  • SBS2011 Standard DNS suddenly not resolving some domains

    - by Matt
    Suddenly today I am unable to resolve common domains like serverfault.com, facebook.com; but other domains like google.com, cnn.com work fine. This is on a client machine (Win7 Pro) connected to an SBS2011 Standard domain. The only DNS server is the SBS2011 server. The same domains work fine on all client PCs I have tried, and the same ones do not work. Using nslookup, I get 'no such domain' errors for facebook.com, and the correct DNS entries for the ones that do work. When I add Google's Public DNS to my client PC as a backup (primary = local SBS server, secondary = 8.8.8.8), everything works fine for my client PC, but querying from the SBS server directly or from other client PCs are broken (so I don't believe it's a firewall issue). My main question is how can I see what servers the SBS2011 server queries if it doesn't know about a domain? There is nothing in our firewall logs that say it blocked any DNS-based packets, but I also wanted to query based on the IP/FQDN on the servers that the SBS server was likely to contact to find out about facebook.com for example. Update 23/05/2012: It appears DNS is working again this morning for the affected websites. Both the DC on its own and all client PCs can once again access the websites that were not loading last night, as well as the websites that were working. I haven't changed anything overnight, so it appears that there was some kind of temporary glitch, but I can't understand what would have caused it on the network.

  • matlab and gplot

    - by JPC
    Hi, Im trying to find a way to plot a truss in matlab, i can do it by using an adjacancy matrix and the gplot function, but its very long winded approach especially if there are a lot of nodes connected to one another. Is there a faster way to do this? I'm new to matlab and the programming world any help would be really appreciated. JC

  • Why is Lisp used for AI?

    - by Cristián Romo
    I've been learning Lisp to expand my horizons because I have heard that it is used in AI programming. After doing some exploring, I have yet to find AI examples or anything in the language that would make it more inclined towards it. Was Lisp used in the past because it was available, or is there something that I'm just missing?

  • How To Monitor Home Wireless Network Connected Devices Bandwith

    - by GWLlosa
    (Originally posted on SuperUser, not sure if it might be better suited here) I have in my home a standard Comcast cable internet connection. I have it going from the wall to a cable modem, and from the modem to a late-series Linksys router, which provides wired and wireless networking. The vast majority of the users are wireless connections. For day-to-day tasks, this connection is fully sufficient for all my needs. However, on regular occassions, we have social gatherings that involve many people bringing laptops and other PCs and using the network and internet simultaneously, frequently for gaming. I have no administrative oversight over these machines; they have been known to be riddled with spyware and/or bloatware or be running torrents, legal or otherwise. The only reason I care is that on a regular basis, one of the machines will flatline my internet bandwith, and consume it all in order to upload/download/spam people/whatever. When this happens, the latency of the connections for gaming and the like becomes unacceptable, and everyone suffers. My question is: Is there a system I can set up whereby I can easily monitor the various systems connected to my wireless connection, see how much bandwith each one is using, and for what ends? That way, at a glance, I can spot the offending machine and kick it from the connection, without having to go from machine to machine, checking each one's "bandwith used" properties manually, and dealing with the owner's indignant protests all the while. I understand this will likely involve 3rd-party software and/or hardware; my issue is I don't even know where to begin.

  • fread and fwrite are not recommended for use with structured data

    - by forest58
    A book beginning linux programming 3ed says "Note that fread and fwrite are not recommended for use with structured data.Part of the problem is that files written with fwrite are potentially nonportable between different machines." What does that mean exactly? what calls should I use if I want to write a portable structured data reader or writer? direct system calls?

  • Convert MSAccess Project Management Application to PHP/MySQL: Which Methodology?

    - by zzapper
    I've got to convert a not terribly complicated bespoke project management system from MsAccess Application to PHP/MySQL. I've been programming for donkey's years but embarrassingly know practically nothing about modern methodologies. So the old 'learning curve' versus 'improved efficiency' conundrum rears its ugly head once again. Although I've Googled up some stuff I don't want to prejudice your suggestions, where would you start, I'm at your mercy?

  • Why are there so many DB management Systems ?

    - by mr.bio
    Hi there , i always asked myself. Why are there so many DB management systems? I am not an DB expert and i never thought about using another DB than mysql. Programming languages offer different paradigms, so there it makes sense to choose a specific language for your purpose. What are factors to choose a specific DB management system ?

  • Task scheduled to wake laptop - only works when lid is open

    - by JD Pack
    I am running Windows 7 Starter on an Acer Aspire One laptop. I want my laptop to automatically run a task (backup the HDD to a network drive) once a week in the middle of the night. I scheduled the task in "Task Scheduler" and checked the box to wake the computer to run the task. I also changed the advanced power settings to allow wake timers. This was half of the solution. It now works flawlessly when the lid is open... the computer can wake itself up from either sleep or hibernate mode to perform the backup. When the lid is closed however, its sleeping beauty. Any ideas? I don't want to have to remember to open the lid once a week. It sort of defeats the purpose of an "automatic" backup. Update: I discovered that it can wake from sleep (or hybrid sleep), but not from hibernate when the lid is closed. This is good news. I'd still be curious about how to get it to work from hibernate, but I'm pretty happy about waking from sleep at least.

  • C++: GUI libraries for embedding into an interpreter

    - by sub
    I've got my interpreter up and running - quite bug-free and stable for now - now I want to add some visual options to my language to play around. What is a good GUI library easy to use and mainly easy to embed and "link" to my programming language? What general rules do I have to follow? I'm currently on XP with Microsoft Visual Studio 2010.

  • Show a DB as a directory (Like Sharepoint Does)

    - by Zyd
    Hi, My team and I are programming a sort of Document Manager and the idea is to store them completely on DB. Is there a protocol or Extensions that allows us to show a "Virtual Directory" or files that are really non existent (only in DB). How does Sharepoint do this? I understand that Sharepoint uses WebDav but it implies that the files do exist physically somewhere. We intend to develop this application on .NET 4.0 and deploy it on IIS. Any suggestions? Thanks in advance

  • Office 2010 OCT Outlook Filepaths

    - by vlannoob
    I'm playing around with customizing Office 2010 installs on my network, normally I just do a full manual install, but as the environment grows and the lazier I get its becoming a pain to do it manually every time. I've read up and downloaded the Office 2010 OCT tool and it looks relatively straight forward - with one exception - the Outlook Profile. I can 'get around it' by just leaving it all as default (or not enabling offline use) but I'd like to customise it slightly so that its all setup no matter who logs onto the PC. The only issue I have, and my question is: In the OCT - Outlook section What do you enter into the Path and Filename for the OST file and the Offline Address book seetings under Enable Offline Use section? I'm sweet with everything else - just that one section, and I think if I bugger that one it will kill the whole Outlook Profile?? It would need to go into each users unique filepath for their profile correct? I have a fair idea of what should be there but I'm struggling with the correct syntax. I know this is a stupid question....but its late in the day and my brain is fried ;) As usual - any and all help/assistance is appreciated ;)

  • What is the technical skill degree of your co-workers?

    - by bonefisher
    For now it has been around 4 years that I work as developer. Most of my team mates, from their tech-skill, programming ability and code practices view, are somewhere between junior and senior. In all my previous jobs, there was a real geek who was brilliant at coding/analyzing/lead, but the others were just 'average' programmers. How would you rank your co-workers as good developers from rank 1 (best) - 5 (worst) ?

  • iPhone apps for company-internal use - possible?

    - by Michael Stum
    I hope this is still programming related, as SuperUser doesn't seem the appropriate place. Basically I wonder if it is possible to have Applications that are internal to a company on the iPhone? That is something like a companion Application to an Intranet (when Safari and Mail just don't cut it) which wouldn't make sense on the AppStore (and likely wouldn't get approved anyway). Is something like that possible (without Jailbreaking or doing anything else that Apple doesn't normally want)?

  • Where did my backup files go? Can they be recovered?

    - by Ken
    I just purchased a Western Digital Essential SE 1TB external hard drive from Best Buy at their recommendation. I then exchanged it for a Toshiba Canvio (I think that was the name). I have a Toshiba Qosmio X505-Q898. The Canvio locked up my computer and rewrote some kind of OS file, and erased all the restore points as well as the system image backup (according to Best Buy) just by plugging it in for the first time. Never even got to the install part or anything -- plugged it in and fried my computer. They spent about an hour and a half on my computer and got it back to a somewhat working condition and gave me access to my files. So now they say I have to back it up using my recovery disk and rewriting my OS. Enter the Essential. Brought it home last night, plugged it in and installed everything. Works perfect, no problems. Backed up everything on it. I unplugged and plugged it twice to make sure that everything was on it. Essential told me it had both the HDD and SSD backed up. So I reinstalled my OS. Plugged the Essential in and everything loads right up. Went to retrieve my files and the Western Digital has nothing on it. It shows all my music, pics, ETC. as still being on my computer and needing to be backed up, but since there are no files on my computer now. Where is this information coming from and where did my files go? It's about 810GB worth of files I've amassed over several years. Is there any way to recover data from this? I plan to contact Western Digital and Best Buy, just thought I would check here too. Any advice will be appreciated as a lot of these files are invaluable to me.
