• How can I access user files on a disk moved from a Windows 7 machine to an XP machine?

  - by Fantius

  I moved the hard drive from one machine (Win 7) to another (XP) and now certain folders tell me "Access denied". I am logged in as an administrator. I had a different account on the other machine. Neither account authenticated to anything besides the local machine. The old machine is apparently dead, so I can't do anything in there like change permissions, etc. How can I access these files? Edit: After changing the ownerships of all the files and folders on the drive, I am getting a different error. And it is troubling me deeply. "xxx refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location." No change after rebooting. Any ideas? Surely the files are still there, right?

• Windows VPN always disconnects after < 3 minutes, only from my network

  - by hemp

  First, this problem has existed for almost two years. Until serverfault was born, I pretty much gave up on solving it - but now, hope is reborn! I've set up a Windows 2003 server as a domain controller and VPN server at a remote office. I am able to connect to and work over the VPN from every windows client I've tried, including XP, Vista, and Windows 7 without issue, from at least five different networks (corporate and home, domain and non.) It works fine from all of them. However, whenever I connect from clients on my home network, the connection drops (silently) after 3 minutes or less. After a short while, it will eventually tell me the connection has dropped and attempt to redial/reconnect (if I've configured the client that way.) If I reconnect, the connection will re-establish and appear to work correctly, but again will silently drop, this time after a seemingly shorter time period. These are not intermittent drops. It happens every single time, in exactly the same way. The only variable is how long the connection survives. It doesn't matter what type of traffic I send. I can sit idle, send continuous pings, RDP, transfer files, all of that at once - it makes no difference. The result is always the same. Connected for a few minutes, then silent death. Since I doubt anyone has experienced this exact situation, what steps can I take to troubleshoot my evanescing VPN?

• CentOS Installation on a Cisco MCS 7800

  - by William

  Hello, I'm having some problems installing CentOS 5.5 Final (i386) Onto my server, a Cisco MCS 7800. The problem comes very early into the installation. When the welcome screen comes up ans gives you the option on how to boot into the DVD, Ill press enter to go into the graphical installer. The Screen will then have a blinking cursor in the top left of the screen and will never go away (I thought that it just might need time but I let it sit for over 5 hours.) I then booted into it again and tried using Linux Text thinking it was a problem with graphical installer. That didn't work, same problem. Then I tried a DVD of RHEL 5 and got the same problem, both graphical and Linux text. At this point i think its a hardware problem. The Server has 2GB of ECC RAM, 1 Pentium 4 CPU @ 3.06GHZ and 2 WD Hard Drives (80GB) Configured for RAID 0. ( Also there is a option in the BIOS for what OS type and that is set to Linux.) If anyone has any idea what is going on, it would be helpful. ================Edit================== ooshro, typing "text" doesn't change a thing. still stuck at the blinking cursor. I looked it up and its really the same thing as typing "linux text", which as stated in the first part of my question, i've already done.

• wild card redirects issue giving error this webpage has a redirect loop

  - by david

  In my website I changed or better word modified the directory name ""vehicles-cars"" to ""vehicles-cars-for-sale"" when i tried to redirect using wild card redirect my old directory name to new directory name in my web hosting cpanel account. every time when i open pages from that directory i am getting error code. This web-page has a redirect loop. The website is php. The problem is that that my lots of pages from old directory are indexed in googles and they are getting duplicate contents. If I redirect single page it works perfect but there are lots of pages so I need wild card redirect to redirect whole directory . I really need some advice what to do with this problem. Here is .htaccess file code for redirect thanks RewriteEngine on RewriteCond %{HTTP_HOST} ^example\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.example\.com$ RewriteRule ^vehicles\-cars\/?(.*)$ "http\:\/\/example\.com\/vehicles\-cars\-for\-sale\/$1" [R=301,L] i have other wilcard redirect of whole directory with same code and its working perfect here is the code in .htaccss file which is same as above and working perfect for this directory RewriteCond %{HTTP_HOST} ^adsbuz\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.adsbuz\.com$ RewriteRule ^autos\/?(.*)$ "http\:\/\/adsbuz\.com\/vehicles\-cars\-for\-sale\/$1" [R=301,L] so i dont understand whats wrong with the above code please i really need some expert advice thanks again

• Rackspace Ubuntu 12.04 server stuck in initramfs after kernel upgrade

  Can't boot after I did a aptitude full-upgrade and let it update menu.lst (did a diff first and it looked good).

• Preventing endless forwarding with two routers

  - by jarmund

  The network in quesiton looks basically like this: /----Inet1 / H1---[111.0/24]---GW1---[99.0/24] \----GW2-----Inet2 Device explaination H1: Host with IP 192.168.111.47 GW1: Linux box with IPs 192.168.111.1 and 192.168.99.2, as well as its own route to the internet. GW2: Generic wireless router with IP 192.168.99.1 and its own route to the internet. Inet1 & Inet2: Two possible routes to the internet In short: H has more than one possible route to the internet. H is supposed to only access the internet via GW2 when that link is up, so GW1 has some policy based routing special just for H1: ip rule add from 192.168.111.47 table 991 ip route add default via 192.168.99.1 table 991 While this works as long as GW2 has a direct link to the internet, the problem occurs when that link is down. What then happens is that GW2 forwards the packet back to GW1, which again forwards back to GW2, creating an endless loop of TCP-pingpong. The preferred result would be that the packet was just dropped. Is there something that can be done with iptables on GW1 to prevent this? Basically, an iptables-friendly version of "If packet comes from GW2, but originated from H1, drop it" Note1: It is preferable not to change anything on GW2. Note2: H1 needs to be able to talk to both GW1 and GW2, and vice versa, but only GW2 should lead to the internet TLDR; H1 should only be allowed internet access via GW2, but still needs to be able to talk to both GW1 and GW2. EDIT: The interfaces for GW1 are br0.105 for the '99' network, and br0.111 for the '111' network. The sollution may or may not be obnoxiously simple, but i have not been able to produce the proper iptables syntax myself, so help would be most appreciated. PS: This is a follow-up question from this question

• Soundtest works, but no other sounds and windows starts very slowly

  - by Kristian Kari

  So suddenly all sounds on my computer stopped working expect the sound test works, but when I go to control panel and audio it says there's no audio device. And audio players and audio on website doesn't work either. and Also windows starts very slowly. I'm not sure if this helps but I'll tell what happened before this. I downloaded this program from a little shady website, I hesitated and for a good reason I guess cos the moment I finished downloading it, my antivir detected it as unwanted program and put it on quarantine. I thought everything was fine, but had some problems with program (won't go to details about it cos it's not really related to audio) so rebooted the computer and I was suprised that windows started really really slowly. It took like 5 mins to load the desktop such. After that I noticed the sounds were missing, I immediately deleted the program since I thought it was causing the problem. But it didn't change much. I tried to find the solution with no success and now I'm just scanning again my computer. I'd be thankful if anyone would be able to help me. I might have left a thing or ten things out, so feel free to ask. oh and I'm using windows xp

• Computer won't start after installing new video card

  - by Vercas

  So, 1 year and 340 days ago I bought a desktop computer. Since then, it has served me well. But lately, I wanted an upgrade, so I bought a new video card. I documented myself about the compatibility, and it is okay. So I opened the case, cleaned up that... dust elemental living inside of it. Unscrewed the plastic thingie on the outside to unscrew the old video card. Because of the stupid arrangement of the ports, I had to unscrew the motherboard to unplug it. So I unscrewed it, removed the old card, put in the new one, moved the motherboard back, screwed it back in, screwed the video card on the holder... thingie, and screwed the plastic thingie back in. Everything went smoothly, nothing had to be forced in/out. I connected the external power supply, closed the computer case, put the tower back in it's place and all the cables back in. When I pressed the power button, the LED turned... some color I can't distinguish. It stayed that way for a second, and then it went off. I tried a bunch of things, including permuting the external power supply arrangement (1 connection, 2 connections and no connections), with no success. And here are some of the specifications: Motherboard manufacturer: Asrock Processor: AMD Athlon II X2 3.0 GHz RAM: 2 x 2GB (had only 1 initially, bought the second plate a bit later) OLD video card: AMD Radeon HD 5450 NEW video card: Gigabyte nVidia GeForce GTX 650 GPU, 1GB GDDR5 128bit PCI-E, Dual-link DVI-Dx2 / HDMI / D-Sub Power supply: 450W + all the requirements I managed to find on the internet are met (+12V 18A or something) More specific information is stored... On that computer. If required, I may open the case again and read the stickers to find more specific information. I can also provide photos if necessary. Any ideas? Suggestions? Something? :|

• Can't install Hyper-V in Windows 8 Pro. Causes boot loop, pain & suffering

  - by Nick

  Hardware: Intel i7 2600K (not overclocked, SLAT compatible, virt. features enabled in bios) Asus Maximus IV Extreme-Z (Z68) 16Gb RAM 256Gb SSD Other non-trivial working parts Adding Hyper-V is causing a boot loop resulting in an attempt at automatic repair by Windows 8 after the second or third loop: I'm trying to get the Windows Phone 8 SDK installed and I've narrowed down my troubles to the Hyper-V feature in Win8. This is required to run the WP8 emulator and there are no install options to omit this feature. My first attempt completely borked the OS as I did not have a recent restore point or system image, so I did a completely clean install and made plenty of backups/restore points. I skipped the SDK install and went straight for the windows feature add-on for Hyper-V. This confirmed that Hyper-V is the issue as the same behavior resulted. I cannot find any hint in the Event Logs. Cancelling automatic recovery causes the same behavior to repeat. I don't have any other VM products installed. My only recourse is to use a restore point, try something else, install it again, and see what happens. No luck so far. I'm on my 10th attempt here. Any help would be much appreciated.

• How to speed up request/response to django using apache or another solution?

  - by jbcurtin

  Hey all, I'm mainly a developer, but every now and again I jump into the sys-admin position. For the most part I've gotten away with deploying php and python apps using apache. I write today because I'm starting to research faster alternatives to apache, yet still have some of the core features I require like put and delete methods and the ability to connect to a socket via apache. ( This I have not tried, but might be a nice whistle if I ever employ comet on my apps. ) As you've probably guessed, I use javascript exclusively for all my websites utilizing deep linking for SEO support. The main areas that I'm looking to increase performance is the connection between the django apps and the web server to the client response. Every day I work my best to keep the smallest memory foot print as possible, however I am getting to the end of my rope when it comes to working with apache. In general, keep in mind that I'm just starting this research so I'm looking more for material to read then solutions at this moment. My main questions: Am I missing something about apache that makes it faster then everything else? What would be a good server environment to deploy just static files one? What are some of the leading open-source and paid alternatives?

• WAN Optimization for Small Office/Home Office

  - by TiernanO

  I have been reading up on WAN optimization for the last while, mostly out of interest of speeding up my own internet connections, but also to speed up the office internet connection. At home, I have 2 cable modems plugged into a RouterBoard RB750, which load balances the connections. In the office, we have a single connection into a NetGear router. Most of the WAN Optimization products I have seen, seem to be prohibitively expensive, but also seem to be based on the idea of having multiple branches around the world. What I am looking for, ideally, is as follows: software install: I am "guessing" I need to install it in 2 places: one in the office or house, and one in "the cloud". any connections going to, say, The US (we are in Europe, but our backup's live in the US currently, which would be something important to speed up) would be "tunnelled" though the Optimizer. If downloading or uploading large files, open multiple connections between both "the cloud" and the optimizer... This is where a lot of speed could be gained. finally, for items not compressed, they would be compressed on the cloud side of things, also items that are already on the optimizer could be not sent again. kind of like RSync or Proxy servers... So, is there something that can be done? Is it available using off the shelf components (some magic script with SSH, Squid, Linux and duct tape) or is it something that needs to be purchased? or even an Open Source Project that does 90% of what i am asking?

• Windows freezes when watching videos

  - by cornerback84

  I have Acer laptop Aspire 5740 - 5780 with windows 7 Ultimate 32 bit. I am using Chrome. Windows is 1 year old, but it's not the first time this has happened. Windows freezes whenever I am watching videos on facebook/youtube or when using SopCast. I thought there was some faulty plugin, so I recently re-installed chrome but it happened again. No keys work, and the sound of whatever I am listening starts repeating like grrrr..drrrr. Its seems like the sound in very slow motion. One time I left it in this freeze state for 5 min and it recovered automatically. It usually does not happen when I am using windows media player. I had some codecs installed but I removed them to see if that fixes. So far, I have narrowed it down to youtube/footytube videos and sopcast. I have checked event logs but nothing special. Is there any way I can narrow down the problem or any suggestions on how to fix it. I'd like to add that it does not always happen. Sometimes windows goes days/weeks without freezing, and sometimes it take a min into video to freeze.

• How to quickly check if two columns in Excel are equivalent in value?

  - by mindless.panda

  I am interested in taking two columns and getting a quick answer on whether they are equivalent in value or not. Let me show you what I mean: So its trivial to make another column (EQUAL) that does a simple compare for each pair of cells in the two columns. It's also trivial to use conditional formatting on one of the two, checking its value against the other. The problem is both of these methods require scanning the third column or the color of one of the columns. Often I am doing this for columns that are very, very long, and visual verification would take too long and neither do I trust my eyes. I could use a pivot table to summarize the EQUAL column and see if any FALSE entries occur. I could also enable filtering and click on the filter on EQUAL and see what entries are shown. Again, all of these methods are time consuming for what seems to be such a simple computational task. What I'm interested in finding out is if there is a single cell formula that answers the question. I attempted one above in the screenshot, but clearly it doesn't do what I expected, since A10 does not equal B10. Anyone know of one that works or some other method that accomplishes this?

• Help trying to figure out why IIS7 is crashing / locking up / denying connections

  - by Pure.Krome

  Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

• Login failed for user 'XXX' on the mirrored sql server

  - by hp17

  Hello, We have 4 web servers that host our asp.net (3.5) application. Randomly, we get error messages like : 1) "Login failed for user 'userid'" 2) "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" we are running sql2005 and have a principle and a mirror db (sync). When these exceptions are thrown, I look at the SQL error logs on the mirrored db and noticed the failed login messages in there. The principle db is running fine and the other web apps are working great. this will happen for maybe 10 min, then the app pool recycles and it starts hitting the principle db again. Is there a configuration I have incorrect? my theory is that our principle db is forwarding the request to the mirror, but that should never happen. any help??

• Permission denied (publickey,gssapi-with-mic,password) ssh error

  - by zentenk

  Heads up I'm a noob with linux and networking. I set up a ubuntu server and I have a static ip for my network. When I try to connect to the server at home (external), it prompts me to log in. I supply the correct password (or incorrect pw), I get the error Permission denied, please try again. and after 3 times I get Permission denied (publickey,gssapi-with-mic,password) I am however able to connect with SSH from another computer in the same network with ssh < internal ip of server > I'm connecting with mac os x and my config file is vanilla. Note: During installation of ubuntu it says I don't have a default route or something while doing auto network configuration, but I ignored it and continued the installation, could this be the problem? EDIT: I have tried the below, I have nothing in hosts.allow and also iptables shows the ports that I have allowed, which is 22. I checked the auth.log, and there is nothing when I connect to it remotely (even when it says permission denied). I have tried connecting to it internally and the correct authentication logs show. Any idea whats wrong?

• Old scheduled task still being started, but can't find it.

  - by JvO

  System: Windows XP Home Summary: Some scheduled task is still being started by Windows, but I can't find it, nor determine where its configuration has been stored. This is turning into a mystery for me... I set up a Windows XP Home machine to run a task at 7:00 AM, using the Task manager. This was a clean install, no users defined, so you got straight to the desktop after starting the machine. The filesystem uses NTFS. Later on, I needed to introduce users, so I created one (named Sam) with administrator privileges. After this I noticed that the scheduled task failed, most likely due to privilege errors (i.e. can't write to a network drive). So I want to delete the old task, and add it again with the correct user credentials. However.... I can't find the old task!! I know it is still being executed at 7:00 AM, but there's no mention anywhere on the system of this task. I've looked in c:\windows\tasks for .job files, but there's only the "MP Scheduled Scan.job" from Security Essentials. I've searched the whole disk for mention of the batch file that is being run, but can't find it. So why is this old task still running, and more importantly, why can't I find it? Would it have something to do with introducing users on XP?

• One Windows Domain workstation can ping gateway but gets no internet access

  - by dindeman

  One of the (Windows XP SP3) workstations of our Windows Domain could not access internet anymore, this problem suddenly happened overnight. The domain controllers (there are three of them) are all running Windows Server 2008. First I compared the output of ipconfig /all on the faulty workstation with the output of a working workstation and it was just fine as it had always been. In particular the default gateway was correct and always remained pingable from the faulty workstation. I guessed that something was wrong with the DHCP service and I restarted the DHCP server service on all of our three DCs as well as the DHCP client service on the faulty workstation. This didn't solve the issue. I then thought of renewing the DHCP lease with ipconfig /release and ipconfig /renew and here is my first question: why did this never work? The same IP address (192.168.0.45) kept being assigned despite all my attempts to renew it (note that all our workstation are getting their TCP/IP automatically.) Even by leaving the domain and changing the computer name the same address was yet again obtained... Anyway I then proceeded to switch the TCP/IP configuration for that machine manually to another free valid IP address (192.168.0.41)... and then the internet access came back! I then cleared any traces of the previous IP in the DHCP leases list and in the DNS tables of our DCs and, after setting back the TCP/IP configuration to 'automatic', finally, the new lease would be granted (192.168.0.41) alongside with the internet access. My second question: what went suddenly wrong with the original IP address?

• Dell Vostro Desktop error.

  - by goldenmean

  Faced a strange situation at work today. We have people sitting at a table on opposite sides, with power cables underneath the table. This morning when the person sitting opposite to me banged his feet on ground, it disturbed the power cable to my PC and it turned-off. So when I turned it on, it says, "No boot device found" Press F1 to setup or F5 to perform test... There was no physical impact/crash/fall of the desktop cabinet, which could have crashed/damaged the hard disk physically. EDIT: The OS is Windows 7 So I tried to recognize it in the Bios setup, but even there it could not find the SATA disk that is connected to this machine. So then I opened the cabinet, removed the power supply and plugged it back again. Tried to reboot, same error, "Boot device not found" It is not recognizing the hard disk. Any ideas about what might be wrong? Hard-disk crash, OS Crash(But it doesn't even go to the point of loading the disk after the initial Bios execution, so doubt this...) Any pointers about how I should proceed to troubleshoot/solve this error are welcome.

• Why doesn't NFS recognize a new UID?

  - by user76177

  I have two servers running RHEL6. I have root access to both. The main server, which I will refer to as server, is a database server. The application server, which I will refer to as client, mounts a directory from server via NFS. There is a user, appuser, on both client and server. However, appuser's UID on client is 502. appuser's UID on server is 506. Both users need read and write capability on the NFS share. To facilitate this, I made the share owned by appuser on server. Running id appuser on each yields: uid=506(appuser). Of course, client does not recognize that ownership, since appuser has a different id on client. So I did the following: Changed UID of user in /etc/passwd on client to be 506. Changed ownership of appuser's $HOME on client to be appuser again so that I could log in. Now, when I go to look at the NFS share from the client side, I see that it is owned by 502. 502 is the OLD id for appuser on client. I can't change ownership of the NFS share from client, since that is a volume that physically resides on server. I need to make sure that the NFS share shows ownership of appuser from both server and client. What step have I missed since changing the appuser id on client? NOTE: I have not rebooted client (or anything else.)

• Random server lag, no CPU/mem/pagefile usage

  - by Kev

  We have a fairly new server running Windows 2003 SP2, and the past few days we've noticed random slowdowns. When I'm logged into the server over remote desktop while this is happening, or if I'm physically sitting at the server logged in, suddenly everything becomes extremely laggy. Any UI element I try to interact with takes upwards of ten seconds to react, and then responds very slowly. Then a minute later everything is quite snappy again. During this, I have Task Manager minimized to the tray, and there's no CPU usage. I open it up right after this happens, and there's very little CPU usage on the graph, and no memory or pagefile usage above normal. (Normal being 1.5 GB free in the case of memory.) This is what I see logged into the server, and then users start calling saying things are slow, timing out, and failing--anything to do with our server. No events in the Event Viewer around the times this happens. The context I'm working in (last thing I clicked, etc.) seems different every time--different programs active, different combinations of programs open. Never anything particularly stressful (like adding an event entry to a Cobian Backup configuration, or editing text in TextPad, which has been exceptionally stable in my extensive usage of it.) I would've thought it was just the server, but a family member's home PC (entirely separate) running WinXPSP3 had the same thing happen to it last night a few times. Is this some new behaviour introduced by the latest Windows Updates? Either way, where do I even start to look when nothing seems to be chewing up resources?

• Smart card driven membership and door entry system

  - by Rob G

  I'm looking at putting in a smart card driven system at my local sports club (which doesn't have oodles of money), and since they're willing to pay for hardware, and I'm willing to do the technical setup, I was wondering if anyone had any experience in setting something like this up. Writing any software needed is not the problem, I've pretty much got that covered with various open source projects out there and custom code I'll write, but it's more the hardware side I'm not too sure about and I'm looking for advice from people out there. I'm sure there are numerous complications, but on the surface it looks fairly simple. I'd basically like to enable members to swipe/touch a smart card at the door to gain entry to the club, walk up to a touch screen PC and swipe/touch a card reader there to "login" to the system I create, which will allow them to book club facilities etc. I may even want that same card to then activate things like lights or music when they enter the room they've booked. Pretty Eutopian I know, but still, we'd like to get as close as we can. As I said, the software shouldn't be a problem, and on the hardware side, so far I'm looking at: All in one touch screen PC running Windows 7 or Ubuntu USB card reader (not sure which one to buy) Smart Cards (again, never bought these before) Door/lighting hardware that could be triggered (not sure here either) If anyone has any advice on implementing something like this - especially the items I'm not sure about above, and of course anything I've missed out that's crucial, I'd be most grateful. Recommended hardware that you've used for something like this would be fantastic!

• Ubuntu+Win7--disk error press any key to restart

  - by Siddharth

  Apparently,none of the solutions in any other posts and forums worked for me For some reasons I decided to remove ubuntu from my hard disk drive. My partition table(presently): (/dev/sda1) (fat32) 900 MiB ---(MBR,I suppose) (/dev/sda2) (ntfs) 70 GiB -----(Windows 7) (/dev/sda3) (ntfs) 314.88 GiB --(Personal File storage) (/dev/sda4) (ext4) 80 GiB -----(Ubuntu 13.04) (unallocated) -----1.31 MiB So,after moving(cut-paste) everything(for backup) from the fat32 partition using win7..I booted into Ubuntu and copied the remaining 3 files(hidden in Win7 file explorer) --bootmgr,bootsect.bak,and one more which I do not remember.TERRIBLE MISTAKE After this I again booted into Windows and deleted ext4 partition..formatted it to ntfs..and shut down the pc.Then,I put in a Win7 bootable USB..using command prompt I entered bootrec /fixmbr,and bootrec /fixboot.. Restarting showed me the GRUB..choosing windows 7 showed me "Disk Error. Press any key to restart." I also installed a fresh Win7 installation on the 80 GiB partition expecting a Windows Legacy Bootloader with two win7 options..but did not work. Then..I used a Ubuntu LiveUSB to put it back to the present configuration(above) since all methods to restore the MBR failed.. I copied back the fat32 partitions backup files but couldn't copy those 3 files.Somehow ,they had been recreated and were non-replaceable. I do not want to format the win7 partition for a fresh one. I have used boot-repair..Restore MBR option brings back to "Disk error...." without even going through grub..so I reinstalled grub and I'm able to boot into Ubuntu. grub menu shows the win7 option as "Windows 7 (loader) (on /dev/sda1)". paste.ubuntu.com/5753710 paste.ubuntu.com/5775999

• Microsoft Office 2003 applications crash on 'Save As' to a network mapped drive

  - by Archit Baweja

  Hey guys, so I'm not sure if it belongs on ServerFault forums so figured I'd ask here first because its a workstation/client side issue. I have a client where we have windows server 2003 setup, with windows xp professional setup on all the workstations. We've setup a 'domain' and all workstations logon to the domain (authenticated by the Windows Domain Controller), and in the logon script we map drives on to each workstation. Everything is working peachy except for one workstation, where when I open a file in excel from a mapped drive, it opens fine, but when I go to hit Save As, the Save As dialog pops and hangs up. I cannot perform any other action in excel. When I try cancel the Save As dialog, excel crashes. The mapped drive opens up fine in Windows Explorer. To further investigate this issue, I created a new blank text document on the network drive in Windows Explorer. I then opened it. Then hit save as, and the Save As dialog opened up fine and it would let me save the document. I repeated the above steps for a word document. However this time the Save As dialog hung/froze again. So I'd imagine its a Microsoft Office Issue. Any ideas?

• Very Slow DSL (ethernet) speed [New Interesting Update]

  - by Abhijit

  Very IMPORTANT and INTERESTING UPDATE: Due to some reason I just thought to do a complete new setup and this time I decided to again have openSUSE plus ubuntu. So I first reinstall lubuntu and then I installed OpenSUSE 12.2 (64 bit). Now, my DSL speed is working very normal and fine on opensuse. So this is very scary. Is it possible for any operating system to manipulate my NIC so that it will work fine only on that operating system and not on another os? Regarding positive thinking and not being paranoid, what is it that makes ONLY suse to get my NIC to work at normal speed but ubuntu can not do it? Not even fedora? Not even linux mint? What all these OS are lacking that enables suse to work great? == ORIGINAL QUESTION == I 'was' on opensuse 12.2 when my dsl speed was normal. Yesterday I switched from opensuse to ubuntu 12.04 and speed decreased. It came to range of 7-10-13-20-25-kbps. Then I switch to linux mint, and then to fedora. Still slow speed. When I was in ubuntu I disabled ipv6 but still no luck. Now I am in fedora but this time with DIFFERENT ISP. And still I am getting very slow sped. So my guess is this is nothing to do with os. What can be wrong? Is this problem of NIC? Does NIC speed decreases over time? Does NIC life ends over time as with keyboard or mouse? Help please All the os I used are 64 bit and my laptop is Compaq Presario A965Tu Intel Centrino DUal Core. Interesting thing to notice is I get normal speed while downloading torrent inside torrent client softwares. This slow speed issue applied to download from any web browser or installing software using terminal.
