• Sharing VPN access between two computers on the LAN

  - by Axelle Ziegler

  I have VPN access to several machines in my office from my home machine. I'd like to be able to access those machines from another computer on my LAN, without setuping a second VPN access. Both computers are Windows 7 machines. Is there a way for my "main" computer to share its VPN access to another machine on the LAN? How would one setup this share? I don't think "simple" Internet connection sharing fits my needs because: My LAN already has its own DHCP/Router to access the Internet, and I'd like to keep it this way I can't access the Internet through my VPN connection

• Config Time Service on Server 2008 DC using Group Policy Only

  - by Ed Fries

  I want to configure the Time Service using only GP in a Server 2008 R2 domain. I have created a GP as follows: Computer Config, Policies, Administrative Templates, System, Windows Time Policy: =Global Configuration Settings -Enabled w/ default settings. Computer Config, Policies, Administrative Templates, System, Windows Time Policy,Time Providers: =Configure Windows NTP Client -Enabled w/ default settings. =Enable Windows NTP Client -Enabled w/ default settings. =Enable Windows NTP Server -Enabled w/ default settings. The policy is linked, enforced and applied to Domain Controllers OU. The GP modeling results shows the policy is in effect on the DC (Single DC domain) and the DC is recognized as the PDC emulator. I have run gpupdate /force and logged off/on. The issue is that the DC shows the time source as internal. I understand I can force this at the cmd line using w32tm to set the peer but I would like to understand what is missing in the GP. The default NTP Client GP setting includes time.windows.com,0x9 as the source but it does not appear to be taking effect.

• PCs with Wired Connection Keep Losing Internet Connectivity

  - by user717452

  I have a U-verse ATT DSL Internet at our church building. Recently, any computer that is plugged into the network via Ethernet keeps losing its internet connectivity. The setup is from the Modem to a Netgear Wireless Router, and from the router to 3 different computers. None of the laptops that use Wifi ever lose internet, just the wired ones, and I end up having to do ipconfig /release and /renew every day to get it back. One computer has Windows 7 and one has Windows XP. Any ideas as to what is going on with our network?

• Cannot delete movie on iTunes for iPhone 4?

  - by Jian Lin

  I was on vacation and took some videos, and now the iPhone 4 memory is near full. So I tried to delete other experimental movies I made using Handbrake, so that I can take more video or photos, but if I plug the iPhone 4 into my Notebook computer, I can seem to delete it on iTunes? Maybe because the computer I sync with the iPhone 4 is at home (a desktop), but not with me on vacation. I can't delete it on iTunes, can't delete it on iPhone itself. I am stuck during the vacation, or is there a way to handle it?

• Need Directions to become a programmer [closed]

  - by Omin

  Before youguys go on about how there are many types of programmers, please read through the post. Long term goal: Develop my own software (company) Short term goal: Get a job that involves coding/programming Current status: Support Analyst (at a software company but does not involve any programming) with 40k salary, 3rd year computer engineering student I had everything figured out. I'm going to develop a 2D scrolling game for iphone or android, publish the app, sell a bunch, and then apply at a studios as a software developer. And then something hit me. I think I need to get a job that involes programming to learn as much as I can in the shortest time possible. So I got a phone interview at a fast growing start up software company, passed that no problem, but then had to take an online technical assessment. That failed miserably. I thought that if I could just present myself, show that I am hard working, positive attitude, eager to make self improvements, type of a guy, I could get the job. I was wrong. And now, I am lost. Im thinking of staying with my job until I find a new one as a programmer. I will be working, self studying, and trying to make this happen without finishing university. I forgot to mention that the online technical assessment was based on data structures/algorithms, OO design, runtime complexity. I was hoping that I could get some guidence. Should I be focusing on app development or study computer science fundamentals? I have a list of books I can be going through: Learning C# O'Reilly (I got interested in C# because of Unity3D and Mono), C# 5.0 in a Nutshell, Head First Design Patterns, Code Complete, Introduction to Algorithms, Programming Interviews Exposed, Cracking the Coding Interview, The Google Resume.

• arp across subnets which devices can be detected?

  - by Gobliins

  i have some devices connected in the same physical network (LAN) but in different subnets. I want to detect them all with the ARP from my computer. My Computer is also in the same physical network but on a different subnet. ! The devices have no arp protocol installed (yet). Is it possible to detect the devices (with or withour ARP installed on every device)? If the devices have a MAC-address but no IP-address, can ARP still detect the machines?

• Downclock CPU reaching critical temperature

  - by Draga

  I have an HP tx1250 laptop. It always had serious overheating problems and although usually it runs fine I'm now running a continuous test for my dissertation, this brings the CPU temp close to the critical and from time to time the computer shutdown for reaching it (checked the log). I use to have the same problem on Win XP but I noticed Win Vista and 7 downclock the CPU when is necessary to cool it down so I was thinking if the same is possible on Ubuntu 12. The only program I've found that may do the job is computer temp ( http://computertemp.berlios.de/ ) but it doesn't seems to work under Ubuntu 12. The inside of the laptop is fairly clean, the thermal paste is quite recent, I'm keeping it lifted from the desk and judjung by the sound of the fan that's running fine as well. The pc in now running between 78 and 91 degrees C but about once a day it shut down for reaching 95. I need the results of the test it's running pretty soon so it's important that it runs non-stop. I've though to set the maximum clock of the CPU to slightly less the maximum but then these tests I'm running would take much more time. Thanks! PS: first and last HP laptop for me.

• formating a hard drive for use in an asus aspire one d250

  - by paynes_bay

  I have an Asus Aspire One D250 that's out of warranty and whose hard drive is giving the click of death. I'm trying to use a spare SATA HDD I have but am having some difficulty. I have a USB CD drive that I plugged into the computer but when I tried to boot off of a Windows XP SP3 install CD the hard drive wasn't recognized. I tried to format the hard drive in another computer and then plug the hard drive into the Asus Aspire and although this gets me to the Windows XP loading screen it crashes before it gets into Windows, itself. Even in Safe Mode. I also tried to install Windows XP off of a USB stick but it seemed to hang during the install process. As in the next day it was still in the blue screen installer. Any ideas?

• How to fix Asus Eee PC 900 startup issues after failure?

  - by EBrown

  My Asus Eee PC 900 shows no signs of life. I push the power button and get no response from anything. No lights, no power, no boot-up screen. It has been like this since I received it from a friend. I asked her what happened and she said that smoke came from the keyboard, it shut down and hasnt turned on since. I have tried removing and cleaning the RAM, the computer charger still connects and works, but the battery receives no charge and the computer won't power on. Any ideas as to what is going on?

• Conflicts with MS Office temporary files when using Offline Folders on Vista

  - by Tambet

  We are using Offline Folders feature of Windows Vista to make files on network shares available when out of office. Mostly it is working, but every time I do a sync I get a lot of such errors: D500E7B8.tmp - A file was deleted on this computer and changed on the server while this computer was offline. There are hundreds of them. I always select all of them and choose resolution "Delete from both locations". But what is causing this and how can I avoid it? I suspect the reason is that we are using Debian and Samba (3.4.7) on our file server. I've been looking for some Samba options that would cure this, but with no success. I learned that probably the cause is, that both Word and Excel are using specific pattern to change files - they never change the original file, but instead always write a new temporary file and rename it to original file, when you click Save. This is documented here: http://support.microsoft.com/kb/211632/?FR=1.

• Can't connect to IIS7 on one of my machines

  I have 2 computers, both running Win7 Professional x64. Computer "A" (192.168.0.10) is my work machine, it contains my tools etc. Computer "B" (192.168.0.15) is supposed to be my build server / web server for my projects I've installed IIS on "B", and installed IIS7 remote manager on "A". I'm trying to connect from A's IIS7 Manager to B's IIS but I fail. I have little knowledge of IIS, and I feel that's the main reason. I can ping B from A and get positive results so the machines do see each other. A and B are in the same workgroup but not in a domain (if that matters) - they're in my home network. What do I need to do to "see" B's IIS?

• bottle.py on EC2 micro instance causes 2 order of magnitude slowdown

  - by user61633

  Cross-posted from StackOverflow: I wrote a little toy script to solve this type of game, and put it on my new micro EC2 instance. It works perfectly, but while it takes around 0.5 seconds to run a local version, and takes under 0.5 seconds to run both the local and the bottle.py version on my home computer, running the bottle.py version on the EC2 instance takes over 2 minutes. Python has the cpu pegged at 99% the entire time. Only 7.4% memory usage, consistently, and no swapping. The only guess I have is initialization time for bottle.py on EC2, but if it were that, why would it be ~200x faster on my own computer with bottle.py?

• Windows doesn't recognise my USB key anymore (it used to work)

  - by dominicbri7

  I use my friend's USB flash drive (Corsair flash voyager 16gb) to transfer files from my laptop to my desktop computer. However, since a couple of days my laptop stopped recognizing the USB key.. while there is still no problems with all other computers. I use Windows 7 64 bits if that can help. I tried uninstalling the driver, rebooting and all those kind of tricks, but it won't work. When I connect it and open the "My computer" window, I see "Removable Disk (G:)" for a moment, then it disappears... then it reappears again and it keeps doing that periodically. I can't even right click then hit "Properties" because it disappears. As I recall, it DOES work on every other computers, I think it has to do with the driver but what can I do?

• OS X: How to create a user account with access to the applications that she has installed only.

  - by pmurillo

  Till now, I've been the sole and proud owner of an iMac. I've always logged in as an administrator and I've also installed a bunch of software following the standard procedure of dragging and dropping it into the Applications folder. This is about to change, as sharing it with a friend makes a lot of sense now that I only have time to use the computer in the mornings, and she can only use it at nights. I thought this was going to be really easy: Just create a user account for her and that's all, I thought. Unfortunately, this is not the case. When she logins into the computer using her username and password, she has access to the same applications I've installed. Even the same applications that I setup to automatically start when I login start for her when she does. How can I setup a user that has only access to the applications that she has installed, but none of the ones installed by other users? Many thanks

• What would prevent a .BAT file from being run on a mapped drive?

  - by JBurace

  In WinXP SP3, I have a .BAT file on a mapped drive. When I try to run this .BAT file (or even right click-edit) it gives me: --------------------------- Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item. --------------------------- OK --------------------------- This happens with any .BAT file, no matter what is within the file. If the file is on my local computer (like C:) it will run just fine. If someone else runs it from another computer (on the same mapped drive), it runs just fine. I have full permissions on the drive; I can edit/delete/save/write/create in that folder and/or .BAT file and I've ruled out permissions being the issue. It seems like a security prevention, but I can't tell what it would be. It would have to be something on my PC, but I don't use any 3rd party software. What would cause this error?

• Set Up Remote Desktop at Home

  - by Rev

  I'm sure this has been asked before, but I'm unable to find a clear set of instructions. I'm currently using LogMeIn Hamachi to enable Windows 8's Remote Desktop feature on my home computer (running Win8 Pro x64). Unfortunatley, I can't use this method to access my home computer from my Surface Tablet, as I can't install in the Hamachi client. So how can I set up Remote Desktop without using LogMeIn Hamachi? A link to a noob-friendly tutorial would be greatly appreciated. I haven't been able to find anything that I understand (and I am pretty technical, router stuff just stumps me for some reason). EDIT: And I don't want to use a third party service like TeamViewer, in my experience those tools are laggy and quite horrible. The Remote Desktop feature has been excellent.

• Wired connection not working

  - by YokoBlac

  I am using a Acer Aspire One. Here is the Ubuntu Wiki Page about my computer. I have a working wireless connection however when I plug a cat5 (Ethernet) cable in the lights flicker on the computer, but then nothing happens.

• Can a processor upgrade cause BSOD?

  - by Daniel

  I Had the following hardware setup: Phenom II X4 945 Asus M4A97 4GB DDR2 OCZ Radeon HD5850 OCZ Agility 2 120 GB Windows 7 x64 Pro Fully updated (latest drivers and windows update patches) Then I bought an used Phenom II X6 1090T and installed it without formatting. Since that my computer started BSODing almost every time I'm playing any game and with different error messages, like: page fault in non-paged area bad pool header the video memory manager found a problem error in dxgmm1.sys(or something like that) And when it doesn't BSOD the game simply crashes. I have tried: Updating BIOS Reseting BIOS to defaults Reinstalling Video Drivers Installing the latest DirectX All that's left is to do a full format and I don't want to do that since it's going to be a lot of work to fine tune windows to my preferences again. So is my "new" processor defective or do I really need to format the computer? Update: I use a (properly installed) custom cooler from Coolermaster and both the BIOS and the Open Hardware Monitor(Application) attest the CPU is not overheating, so I guess the CPU its defective and since I bought it from a guy over the Internet I'm probably screwed

• Wi-Fi or Bluetooth to USB converter

  - by yerzhik

  Is there a device, that works without a driver, you just connect it as usb, and receive any signal sent to it as if it were COM Port wired connection? For example, such a device that gets data sent to it by Wi-Fi network or Bluetooth and resends it to the USB. Of course it has to be set up once (network name, password etc) and for this purpose you need a driver, but once it is set up, you can use it at any computer without a driver. I have a Bluetooth USB, but I think it can't work without a driver. By just connecting it to any computer you can't find it in device list on another bluetooth device (as phone, etc).

• How do spambots work?

  - by rlb.usa

  I have a forum that's getting hit a lot by forum spambots, and of course the best way to defeat something is to know thy enemy. I'll worry about defeating those spambots later, but right now I'd like to know more about them. Reading around, I felt surprised about the lack of thorough information on the subject (or perhaps my ineptness to input the correct search terms for better google results). I'm interested in learning all about spambots. I've asked on other forums and gotten brush-off answers like "Spambots are always users registering on your site." How do forum spambots work? How do they find the 'new user registration' page? (I'm especially surprised because some forums don't have a dedicated URL for this eg, www.forum.com/register.html , but instead use query strings or even other methods invisible to the URL bar) How do they know what to enter into each 'new user registration' field? How do they determine what's a page they can spam / enter data into and what is not? Do they even 'view' this page at all? ..If not, then I'd assume they're communicating with the server directly - how is - this possible? How do they do it? Can forum spambots break CAPTCHAs? Can they solve logic questions (how?)? Math questions? Do they reverse-engineer client-side anti-bot validation scripts? Server-side scripts? What techniques are still valid to prevent them? Where do spambots come from? Is someone sitting behind the computer snickering as they watch their bot destroy site after site? Or are they snickering as they simply 'release' it onto the internet somehow? Are spambots 'run' by an infected computer somewhere? Do they replicate themselves? etc

• DNS Pointer to old server name

  - by TechKnow Dude

  We have a SBS2003 server that was migrated to a new hardware platform, the computer name has changed but the domain is the same. The desktop's are trying to do offline files to the old server name. There is a nslookup entry for the old server name and a DNS entry for the old server. How do we safely remove the old DNS entry without breaking the computer offline folder storage locally. Can we change the pointing location on the offline file storage to point to the new server name.

• Real time audio streaming

  - by Josh K

  I have a remote computer running OS X. I would like to stream the audio from the microphone input over the network so I can listen to it. Primarily I want to do this because I'm out of the office but still need to communicate with people there. I would like to use VLC, but am not fully aware of the options available. I tried SoundFly (as recommended by another answer) but this didn't seem to want to connect. At this point I should note that I'm using a VPN network to connect to the remote computer (using Hamachi). I can open up ports / etc fine though, so I should be able to do this. Alright, I found Nicecase which does exactly what I want but I would prefer to not have to shell out $40 for it.

• Why does Resource Monitor in windows 7 show half my memory as "Hardware Reserved"?

  - by Brandon

  Does anyone know why in Windows 7 Resource Monitor shows that I have 8 GB of RAM installed on my computer, but I only have 3.2 GB available as 4.8 GB are in "Hardware Reserve". I researched this issue and tried going into msconfig and making sure that in the boot options the number of processors and max memory options were turned off. I also opened the computer up and reseated each of the memory sticks while clearing out any dust that was in there. Some info on the system I am using: OS: Windows 7 Enterprise 64-bit Edition CPU: AMD Phenom X4 9750 Memory: 4 X 2GB DDR2 memory Motherboard: MS-7548 (Aspen) Any help would be much appreciated.

• Use LAN to interface Synergy while having WiFi connected to internet

  - by freonix

  Similar question and solution I have LAN and WiFi connection, with the WiFi connected to internet and the LAN is simply connected via an Ethernet cable between two computers. I need to get Synergy working without compromising the WiFi internet. I've tried the solution above but couldn't seem to work. Both of the computer are running Windows XP. Even setting the LAN IP to static and under the same subnet doesn't seem to work. Anyone with similar situation and got Synergy to work? edit : Refined the question for clarity. Also, the computer are able to ping each other. Remote desktop can be accessed as well. I suspect the problem lies in Synergy's configuration.
