  • Windows 7 RDP Problem - connecting to external zone with computer names

    - by alex
    I recently installed Windows 7, all is well so far, apart from using RDP to access computers outside my domain. We use a datacenter, outside of our domain. I was using Windows Vista before (not sure if this is relevant) - I could RDP no problem to the machines (using their machine names - Web10 for example) I have changed my IP address to be the same as it was when i was using vista We use a draytek firewall - we use DMZ Host to map my IP to an external ip- which is allowed to access the datacenter I've disabled windows firewall When i try to connect in Remote Desktop client, using Web10, I can't connect, however, if I enter the actual IP address, i can. I have run out of ideas... any help is appreciated!

  • Computer temporarily freezes and then resumes

    - by trizicus
    This happens on ALL operating systems (7, Ubuntu, etc.). What happens is everything for 1-3 seconds becomes unresponsive, I then hear what sounds like my other internal hard drive 'spinning up', and then viola everything is responsive again. Note: Already ran SMART tests, no issues at all. I think issue is that the HDD spins down and when need it gets 'turned-on' (OS settings turn off HDD's after 20 mins of inactivity) and because my pagefile is on the other HDD it causes OS to temporarily freeze. Need more tips, and insight. Thanks More info: Running Quad CPU, 4GB RAM, Intel SSD, GT 240.

  • Can't browse computer via nlb cluster name

    - by peg_leg
    I have a fileserver nlb cluster, currently set to single affinity, made up of 2 2008R2 servers. We switched the primary node today. Now our Windows XP workstations can't browse to the cluster name (i.e. \fileserver) but can browse to the cluster ip address (i.e. \192.168.1.1) and can browse the member server by name (i.e. \filesvr1). I remember having a similar issue when we had to change a registry setting to allow Windows XP boxes to see another file server that was in a failover cluster but had to be referred to by another name (\thisfileserver instead of \fileserver). Convoluted, for sure, but it helped to prevent any code changes from happening. Well all of the programmers have their code on \fileserver and we can't have them switch their links every time \filesvr1 supercedes \filesvr2 or vice versa. I can't remember that registry setting that allowed the file server to ignore that it's being called by the wrong name. HELP!

  • Computer slow after installing 32GB RAM

    - by John Gilmore
    I'm currently running very large network simulations for my PhD research, for which I need lots of RAM. I have a Core i7 2600K processor with a Gigabyte GA-Z68AP-D3 motherboard, running Windows 7 professional 64bit. I bought the system with 8GB (2x4GB) DDR3 1600 MHz Corsair Vengeance RAM and the system ran like a dream. I'm planning to upscale my simulations so I removed the 2x4GB RAM and installed 4x8GB DDR 1600 MHz Corsair Vengeance RAM. When I rebooted the system, boot time was much longer than usual (10 mins just to get to login screen). After logging in, the whole system was unresponsive. I tried playing some games (Bioshock 2), but it was unplayable. I've not had this problem before and I have an ATI Radeon HD 5850 graphics card, so that's not the problem. The only thing that's changed is the RAM. I've looked through the specifications of Windows, my motherboard and my CPU and they all state that 32GB of RAM is supported. Does anyone have an idea of what's going on? Any help would be greatly appreciated.

  • Windows 7 security and Avast antivirus turned off by themself

    - by Simon Verbeke
    I was just browsing around when at once I got messages that UAC, windows defender, Avast, etc. got turned off, without me doing anything. Then my PC turned by itself. I'm now running virus scans and I checked my eventlogs, but found nothing yet. Windows Update also failed to install a new definition after I rebooted. Any idea what this could've been? EDIT: Forgot to mention that everything was turned on again after rebooting. I have since the reboot got nothing abnormal.

  • How to merge several detached signatures from different people into one?

    - by Petr Pudlák
    A group of people wants to publish a file and they all want to digitally sign the file as different recipients of the file will have different chains of trust. For simplicity, it's desired that there is only one detached signature file with all the signatures, so that the recipients don't need to check them one by one: foo.tar.gz foo.tar.gz.sig However, for security reasons, every person needs to perform the signing on their computer, it's not possible to create the combined signature by having multiple private keys on one computer and performing the operation with one command. Is it possible with GPG to somehow merge detached signatures of a file from multiple participants?

  • Security Issue with Active Directory

    - by Will McCloskey
    The retard who was on the built-in Administrator login somehow (and this is what I'm guessing being as he is not here and I was not present when this occurred - Supposedly it was an "ACCIDENT") Denied the built-in Administrator account and every other account except for his personal one access to our domain - ie "Example.net" not just active directory or anything. I've been trying for literally 2 hours to find some sort of way to take control of the domain through the built-in Admin account with no success; I can't even open Active Directory. I'm not aloud to open DSA.MSC and there's no way for me to take ownership. Any ideas?

  • PC3200 RAM in Older Computer?

    - by skaz
    Hello all, I am inheriting a Dell Dimension 8200, but it needs RAM to get up and running. I have PC3200 sticks lying around, but I am not sure how to go about figuring out if the RAM is compatible, as RAM has always confused me. Here is the Dell Dimension 8200 Tech Specs: http://support.dell.com/support/edocs/systems/dim8200/specs.htm For RAM, it says: Memory type PC800 (non-ECC) I don't know if that is just the kind that comes with it, and I can put in PC3200 (I think, if it worked, this would run at the lower rating? Is that true?), or if that means only PC800 is compatible. Any help would be appreciated.

  • Computer wont start, just blinks on and off

    - by Ryan
    This is really strange. I had a comp that was working fine for over a year, then suddenly it started to shut off, it got so bad that I press the power button and in around 30 secs while booting windows it would shut off, then 20 secs... then 10 secs, then it refused to start all together. So I bought a new PSU (850w Thermaltake, the old one was 550w corsair) thinking that was the problem, I fitted the new PSU now and its the same thing, I press the power button and my fans start for a split second (they have led lights on them, so the lights come on) and then everything goes off again. I thought maybe it was my power button that was loose on my comp, luckily I had another chassis near by so I disconnected the powerSW from the old one and put ran the powerSW from the new chassis, press the power on the new chassis and same thing, it blinks for a split second and off again. Double checked connections from the PSU to the cpu power as well as board mobo power, its tight. It's pretty unlikely both the PSUs have the same exact problem so am lost... Suggestions?

  • Can't see a Windows XP computer on the network

    - by user56614
    I have two PC's connected to the same router. One is running Vista Home Premium and the other is running XP Pro. I'm trying to reach the shares of second PC from the first PC. I've enabled file sharing on the XP PC, I've disabled firewall and defender, and I can successfully ping it from the Vista PC. Both computers are set to the same workgroup "WORKGROUP". However, if I try to type "\\192.168.1.2" in Windows Explorer (192.168.1.2 being the IP address of the XP PC), I get a message: "Windows can't access \\192.168.1.2... Error code: 0x80004005 Unspecified error". And If I type "net view \\192.168.1.2" in command prompt, I get "System error 53 has occurred. The network path was not found." Am I missing something trivial?

  • Why can't I install MySQL on my computer?

    - by Bea
    I have read a lot of tutorials, but I am still having problems. What I tried: I downloaded mysql-5.5.9-winx64. All that I read says that I can run Setup.exe, but there is no such file in the download. The other option I know there is, is including \mysql-5.5.9-winx64\bin in the PATH variable and then trying to execute the mysql command. When I do that, the error I get is: ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061) I then downloaded mysql-5.5.9-winx64.msi, which is easier to install, but once I followed the instructions and it was installed, I got the same error executing the mysql command. How can I use MySQL? EDIT: I've now removed everything I installed, and I want to start from scratch.

  • run a 2nd computer as an extra processor

    - by MMK
    I have a laptop with a busted l.c.d., but otherwise works fine with an external monitor. I was wondering if it is possible to connect it to my main pc as an extra processor(main pc is getting old, it's only single core processor) and if so how? I currently have them connected with a network cable so that I can access the laptop's hard drive but would like to use it to give my pc a bit more power. Both my pc and my laptop have 2 gb ram and are running windows vista sp2

  • Bypass insane corporate security system

    - by user1665154
    I'm searching for a posibility to bypass the "Firewall" for 3-4 days. I've tried everything I know, so I ask here for a answer. We have no admin rights and the OS is Windows Vista There is an HTTP Proxy with NTML Authentication (only way to access the internet) It requires a username and password We use smart cards, in fact I have only a user number and a pin. Port 80 and 443 are open - I have an SSH server at home which is listening on port 443 The problem is that I need this proxy to connect to anything. Internet access only works in IE, Chrome, Firefox when I set the proxy settings to "use system proxy settings", "proxy-autoconfig (proxy.pac)" or when I enter the proxy inside the proxy.pac file. However I can't understand where they take the username and password which the Proxy requires. What I've tried was using cntlm to connect to the proxy with authentication (altought I have no PW and username) and PuTTY to create the SSH tunnel over port 443 whit the SOCKS Proxy which I've created with cntml. I've never found some SSH client which includes a "use system proxy settings" function.

  • Assembling a number-crunching computer [closed]

    - by tugrul büyükisik
    What is needed to make a GPU fully fed by CPU? Comparing their flops/s is enough? For example, if i could manage to make a very old(pentium-3) CPU with one of Nvidia-Fermi GPU, it would not be able to fed the gpu with data per sec. What is the criteria to fit CPU to GPU exactly when OpenCL or some similar work needed? Of course RAM and BUS will be chosen in a similar way but how exactly? Assume each GPU-core will calculate a sqrt and a division and an adding for 100 times for every itearation. Thanks.

  • Computer won't stay powered up

    - by Android
    I have just tried to turn my PC on this morning and it won't stay powered up. It will come on as normal for about 5 seconds, not quite long enough for the monitor to wake up. Then it will power off. After about 2 seconds it will start again, it will continue like this until I pull out the plug. Plugging it in again doesn't restart the cycle although pressing the power button does. I have tried to clear the cmos but beyond that I have no ideas. It was working perfectly when I put it in hibernate last night.

  • Fastest security check of file tree on NFS

    - by fungs
    I am currently experiencing very bad performance using the following on an NFS network folder: time find . | while read f; do test -L "$f" && f=$(readlink -m $f); grp="$(stat -c %G $f)"; perm="$(stat -c %A $f)"; done Question 1) Within the loop permissions are checked using the variables grp and perm. Is there a way to lower the amount of disc I/O for these kind of checks over the network (e.g. read all meta data at once using find)? Question 2) It seems like the NFS isn't tuned very well, the same operation on a similar network link via SSHFS take only one third of the time. All parameters are auto-negotiated. Any suggestions?
