• Advantages / disadvantages of having DynDNS access on a computer vs the router

  - by Margaret

  I have a shiny new toy, a Cisco Wireless-N Gigabit Security Router with VPN (WRVS4400N). While looking through the instruction manual, I discovered that it had support for DynDNS built-in. We've currently got the DynDNS client running on one of the servers (that people SSH to, as documented in this question); but the reason for the router update is to move away from SSH to VPN. To that end, is there any difference in behaviour/functionality/maintainability to run it off the computer, as opposed to the router? Thus far, DynDNS has more or less a set-and-forget setup, but since the feature was there, I wanted to know if it was a better location for the process...

• this operation has been canceled due to restrictions in effect on this computer

  - by Dan

  I have this HUGELY irritating problem on Windows 7 (x64). Whenever I click on ANY link (that exists on a Word document, excel or Outlook), I get an alert box with the message: "This operation has been canceled due to restrictions in effect on this computer" I have been scouring my settings and the internet for a solution, but to no avail. Has anybody else encounted this problem? It even happens when I click anchors in word documents i.e. I can't even click on an entry in a Table of Contents to go to the appropriate page - I get this same error then. Is this a Windows 7 thing? Anyway to turn this off?

• How to find the computer name a user logged on to

  - by V. Romanov

  Is there a tool or script or some other way of knowing what computer name a specific user is currently logged on to? Or even was logged on to? Say the user "HRDrone" is working on his machine whose hostname is "HRStation01". I, sitting at my sysadmin desk, only know that the username is "HRDrone". Any way i can find out that he is logged on to "HRStation01" without asking the user? AD event viewer? anything? Thanks!

• Windows 8 cloned drive in 2nd computer

  - by Mark

  I did the Windows 8 Pro upgrade machine w/ 64GB SSD. Finding 64GB not enough, I ordered a 128 GB SSD (Samsung 830) while planning to use CloneZilla to clone the Windows 8 OS to it. I might try using the 64GB SSD (with the Windows 8 upgrade on it) as a boot drive in a backup machine. I understand that I need to do some registry work to make it happy about the SSD 'transplant,' but I am worried about having to register the same activation key on 2 computers. Am I at high risk of getting 'deactivated'? Note that the backup machine is only used when primary computer is off.

• Strange email coming from/to my computer

  - by Micah

  I'm running smtp4dev on my machine to trap anything going in/out of my computer on port 25 for testing purposes. Every so often this email gets trapped and I have no idea what it's from. I have Microsoft Security Essentials running on my machine and it hasn't identified and viruses or anything so I'm not sure what's going on. Here's the content of the message: Received: from [125.180.72.4] by 173.162.7.130 SMTP id O2Ncv62Ghig1vR for <[email protected]>; Fri, 24 Jun 2011 20:36:15 +0200 Received: from [125.180.72.4] by 173.162.7.130 SMTP id O2Ncv62Ghig1vR for <[email protected]>; Fri, 24 Jun 2011 20:36:15 +0200 Message-ID: <[email protected]> From: "" <[email protected]> To: <[email protected]> Subject: BC_173.162.7.130 Date: Fri, 24 Jun 11 20:36:15 GMT MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_000D_01C2CC60.49F4EC70"

• Restore complete PC from another computer

  - by Mirage

  I have a few friends which keep on coming to me every month to format their laptops and then reinstall Windows. This is time consuming. Is there any way that I can make an image of their full system on my Harddrive and then restore to their Laptop from my computer? Edit: What I want is I have the image of the whole laptop on my desktop. The laptop is formatted with no OS. I have no CD/DVD to put in laptop (as the image is 15GB). How will I trasfer the image from my desktop to the laptop without using CD/DVD? Any option for booting via network, etc?

• CPU fan twitching phase leds blinking - computer won't boot

  - by SooX

  I have a big problem that I got today. Yesterday computer was "on" normally, I went to sleep without shutting it down. When I woke up, I heard a strange sound and was unable to bring it up from hibernate. I unplugged the PSU. When I plugged the PSU back in, the sound came back. When I opened the case, I saw the fan "twitching" like it is about to start and fan LEDs were blinking. Also, motherboard LEDs were blinking in the same pattern - the first green one has more of luminosity then others. When I cut down the power with 0/1 button on PSU, the fans continue to make sounds like the machine is trying to boot before the capacitors run out and the power dies. Does anyone have a clue what to do? I tried disassembling everything but that doesn't work. I will try with friend's PSU later today.

• run two apache servers on one computer

  - by harry_T

  I would like to run two XAMPP apache servers and mysql on one Windows computer. My first idea was to run one under directory XAMPP, the other under XAMPP_B. Why you ask? I have two applications that have to be in the "root" directory of localhost. Both servers do not have to be active at same time, so I don't think I will have any conflicts I will have to modify my.cnf in mySQL httpd.conf, apache_start and maybe other config files as well. Or maybe someone can suggest a better way...

• Running Java 32bit and 64bit on same computer

  - by Joris Meys

  I ran into a rather puzzling problem, trying to install Vuze 4.2.0.2 on my Windows 7. I have a Java 6 JDK 64bit, but Vuze complains that it can't find a correct 32bit JRE. Yet, as far as I know it shouldn't matter which Java is installed on the computer. (See also these answers). Now I was wondering : if it makes sense running a 32bit and a 64bit Java on the same machine, Whether that is possible, and if so what I should pay attention to in order to make sure that the correct Java is found. Thank you in advance PS : I have my reasons no to use the latest Vuze, so please don't tell me to update Vuze. I know.

• How to sync a folder on a remote computer to a server on a domain

  - by Pierre-Alain Vigeant

  We have a small remote office that often share data with us. I learned that the data is shared as a email attachment, but that obviously leads to versioning hell and overriding. I am looking for a way for then to synchronize a folder directly on our main office domain controller. I personally use LiveMesh, but I would like a tool that is synchronized to our server directly without a 3rd party hosting the data, since we already have an online backup service taking care of the offsite backup. What enterprise class tool would let us synchronize a folder from a remote computer that is out of our domain, into our the file server of our domain? The synchronization has to be two-way, e.g.: Someone from the remote office will create an invoice. Someone from our office will review it and make modification to it. The remote office need to see the change. Our server is on Windows 2003.

• Play system sounds from one computer through another computer's speakers?

  - by kevinconner

  I have a Mac and a Windows PC at work. I use both at the same time with Synergy and SynergyKM, which is a great setup for me. The Mac has built-in speakers and the PC has a sound card, but no speakers. I don't want to get speakers for use at work; instead I'd rather just have all sounds from both computers play through the Mac's speakers. Is there some sort of audio service I can run on each computer to accomplish that? I would want: System alert sounds, like you configure in the Control Panel Sounds from videos in a web browser, including from Flash

• Windows 7 Computer Maintenance - Restore removed Desktop Shortcuts

  - by HaydnWVN

  I'm aware about the inbuilt nightmate 'tool' of Microsofts which is making every network administrators job a nightmare (if left turned on). In short it'll happily delete every desktop shortcut to a network resource. We have it disabled by default. My question is related to recovering these shortcuts, Windows doesn't seem to dump them into the Recycle Bin and although you can 'restore previous versions' of the Desktop folder, you are unable to do it with the user logged in... Rather a problem if you only have the 1 user account. We have a user who (although the 'Computer Maintenance' tool is turned off) had it come up in 'Action Centre' and chose to run it. I've been unable to reproduce it, but the tool has certainly run (and removed 24 shortcuts from her desktop) although it is still saying 'Windows is not checking your system for maintenance problems'. ?! Very fustrating! Any ideas if these shortcuts are backed up/moved elsewhere so i can easily find and restore them?

• Computer turns on by itself

  - by codedude

  I have a really strange problem here. I have a Asus Zenbook Prime running Windows 7. Whenever I put it to sleep and I have Pandora open (but paused) in my web browser, several hours later the computer turns itself back on and Pandora will unpause itself and start playing. (More often than not this happens at 3AM in the morning so I am less than pleased.) What the heck is going on here? I've never even heard of this happening before...

• "This computer has dynamically assigned IP addresses" error when installing Active Directory Domain Controller

  - by smhnaji

  This is a working Windows Server 2008 that I should install Active Directory on it. I found http://www.howtogeek.com/99323/ and followed the steps. After Additional Domain Controller Options, I'm asked the question "This computer has dynamically assigned IP addresses". As I see, the message states that Dynamic IP addressing has been used for the server, while this is wrong. When I come to Network And Sharing Center, and click on Local Area Connections - Properties - Internet Protocol Version 4 (TCP/IPv4) - Properties, I see that the main IP address (as well as DNS Server) and also all other IP addresses are assigned statically. So it should be OK. I cannot believe any server using dynamic IP(s)! Note: No IPv6 has been set for the server. Please tell me why the error is given and which of the options available, should I choose? Note that it's a production server and is working with many users in WORKGROUP. No change should be affected nor to the IPs, neither to users connecting to the server.

• Computer not displaying anything

  - by Justen

  The computer in question worked last week. It's brand new, never been connected to the internet, up-to-date parts, etc. Last week, I installed some 3D software on it, then shut it down and waited for the license files that arrived this week. I've done this to 4 other PCs with the same hardware and software. I've tried: Hooking it up to 3 different monitors using different video cables 2 other graphics cards and a handful of other things like switching which port it's plugged into before and after a restart. I have the driver disc, and a windows reinstallation disc, but they won't do me any good because no display at all for any interval of time. All the fans are moving: psu, gfx, cpu etc, so I don't believe it's a power issue. Here are the specs I know of: 4GB RAM 8800 GTX 700w PSU Intel dual core (not sure of model) Anyways, I'm open to ideas.

• NLB RPC server is unavailable on the specified computer

  - by Robin Weston

  Hi guys, Firstly, I'll admit that my networking knowledge is limited so as people request more information I'll update this question accordingly. I am trying to create a NLB Cluster across 2 Windows Server 2008 Web Servers. Neither of the machines are members of a domain, and both have 2 NICs (one for processing external web traffic, and one for communicating internally). I have installed NLB on both machines, and have created a cluster on Host A and added itself to it. However, when I try and add Host B (using the address from the external NIC) I get the following error : "The RPC server is unavailable on the specified computer". On Host B I can see that the RPC service is running fine. I can also ping and RDP from Host A to Host B with no problems either. I have disabled the windows firewall on both machines but that had no effect

• Computer randomly shuts down with a fading alarm power button and CD drive

  - by Shad

  I am currently experiencing something very very odd. Having build my PC myself, I have never had any issues (or anything heat related). A few moments ago my computer shut down very randomly and everything goes blank, when I looked down on my case's power button it was fading on and off in such way I've had never seen before. I noticed the CD drive all of a sudden also started blinking randomly. What do you guys think this problem is related to? It is definitely not a overheating issue and I am pretty sure my 600 watt power supply didn't blow because right now I am able to turn it on and boot up the PC but 20 seconds later it shuts down (sometimes doesn't shut down for 2 minutes). I have no idea what this is... My specs are (built by myself): i5 3570k (unoverclocked) GTX 560ti Asrock Z77 Pro4-M motherboard 8GB Vengeance RAM 600W Corsair power supply 500GB of Seagate HD Case: Corsair Carbide 300R

  Hi guys, First of all I would like to stress I'm beginner and probably I'm not doing something right. I replaced my old motherboard (AK35S20C Schuttle) with a new motherboard (Soltek SL-75DRV75). Unfortunately the replacement isn't working as expected. Symptoms are: The computer powers on, works less than a second and powers off. Then it powers on again and so on. It doesn't emit any sound, it looks like it resets very quickly. Do you have any suggestions what might be the problem?

• Cannot copy files from external USB HDD to computer

  - by Thomas Versteeg

  Hello I have a HDD disk connected with a USB converter to my computer. It consists of two partitions, the first one is mounted automatically and I can grab all the files from it, but the second one I have to mount manually as a root in the command line, if I try to open it with nautilus it gives an error. The drive where the problem is is drive sdb1, sdb2 has the same settings but works fine. I am using Debian Wheezy. This is the fstab: /dev/sdb1 /media/usb0 auto defaults,gid=disk,umask=0777 0 0 /dev/sdb2 /media/usb1 auto defaults,gid=disk,umask=0777 0 0 And when I try to copy the files with this command (as root) cp -vr /media/usb0/* /home/user/Videos/ I get these types of errors: cp: reading `/media/usb0/.lang/file.ext': Permission denied cp: failed to extend `/home/user/Videos/.lang/file.ext': Permission denied How can I at least copy the files to my main HDD? I don't need to adjust them I only need to copy them!

• Beam display from any computer to shared display

  - by rcourtna

  There are probably a lot of ways to skin this cat. Looking for the cleanest. In our office, we have a large display in a common area. We want to allow any computer in our office (mac, linux, windows) to output its video on the large display. Since some of the computers in the office are stationary, and it's not practical to run video cables everywhere, it would be preferable to make this all happen through the network. It is also possible for us to connect a dedicated (& networked) PC to the large display. How can I do this?
