (given the proper motherboard) because the only thing that matters is that they are both GeForce GTX 580. Is my assumption correct? If not, why?

• How to debug lack of sound in Asus EEE PC

  - by Kalmar

  I have an Asus EEE PC 1225B with fresh Lubuntu 12.04. And no sound. It doesn't seem to be some common problem, so I have to make some research what's up. I tried running alsamixer, so I know I have Realtek ALC269VB with nothing muted unexpectedly. What can I do next to identify and solve the problem? Additional info: alsamixer shows two cards: HD-Audio Generic and HDA ATI-SB (Realtek ALC269VB); the first one is muted. ~$ aplay ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave aplay: main:682: blad otwierania audio: Nie ma takiego pliku ani katalogu The Polish part can be translated as "error opening audio: There is no such file or directory". ~$ sudo lspci -v | grep -A7 -i "audio" 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] Subsystem: ASUSTeK Computer Inc.

• ERP/CRM Systems. Desktop Based ? Web based? [closed]

  - by Parhs

  I have seen 2-3 ERPs in action. I am wondering what is better. Desktop based application or webbased displayed on a browser. My first experience was with a web based ERP when i was 14 years old.. It was web based and terribly slow... For most simple task you had to do lots of clicks... no keyboard support ..... Pages took ages to load. Last year I worked for migrating to a newer computer some old terminal based cobol application. The computer that worked till today and still has no problem was from 1993. The user interface ofcourse was textbased.. The speed that guys placed orders was amazing! just typing the name of the customer , then 5-10 keys to add a product to order.... Comparing to this ERP the page for placing orders Link (click sales orders) seems terribly slow to add a product... No keyboard shortcut works to save what you added and generally I believe you need 4 times more time to place an order compared to the text interface... Having to use both mouse and keyboard for this task is BAD and sadistic... So how can the heck these people ever use a system like that ??? So in the long run desktop application seems the only way... Of course browsers support shortcuts but the way to overide the defaults that browsers uses isn't cross compatible... That is a huge problem. Finnaly, if we MUST/forced use cloud in near future what about keyboard shortcuts?? I feel confused... I have seen converters of desktop applications to browser applications but are SLOW as hell... The question is what about user friendliness? What kind of application would you use?

• Radiation from a UPS

  - by Erel Segal

  In our office, there are frequent eletric shortages that harm my desktop computer, so I wanted to install a UPS. However, my office-mates pointed me to papers talking about hazardous radiation from the UPS. The UPS manufacturers themselves recommend to put the UPS several meters away from humans, which is not possible because our office is small (the power is about 0.5 meters from us). As an alternative to UPS, my office-mates recommended that I switch to a laptop, which has a battery so it's immune to shortages. I have several questions: Is it true that the radiation from a laptop battery is lower than the radiation from a UPS? They do just the same thing - supply power using a battery! If the answer to 1 is yes - is there an alternative way to attach a battery, similar to a laptop battery, to a desktop computer? If the answer to 1 is no - how can I prove this to my office-mates, so that they let me use UPS?

• Using 4 monitors with 2 generic video cards... possible?

  - by Ikram

  I'm thinking of setting up 4 monitors in a grid, using two video cards, one card to feed each pair of monitors through the card's two DVI ports. The most important requirement for me is to have the grid of monitors act as one single huge screen. Is this scenario possible by using two generic cards like Radeon 4870s on a Windows 7 computer? (I've heard of Eyefinity, but 4870s don't have it) Another issue is that I only have one PCI-Express slot on my computer's motherboard, therefore I'll need to use one of the lesser PCI cards as the second video card. Will this pose problems?

• Windows 7 wifi reports "no network access" and "no internet access" but connects in fedora

  - by rick2047

  I am running windows 7 home basic (64bit) on a Acer 5742G laptop with Atheos wifi adapter in it. Yesterday, I hiberneted my computer as I always do and up untill then the wifi was working fine. When I booted my computer up again today I started having a strange problem: It detects my wifi but after connecting to it, it keeps on oscillating between states of no network access and no internet access. I can't connect to anything (the internet or my router). I tried to reset my internet protocol stack using this fixit file. I also tried to uninstall and reinstall my network driver. Neither helped. I am using the same laptop's fedora installation right now and the wifi is working perfectly fine. Please help. Edit To add additional details, I have Microsoft Security essentials as my antivirus software and I haven't messed with the firewall or the router configurations.

• What You Said: How You Share Your Photos

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite tips, tricks, and tools for sharing photos with friends and family. Now we’re back to highlight the ways HTG readers share their pics. Image available as wallpaper here. By far the most popular method of photo sharing was to upload the pictures to cloud-based storage. Many readers took advantage of sizable SkyDrive accounts. Dragonbite writes: I used to use PicasaWeb (uploaded from Shotwell) until I got the SkyDrive w/25 GB available. My imported pictures are automatically synchronized with SkyDrive and I then send out a link to whomever I want. I have another (desktop) computer where all of the pictures are stored from mine and my wife’s camera’s imports so if I need to free up some space on SkyDrive or my Windows 7 laptop, I double-check they are in the desktop computer before deleting them from my laptop (and thus from SkyDrive as well). I wish SkyDrive enabled some features like rotate, or searching by Tagged person. 8 Deadly Commands You Should Never Run on Linux 14 Special Google Searches That Show Instant Answers How To Create a Customized Windows 7 Installation Disc With Integrated Updates

• Connect to CentOS LAMP instance from Windows PCs

  - by Gnanesh

  I have a CentOS 6 machine running on our network which has a simple LAMP installation on it. I have some files there which I would want to access through other Windows PC which I am able to do so using the IP address of the CentOS machine. Since the IP address of the CentOS machine also could be dynamic I would want to connect to it using the computer / host name But I am not able to do so using the computer / host name of the CentOS machine. Can someone help me point out what I may be missing and help me out to resolve this?

• identifying windows service

  - by András

  On my win7 machine when I watch a movie in XBMC, once per hour the desktop regains the focus. The movie keeps playing, but in the background now, so I can only hear it. It is quite irritating. I noticed, that the Windows Application log always contains two entres for this time: "The description for Event ID 0 from source Self-service Plug-in cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer." One entry is for starting, and one for stopping 60 seconds later. This keeps repeating, every two starts 3600 seconds apart. How can I repair it? How can I find out which service it is?

• Windows XP Blue-Screens And Reboots Instantly On Boot-Up

  - by ashes999

  My computer was running perfectly until yesterday; my internet suddenly died. Being wireless, I decided to reboot; now the computer doesn't boot. It shows the "Starting Windows" screen (safe mode loads several drivers), then it suddenly blue-screens and immediately reboots (I cannot read the blue-screen contents at all). I've tried safe-mode (with and without networking); no dice. I booted another HD with another XP install and ran scandisk on my HDs; no bad sectors, and even with auto-repair, it didn't fix the problem. Now what? What are my options to fix the broken XP install? I'm thinking: 1) Remove wireless card 2) Run XP install CD and repair installation 3) ???

• Can't mount home after trying to resize (bad geometry: block count exceeds size of device).

  - by Lynn

  This is on a fresh computer (super computer actually). It got to me with 15T on the home mount and 50G on the root. I tried allocating 7T to root and resizing (since I'm putting a local yum repo on this machine as it has no internet access nor will it ever). I tried following the instructions here: Centos 6.3 disk space allocation but something went wrong and the home won't mount again. Instead I get from dmesg | tail: EXT4-fs (dm-2): bad geometry: block count 4294967295 exceeds size of device (1342177280 blocks) df -h nets this output: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 7.0T 3.6G 6.6T 1% / tmpfs 190G 216K 190G 1% /dev/shm /dev/sda1 485M 38M 422M 9% /boot I didn't have any files on /dev/mapper/VolGroup-lv_home. Will simply running mke2fs fix it to be mountable? What sort of options should I run it with. I've never resized volumes before or used mke2fs. I don't want to make this mess worse.

• What kind of eye wear can I use to protect my eyes from being irritated from staring at a screen all

  - by dr dork

  Many of us stare at computer screens all day. Lately, my eyes have been irritated from prolonged staring at my computer screens. Does anyone use or know of any eye wear technology that helps with this? About five years back, I bought a pair of non-prescription eye glasses that had a no-glare layer put on them by an optometrist. It slightly helped, so I'm considering getting another pair. Is this the best option I have at this point? Thanks so much in advance for your wisdom!

• Avoid cache overflow in Atempo LiveBackup

  - by Vebjorn Ljosa

  When attempting the initial backup of a new client, Atempo LiveBackup seems to require a very large cache. For instance, a 20 GB cache is not enough to back up a computer that has 100 GB of data. It appears that LiveBackup is adding new files to the cache at a faster rate than it can send them to the server. When the cache fills up, the backup fails. Aside from removing most data from the computer and then add them back gradually after the initial backup, is there a good workaround? Is it possible to make LiveBackup slow down its scan so as to not fill the cache? Or is it possible to place the cache on an external drive?

• How to configure DD-WRT routing table when creating an isolated network segment for PCI C VT compliance

  - by tetranz

  I'm the volunteer support and system admin person at a small private school. We need to setup a PCI compliant Windows PC as a virtual terminal for credit card processing. I've read questionnaire SAQ C-VT and, to quote, this computer needs to be accessed: "via a computer that is isolated in a single location, and is not connected to other locations or systems within your environment (this can be achieved via a firewall or network segmentation to isolate the computer from other systems)" Our setup is as follows: DSL modem from ISP is setup to be a "transparent pipe" with no extra services. That goes into the WAN port of Linksys WRT54-GL running a DD-WRT. The LAN is 192.168.1.x. There are a couple of other WRT54-GL / DD-WRT devices. One is used as a wireless AP and another is a client bridge. To isolate the VT (virtual terminal) machine, I have another DD-WRT device. Its WAN is connected to a port on the 192.168.1.x LAN. The virtual terminal machine is connected to its LAN which is at 192.168.10.x. The SPI Firewall etc is turned on. It's basically the default DD-WRT gateway setup where the "ISP" is our own LAN. That's working. All incoming traffic to the VT machine is blocked, including from our own LAN. The VT can access the internet BUT, and here's the problem, it can also ping any of the computers on the 192.168.1.x LAN. I think I need to stop that. I'm guessing that I could do something with the Static Routing table in the VT machine's DD-WRT device. I need to route anything going to 192.168.1.x other than the gateway which is 192.168.1.1 to 0.0.0.0 or something like that. That's where I'm stuck at the end of my knowledge. Or ... do I need to get yet another DD-WRT so the network is "balanced". Maybe I need to have the internet from the DSL going into a DD-WRT which has only two devices on its LAN i.e., two other DD-WRTs, one for the main LAN and one for the VT. I think that would do but I'd like to avoid the extra cost and complexity if I don't need it. Thanks

• Remote desktop to multiple windows machines on a LAN with dynamic IP

  - by kevyn

  Is it possible to use remote desktop to connect to multiple computers inside a network that has a dynamic IP address? I use a netgear WPN824 router which has dyndns onboard - but I currently use No-IP to control a single computer that I use most frequently. Every so often I need to get onto a couple of other computers in the network, but don't know how to go about this without logging onto one computer, and then starting another RDC session from that machine. What I would like to be able to do is connect to my router, and be able to see a list of connected devices, and then choose which to remote desktop onto. - I appreciate this probably is not be possible, but any other suggestions are welcome!

• Is Windows Server 2003 on 96 MB possible?

  - by Nifle

  I have an old laptop, a Pentium II with 96 MB. I have had Windows 2000 on it for ages, it was slow but usable. But now I have to upgrade since I can't get my USB-wlan drivers to install (the old PCMCIA network card broke). I would prefer to install Windows XP but I have no spare licence, but I do have a Windows Server 2003 licence. Do you think it's possible (and usable) to squeeze in 2003 on this computer? Edit: Unfortunately 2003 simply refuses to install on the laptop. It hangs with an error message (paraphrased) 2003 has detected a problem with your computer and has halted the installation to prevent damage. And then some error codes This happens very early in the installation while it's copying the installation files just after I accepted the licence. So I give up for now.
