• Is my computer security suite good enough?

  - by The Green Frog

  I have a Windows machine and I run AVG free antivirus, Windows Defender and firewall, Spybot Search & Destroy, Outpost Firewall, and Prevx. I am just checking because I think I might have turned something up. Is this security suite good enough?

• Login to OS X Server User Account from Local Computer

  - by Brod Wilkinson

  I have OS X Server installed on a mac mini. I've created several User accounts, one of which is Account Name: Bob Password: abc123 From the Mac Mini's login screen I can choose "Server" (main account) "Bob" (Bobs account) and "Other..." OS X Server Accounts, from "Other..." if I input Bobs credentials it will log me in. I also have a macbook air, I would like to be able to select from the Login Screen "Other..." input Bobs credentials and have it login to Bobs account, or any other User Account for that matter. My Server is setup as private with the server address: server.network.private Following some googled instructions as well as apples very own instructions I have: Setup an Open Directory with Username: diradmin Password: abc123 Then on the macbook air gone into System Preferences > Users & Groups > Login Options and clicked Join next to Network Account Server, input my server (server.network.private) with diradmin credentials and its connected. Great. I've also ticked Allow Network Users to Login and Login Window and selected All Users. I was assuming this would allow my macbook air to login to the "Bob" account by selecting "Other..." from the login window although there is no "Other..." option. I then setup a VPN, basic credentials, logged into it on the macbook air and still not much has changed. I am able to share screens with the "Bob" account form my macbook air by logging in by clicking Share Screen... from the Finder under Shared > Network Server and then clicking Login In but this obviously requires the macbook air to already be logged into an account before it can share screens which is not suitable. Is there any way to simply login to the OS X Server User Account from the macbook air's login screen via the "Other..." like it does on the mac mini's login screen? Thanks in advance. Operating System: OS X 10.9 Mavericks OS X Server: Version 3

• A Domain Admin user doesn't have effective Administrative rights on a Domain Computer

  - by rwetzeler

  I am a developer who is setting up a virtual domain environment of testing purposes and am having trouble with the setup. I have created a new DC on a new Forest... call it dev.contoso.com. I have setup a virtual internal network for all machines that are going to be apart of this virtual test environment and have given each machine a static IP address in the 192.169.150.0 subnet. I have added machine1.dev.contoso.com to the domain dev.contoso.com. I have also provisioned a user account (adminuser) in the domain and made that user a member of Domain Admins group. Upon logging into machine1 using my newly created Domain Admin account, I cannot access/run any files on machine1. When I go into the advanced permissions for the c:\ folder and goto properties - Security Tab - Advanced - Effective Permissions and search for the dev\adminuser (mentioned above), I get an error saying: Windows can't calculate the effective permissions for admin user What do I need to do to get Administrative rights on Machine1? I am using Server 2008 R2 for both the AD controller and machine1.

• Computer can't boot

  - by zETO

  I have a 1 year old PC and the last weeks, when I press the ON button the PC doesn't power on ( Like I didn't press the ON button ). I have to plug and unplug a few times the power cord in order to make it work. At the start this happened once in 10 boots. Now it happens much more frequently to the point that when I press the power on button it never even opens if I don't do the cord switch thingy. Very rarely also, the PC shut downs for no reason and no warning, even when idle. The important fact to note here is, the green light on the motherboard is always on, even when the PC doesn't power on. What should I do? Is it a Power Supply failure or a motherboard? My power supply is a high end corsair model, AX850 and my motherboard a high end ASUS.

• Computer loses all installed programs and appears to return OS-only state

  - by Jake

  This is a story regarding 3 laptops of different brand and models. On separate occassions, I configured each of these Windows 7 / Vista computers with the necessary configuration and applications (which are supposedly the same actually), e.g. join office domain, same windows updates, microft office etc. These machinese were configure in our office in Singapore, and then they were taken to India for use. Someday in India, when booting up the laptop, all went fine except when it reach the log in screen, it was no longer possible to login with domain credentials. Logging into the laptop local admin account will lead to discover that the machine has returned to "OS-only state". All the configurations and applications were gone. The actual user profiles are still in the C: drive so files can still be retrieved, but under Control Panel Uninstall Programs it is evident that at least the registry is corrupted. The above scenario happen to the first 2 laptops. For the third, the system reports "Operating System Not Found" on boot up. I cannot think of any reason except to suspect a power fluctuation issue. Question is, will a power issue create this behaviour? What else can cause this issue?

• Software available for singing "lessons" via computer microphone?

  - by drozzy

  Looking for a software to help my friend learn to sing. Can't seem to find anything on googles. Does there exist software (preferably downloadable and from this century!) that records one's voice and then analyzes it to see how "accurate" it was. It would be great if it also had some kind of "lessons" of some sort, and not simply sound recorder that shows waveforms. I can't imagine it would be so hard to implement, and there probably is one out there - I just can't find it. Any recommendations are welcome. Thanks.

• Computer won't power on

  - by briskmojo

  Was working fine for over a year, now won't boot. LEDs on the GFX card and one on the MOBO labeled PWR glow when plugged in, but nothing happens when I push power and shorting switch pins does nothing either. If I pop out the CMOS battery and put it back in then try the fans lurch but nothing happens. Shorting the 15 and 16 pins turns the PSU on, and when the 24pin connector is attached to the MOBO it will start up briefly then stop. If I plug in the CPU header it returns to what I described, no power but will lurch after replacing the CMOS battery. Should I be shopping for a new PSU or is there another problem maybe?

• How to calculate power/energy taken by computer and screen

  - by r0ca

  I need to investigate how much power my linux machine uses per week. I can take a look at the PSU but I would like to know how to calculate the average use of power it takes. I also need to know how much power a CRT screen use per week. Do I need to check the PSU Watt unit and Screen Watt usage and just add both to have the results? P.S. My english is not good, sorry about that! P.P.S. My question is not related to: http://superuser.com/questions/9946/how-to-choose-a-ups-calculate-power-for-a-new-pc

• fast way to find network user computer on domain hogging all wan bandwidth

  - by dasko

  i have a network of about 40 domain users and i have huge latency wan issues, like 1400ms for google.com pings. I have noticed that the problem goes away after everyone goes home for the day. I would like to know if i should use something like a hub with wireshark on the router or modem to see if there are any irregular activity. I am open to suggestions but i need to isolate which user has the bug. I am assuming it is either downloads or someone spamming out heavily and not knowing. It would be best to trace to ip number so i can just look into dns and find the pc hostname with the problem? This is the first client i have this problem with so never really needed to address it before but not suprised as users don't actually listen to any best practices that we have suggested. Please help, thanks. just to update, pc's to routers and other computers have ping latency of 1ms so it is right after i hit the wan, using tracert to a web site (random), that i get the massive delay in the responses. As well this is a dsl line with 5mb down and 650kb up (maybe upload saturation?) thanks.

• Does static damage computer speakers?

  - by incarna

  I recently got a new pair of Klipsch Promedia 2.1's for my laptop. I unplug my laptop a lot to take it around but today the audio plug touched my plug for my monitor and a bit of static came out of the speakers. I've heard some rumors that static can damage speakers but I've never investigated this problem myself since I previously used a desktop and never unplugged them. The volume was at a normal volume- am I just being paranoid? Or could having the speaker port touching other bits of metal damage my speakers?

• XP Computer won't start (Missing/Corrupt 'System' file) - recently added new hard drive

  - by qwerty2

  Hi all, Pulling my hair out here. I recently replaced my D: 1TB drive (not a system drive) with a new 1.5TB drive. I loaded Windows XP, formatted the new drive and it was showing as working fine, alongside my C: windows system drive. I restart my machine and all of a sudden, Windows doesn't load and instead I get: "Windows could not start beause the following file is missing or corrupt" \WINDOWS\SYSTEM32\CONFIG\SYSTEM I don't have the original XP installation CD, although I do have another copy of XP, when I try and boot to it, I get the blue 'STOP' screen after it attempts to load the setup utlity for about a minute. Can someone please help? When I set up my new hard drive as a primary partition did this someone screw up my C: hard drive? Did it perhaps unmount it somehow? Any help would be fantastic. Thanks

• Domain joined computer unable to access servers through VPN

  - by kscott

  Our servers are in a virtual off site hosting center, our office has a vpn connection to the data center, but for reasons I don't understand we also have to connect to the Citrix Access Gateway (CAG) client in order to access the servers. I am a programmer with rather limited ops knowledge including a weak grasp of networking and terminology. Bear with me. I was just given a new laptop, which is a 64 bit Windows 7 system unlike my previous 32 bit Windows XP desktop which was able to connect without issue. My laptop has been joined to the domain so that I login with my AD credentials, I am able to connect to the CAG and get authenticated, and after doing this I can ping our servers and they resolve to the correct internal IP addresses, but I am unable to use remote desktop to the servers, connect to SQL servers through my local SQL Management Studio, navigate to them through the file system, or view any of our internal intranet websites. All of which I was able to do previously. I have tried turning off my Windows firewall and the problem remains, the DNS servers are set to the correct IPs of our domain controllers, and the ops guys here are a little stumped. Does any one have any suggestions?

• Computer restarts without warning; code bcc116

  - by Robert C.

  Processor: Intel i5 4430 4-Core 4x3Ghz Motherboard: msi h87-g41 Graphics Card: Nvidia GTX760 Power supply: eps-750 cm RAM: 8GB I bought a new assembled gaming PC which worked fine for a few days. Then it started rebooting without warning. After it restarts windows 7 gives me an bbc 116 error code. Apparently it's something to do with my video card, either it overheating or wrong drivers. I've installed the latest driver from Nvidia for my graphics card. Since it's brand new it can't be dust, I'm running it with its lid open to see if the problem persists. I'm also running prime95 now to see if it tells me anything else. Using core temp it tells me that my CPU reaches up to 95° celsius with the blend stress test from prime95. Aaaand it just peaked to 100°. Of course it doesn't reach these temperatures at all while idle/gaming. I'm gonna let prime95 run for a night and to see what happens. Until then does anyone know what I should do next?

• EEE PC dropbox server running 24/7

  - by microspino

  I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better). Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web. Print Server: I have Samsung SCX 4521F (fax/print/scan/copy), Samsung ML2010, HP Laser jet P1006, HP Color Laserjet CP1215, HP Office jet pro K8600, HP Design jet 500. All of them now are connected using little print servers and I want to get rid of them hooking everything to this mini server. The fax/print/scan/copy machine need to stay connected to a PC to make me able to use the software that comes with It. The mini server would save me on this too. Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server. I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously. I'd like to listen some advice from You. Best of all would be: If You have something similar running for a long time If You disagree with this hardware choice and If You would suggest some other device. If You see any issues with my printing setup Anything else ;) My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.

• DNS server at router level vs. computer level

  - by Craig

  I've three questions. Is it better/faster/optimal to set up your server's preferred and alternate DNS servers in your OS's network settings or in your router settings? Will it cause problems if it is set up in both places, both pointing to the same IPs? I am running Windows and I have my network assign a static IP to one of my computers. This doesn't allow me to obtain the DNS server addresses from my router automatically. Is there an IP I can put in that will cause it to take the DNS server addresses from the router?

• Switch computer off automatically when the internet is disconnected

  - by Vin

  Is there any free software that will detect the status of internet and shutdown the system when the internet disconnects? Or (more generally) can something run a task when the internet disconnects, and I can route it to shutdown the machine? I am downloading things overnight. But my problem is that sometimes the internet connection will be disconnected in the middle of the night, so there is no point in keeping the system running the rest of the night. So I need to avoid this problem by detecting the net connectivity.

• Why a 10 years old software still is so slow even today?

  - by Cawas

  I just noted this question due to a game (which happens to be Diablo 2), but the matter of fact is: why is my brand new mac book pro, made in 2009 with latest technology (tho it's the cheapest one) can't rival my computer which used to run this much faster back in 2000? Really, it was much faster on my AMD K6 450 back in those days, and I could even run two clients at same time with no slow down. I've always had the feeling this machine was slow, but this is a very odd way to attest it. Granted, the machine is smaller, runs on wifi and "boots" way faster thanks to sleep mode. But other than that, what have we evolved after all?! I'm pretty sure this shouldn't be graphical card's fault. Sure if I buy latest technology it will run fast, and probably most people here can confirm this and won't even understand my question. But the thing is, all the hardware is supposedly much faster and better than the stuff from 10 years ago. The software and operating system became more complex, but also more well refined. Now I'm trying a piece of software that is actually 10 years old and it's not getting any better results! Why?

• Building a Media Center PC with Comcast Cable...?

  - by Rob

  Alright - so this might be a stupid question but I've never been all that much into TV. I currently have Comcast cable. I've just got the 'basic' 2-60 package or whatever; I've just always plugged the cable into the back of my TV. I've never had a cable box. Recently, Comcast has been pulling channels off of my line-up. Most recently, the stole the TV Guide channel from me. I'm told this is part of a push to get customers to switch to their digital line-up. But, I'm also told it requires some sort of digital receiver for each TV you've got. I don't want to buy a bunch of these digital receivers and I don't want to pay the monthly rental fee...but I have heard of how awesome media center PCs are and some really cool things they can do. And, I've got loads of PC parts sitting around. So, can someone guide me through this a bit? Are there computer video cards or TV tuners that are going to work with Comcast's digital cable? What kind of price range are we looking at?

• Why not all users can log in to a network computer by using <network computer name>/<user name> form

  - by Haris

  There is a file server in my office that is not connected to my office LAN. In this server there are folders that are shared. This server is connected to a switch and a wireless router. Everyone who wants to access this server uses wireless network connection. They log in to this server by providing user name and password registered to the server. Some people can log in to my office file server by providing user name in (the server name)/(user name) format, while other must use (the server IP address)/(user name) format. Why is it like this? I need everyone can access the file server by providing user name in (the server name)/(user name) format. I have tried to change the %SystemRoot%\system32\drivers\etc\hosts file, as some suggested, but it won't work. Any other suggestion?

• MySQL Workbench sends computer name with login not IP

  - by Android Addict

  I am attempting to connect MySQLWorkbench to a remote MySQL Server. The server has granted access to user@IPAddress However, when I try to connect MySQLWorkbench, it sends user@computername instead. How do I configure the connection to use the IP address instead in MySQLWorkbench? Reference: The remote server is on the local network, so I need to use the local IP address assigned to my client. EDIT What I have tried so far: from the server: mysql -u user@IPAddress -p --host=(ServerIPAddress) Returns: mysql> So that tells me the user account is operational. Furthermore, I confirmed it exists using: select user from mysql.user; returning a table of all users, of which the user I am using is present. I have also opened the port 3306: sbin/iptables -A INPUT -i eth0 -s clientIPAddress -p tcp --destination-port3306 -j ACCEPT Still I encounter Access Denied

• One Mac computer with multiple network connections?

  - by Kyle Lowry

  I have a Mac (OS X 10.5) that I would like to connect to a dedicated/isolated Internet connection (one that is not connected to the LAN), and a LAN. The LAN is set up with its own, separate, Internet connection which is shared by several dozen computers (and is quite slow). I want to set it up so that the Mac uses its own dedicated Internet connection (on a different account with a different company) for its Internet access, but can still access the local area network as well. How can I configure the Mac & the network to allow this?
