• Solid State Drive Occasionally Freezes For A Minute While OS Is "Beach Balling"

  - by Boris_yo

  Almost a month ago I bought Intel 330 128GB solid state drive, migrated my data with Intel branded limited-feature Acronis from old HDD to new SSD, optimized with Intel Toolbox and started using it. Occassionally I get close to 1 minute freezes while seeing operating system "beach balls" and animations still work, I can interact and click on something but nothing responds, nothing loads. Recently a couple of such freezes occurred in shorter amount of time in a row. I have noticed that if I stop interacting with laptop, the freeze lasts less time than if I was interacting with laptop. But the bigger problem is when freeze just does not end and computer keeps being stuck unlil it is more than half hour and I run out of patience to keep waiting and feeling I need to restart the system because I am not getting anywhere. Such freeze happened while laptop was cold booting into Windows 7. This is when freeze hang occurred and I had to restart, only later to be greeted with Windows recovery screen stating something about faiure of boot sector and asking to insert Windows repair CD. But after I restarted, Windows booted successfully and all was well. I have filmed video of freeze hang occurring in cold boot which you can see here (on video page look below for description): http://www.youtube.com/watch?v=8b7MQlcDTUs As I have mentioned in the beginning, the SSD is less than a month old but here is S.M.A.R.T statistics just in case (TRIM is enabled btw according to CrystalDiskInfo): I want to emphasize that this SSD is the only drive I have, yet it is working in RAID mode (it was enabled initially in BIOS by previous laptop's owner) on Intel Rapid Storage drivers. I am contemplating about switching to AHCI mode but want to be sure this won't cause data loss. Additionally, the stock firmware is the only firmware available currently, yet Intel does not respond to my posts in their community board. If anyone here has this SSD model or generally has experience with SSD drives, I would love to know your thoughts.

• trouble shooting ntfs-loop-xen combination in wubi based grub of Ubuntu

  - by Registered User

  Here is a situation I installed Ubuntu on a laptop using Wubi in Windows 7 drive.*The laptop is not mine.*I have installed and things worked by now perfectly without any problem.We are trying to set up a Xen (virtualization)environment in this laptop. After setting up every thing cleanly.When I needed to boot with following grub entries menuentry "Xen Linux 2.6.32.27" { insmod ntfs set root='(hd0,2)' loopback loop0 /ubuntu/disks/root.disk set root=(loop0) multiboot /boot/xen.gz module /boot/vmlinuz-2.6.32.27 dummy=dummy root=/dev/sda2 loop=/ubuntu/disks/root.disk ro console=tty0 module /boot/initrd.img-2.6.32.27 } I got error file not found error unknown command 'multiboot' error unknown command 'module' error unknown command 'module' Now to dig this issue further I reboot the machine and go to grub command prompt and manually pass on each of the above parameters which you see in the grub entry when I reached grub> insmod multiboot then I got following message on screen error:file not found. It looks like this wubi+ grub setup has just enough modules to use loopback file on ntfs, but the ACTUAL /boot directory is on the loopback NOT ntfs (hd0,2). Therefore any attempt to read any files from (hd0,2) simply wont work, cause there's no file there.I need to use insmod multiboot and command multiboot and module which are available in grub on a normal install without Wubi.But since the laptop is not mine so I am not allowed to partition it and have to make it work in this situation only. While a normal Kernel is still booting? How can I get module multiboot in this Wubi based install.

• The Wifi is working fine but no internet connection in Windows 8 [migrated]

  - by Ali

  I'm currently having a Problem with my msi GT70 laptop. my laptop is running windows 8 and yesterday it requested a Restart to Update. after the Restart and the update I tried to surf the net through google chrome, the WiFi connection is perfect but the page I tried to access is not loading at all, after a while it shows failure to load page. I disabled and reenabled the WiFi chip through the device manager but still no internet connection. I uninstalled and reinstalled the drivers, still no internet. I updated the Driver of the wifi, still no internet, I even went to Wifi configuration and tried to change the DNS and reset it back to automatically, still no Luck.. I'm really lost I don't know what to do, I don't want to go deep and play with Laptop DNA "aka: registry file" and screw things up. I really appreciate any help in this matter. thanks in advance. Note: I tried to access many pages but no luck. I even tried Firefox, Opera, even ie still no luck. The internet is working fine on my tablet and cellphone, except for the Laptop.

• Resolving loss of internet bandwidth in home network

  - by Caspar

  Recently, I've decided to connect my laptop at home to my modem/router through Ethernet cables built into my apartment. As these built-in Ethernet cables are usable via plugs built into the walls (called powerline adapters), I use some additional cabling (STP CAT6 cables) from my laptop/router to the plugs. In addition, I don't know any technical details about these built-in cables (as they're not visible), only the maximal bandwidth (1 GBit = Cat6?) that they're supporting. The built-in cables are Cat. 5e Ethernet cables. The problem is now that when I set up the connection, I cannot use the full bandwidth that my internet connection is actually offering (100 Mbit/s), only about 85 Mbit/s between 85 - 88 Mbit/s, despite the fact that all cables involved should support the maximal bandwidth. I know from other tests with one of the Ethernet cables in use that I can use almost 99 Mbit/s when I connect my laptop directly to the router/modem using only this one cable. In addition, it is very unlikely that the length of the resulting cable connection from my laptop to my router involving the built-in cables exceeds 100 m. So, what possible reasons for this loss of bandwidth exist? And how I can fix this issue? I hope this might help resolve the issue: The built-in cables appear to be Cat. 5e Ethernet cables. So, is there any problem when I connect Cat6 Ethernet cables directly to Cat5e Ethernet cables via the plugs?

• Docking Station Sound Doesn't Work on Dell D830 with Windows 7

  - by cisellis

  I have a Dell Latitude D830 laptop that is running Windows 7 Enterprise x64. I connect to a docking station during the day with multiple monitors, a keyboard and a mouse. Everything runs with no problems including most of the docking station ports (usb, monitors, etc.) However, the sound port from the docking station does not work since the upgrade to Windows-7. Even with the laptop plugged in, the sound always comes out of the laptop, not the headphones plugged into the docking station. Here's what I've tried: I've seen other issues like via Google this that seem to be mostly unanswered. I found one or two that referenced using the Vista x64 drivers, especially the Nvidia drivers. I do not have an Nvidia chipset but I've reinstalled the sound drivers and that has not helped. I don't have a support contract and considering the cost is usually high to call Dell, that's not an option. Dell's forums are pretty much a wasteland and I've found no help there. Since this is a docking station I thought I might need to try the SATA or Intel chipset drivers from the dell site instead, however I'm not really sure and I need to work on this laptop in the meantime. I can't really afford the downtime to experiment with random drivers all day in case they turn out to be incompatible (Dell still hasn't added Windows 7 to their support site as far as I can tell). Does anyone have any other ideas? Has anyone had this issue and solved it? If so, how? Thanks in advance for your help.

• Wake on LAN Problem

  - by Caley Woods

  I'm working to get wake on lan (wol) working so that we can do some power management at my workplace. I've enabled WOL on a test laptop running Win 7 x64 and put it to sleep and hibernate both with no luck. I'm using a 3rd party utility and I've ran wireshark on the test laptop with it booted up and I can see the WOL packets coming in and the machine refuses to wake from sleep or hibernate. I thought maybe it was the computer I was using so I had another Win 7 x64 laptop nearby and I tried it, same scenario. We're in a cisco environment and I believe I gotten all the pieces in place since I'm seeing the WOL packets come through. I've tested two machines on the same subnet to eliminate the possibility of a misconfiguration on the switch, this also has the same behavior. The laptop models are a Compaq 6510b and 6730b. Is there something I'm missing? I'm trying this across UDP port 50200 since that's the port the actual management system will use after I get it working.

• Administrative shares in Windows 7 Pro not visible

  - by Chris Tybur

  My desktop machine has a clean install of Windows 7 Professional. For some reason the standard administrative shares Admin$, C$, D$, etc are not visible, either in Computer Management - Shared Folders - Shares or via net share. I also have a laptop with a clean install of Windows 7 Professional, and I can see the admin shares in both places. As such, I can map to \\laptop\c$ from the desktop, but I can't map to \\desktop\c$ from the laptop. I pretty much took the defaults during the Windows 7 installations. I've tried adding LocalAccountTokenFilterPolicy to the registry on the desktop, but that didn't work. On the desktop I've also disabled UAC, turned off Windows firewall, removed it from a homegroup, made sure file and printer sharing is turned on, but nothing has worked. There is some subtle difference between the two machines that I can't seem to find. I'm logging into both machines using a local account that is in the Administrators group. Both accounts have the same name and password. I really don't want to have to create a new share for the desktop's C drive, especially since C$ is visible and working on the laptop and therefore I should be able to make it work on the desktop. Any idea why the admin shares would work on one machine and not another? Or why LocalAccountTokenFilterPolicy would fail?

• ACER ASPIRE V3-571G-9435 Fan not kicking in leading to overclocking

  - by brythespy

  This laptop has always had this problem. The temperatures kick up to the thermal ceiling of 99C for the CPU (i7-3610QM) and 94C for the GPU (GT 640M). Problem is, the FAN doesn't give a damn. It's actually QUIETER when the temperatures are that high, than when it's at 60C or so. I figured it was a problem with the BIOS, so I updated that, no change. So maybe it was a problem with windows? Nope, same result on gaming with Ubuntu. The major problem of this, is that after gaming for ten minutes the CPU throttles itself to 1197MHz(as opposed to 3193), and the GPU goes down to 135MHz( as opposed to 843MHz). The problem is that the fan won't kick in like I know it can, because when the laptop is in POST, like at BIOS setup, the fan is like a vacuum cleaner it's so loud! I don't really care about noise, so I'd love to have the fan like that all the time as long as the temperatures don't fly through the roof... So, things I've tried so far, to avoid possible duplicate answers. Checked for dust: It's been this way since the laptop was new, and I've since then taken it apart. No dust buildup. Background stuff running?: No, problem persists across OS'es, and it happens while gaming anyways Manually underclocking both CPU/GPU: Using windows, I can force the CPU to stay at 1.1GHz, but the temperature STILL easily hits 99C after 5 min of gaming Contacted Acer support?: No help at all. They told me to update and reset the BIOS, which I have done multiple times. There are only about 6 changeable things anyway, none of which should affect the FAN control Third party fan control program?: None detect the fan So, I'm screwed until I can afford to replace this laptop, but I am very satisfied with performance in games... Whenever the CPU/GPU aren't being throttled. Anyone that can offer advice to solve this problem would be greatly appreciated. Hell, if you solved my problem I'd send you some monies through paypal.

• USB Harddisk not working on dual boot windows7/8

  - by Jesper

  Yesterday I installed Windows 8 on a machine that already had Windows 7. They are on dual boot and both systems work fine. The problem is that inserting a USB hard disk in either system does nothing. If I connect a USB mouse or mobile phone, they work fine, so the USB plugs are active/working and the USB hard drives that I am trying to connect work on my other laptop just fine. I have tried to uninstall all USB-related items in Device Manager and let them reinstall upon restart, but that didn't help. The USB drive does not show up in disk management either. The strange thing is that it is exactly the same situation on both windows. USB mice etc. work just fine and USB hard drives do not. Any ideas on solving this problem would be great. ...Don't know if it is important, but this is a Toshiba Tecra R950 Laptop. EDIT: I have found out that my other USB HD (Western Digital) works on this laptop, but for my StoreJet Transcend and Adata "something" does not work. All three work on another Windows 7 laptop. Sizewise the WD is in the middle at 400 GB. The StoreJet is 640 GB and the Adata is 200 GB.

• Offline productivity

  - by Frank Meulenaar

  On some days I'm commuting 2hs (oneway) in the train. I don't have any mobile internet nor is there always WiFi service in the train. Because of security reasons I can't do any work in the train so I'm trying to work on my geek time. I'm looking for general solutions on how to do this (I'm on FireFox/Windows but I don't think it matters) Email works perfectly with gmail offline. It syncs directly when online and remembers complicated stuff. So far I used the ScrapBook plugin to store an website. It works good, but I have to download my favorite news page every day again - I want it to sync as soon as possible. It would even be more awesome if I could click a page on my desktop and my laptop would sync as soon as it has the chance. (edit: maybe the autosave plugin for scrapbook can do this) Similarily, I use the Downloadhelper plugin to download youtube vids, but I'd like something that automatically downloads videos from a given channel. Any tips are welcome. So far my early morning schedule is: wake up, power on laptop, make coffee, power off laptop and leave within 10 minutes (enough time for GMail to sync) but I can imagine a system where my laptop stays on during the night (or boots before I wake (and makes me coffee :])).

• NumLock is so weired in Ubuntu

  - by ???

  The NumLock and the keypad is so weired in Ubuntu. I have two computers, A is a desktop, with USB keyboard, B is a laptop, with laptop keyboard and another USB keyboard. On the desktop A, whether the NumLock is on or off, the number keys on the keypad just don't work. Also the NumLock LED is always off.

• Forward all traffic from one IP to another Ip on OS X

  - by Josh

  This is related to this question I just asked... I have two IP address on my iMac I want to "bridge". I'm not sure what the proper terminology is... here's the situation. My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface. If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command. Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

• Docking Station Sound Doesn't Work on Dell D830 with Windows 7

  - by cisellis

  EDIT: I can only mark one answer as the correct one but the actual solution was a combination of two comments (updating the BIOS to A15 AND installing the Sigmatel audio drivers). I have a Dell Latitude D830 laptop that is running Windows 7 Enterprise x64. I connect to a docking station during the day with multiple monitors, a keyboard and a mouse.

• NTFS 'Owner' missing when accessing hard disk from external USB adapter

  - by trismarck

  I have a hard drive with Windows XP SP3 installed on it. When the drive is connected through the standard SATA connector inside the laptop, everything works as expected. However when I remove the drive from the laptop and connect the drive to the external USB adapter, almost all files / folders lose the 'Owner' field contents. I was wondering why could that be. I've tried two USB adapters and this happens on each. I could take the ownership of all of the files, but this would overwrite the Owner value (the Owner value that is present when the drive is accessed through standard SATA connector in the laptop). //edit: if the hard drive is used through the USB adapter, I can't access most of the files, at least until I take ownership of the files (/folders). This is how it looks like: HDD inside USB adapter: HDD inside laptop: (note the Owner column) //edit: some of the files on the first screenshot have Owner field filled up. That's because I took the ownership of those files / folders to be able to access the files on the hard drive. //edit2: also, if the hard drive is connected through USB adapter and if I've took the ownership of some files by the 'ddd' user, then if i login as a different user (lets say 'eee' user), the owner field is _still_ empty: ddd user: eee user: eee user can't access the 'ddd' folder. Both users have Administrator priviledges.

• "Ethernet" doesn't have a valid IP configuration

  - by Xuzuno

  I'm using an ethernet cord to connect to my internet and it has been working well until Thursday morning when I turned on my laptop (Windows 8) to see a yellow triangle sign in the bottom right hand corner, in front of the ethernet connected symbol. Since then I haven't been able been able to access the internet from my computer. When I hover over it, it says that it is an "Unidentified network" and there is "No internet access". I've run the Windows 8 troubleshooting and it says that the problem found was ""Ethernet" doesn't have a valid IP configuration", but I'm unsure how to fix it. I'm thinking that the problem is to do with my computer rather than my network, because I've tried another laptop (Windows 7) through the same ethernet cable and connection and the internet works fine on the other laptop. I've tried so many fixes that I've found online, with none of them actually working. Yesterday I even tried a full system reset, where I re-installed Windows 8, re-partitioned and wiped everything off the hard drive, but it still appears have the exact same problem. Today I also purchased and tried a new ethernet cable which didn't work, so I then purchased a USB to Ethernet adapter, to make sure that it wasn't my ethernet port on my laptop that was faulty. That didn't work either, and the same problem still remains. I feel like I've tried everything, so can someone please help me?

• Why does my computer sometimes not identify my wireless network, or others, that it always connects to?

  - by Emile Erasmus

  I have a vista operating system. Sometimes my computer will not connect to the wireless network (internet) when I start up my laptop. This happens at different places on occasion, and it is very random. It tries to connect, but can not identify the network (it does recognize the wifi name). So at the end it connects, but with limited connectivity. It can not be the hardware because all other computers connect to it fine at the same time. And it happens at different places, mostly home, but sometimes at coffee shops, etc. And then in a day or two when I start up my laptop it is all of a sudden working again. (restart does not solve the problem). I have tried all the trouble shooting options windows offers, restarting the notebook, switch modem on and off, switch laptop wifi on and of, deleted the wifi memory from the laptop and reconnected with the password as if it was the first time, everything. If it does not work at one place it does not mean it won't work at another. Example it won't work at home, then I go to coffee shop and it works, then get back home and it don't. Anyone encountered this before?

• Motorola Surfboard SB6121 modem conected to 2WIREi38HG wireless router but there's no internet access

  - by Jessica

  I have just switched to Comcast cable internet from AT&T Uverse and I was hoping to use the 2WIRE wireless router with the new Surfboard modem so I can have wireless access. I messed around with some settings and got it working for my laptop (I'm not terribly well versed in computer stuff; I think it was mostly luck) for about a week. The other day I tried to get online and there was no internet connection. I restarted the equipment with no success and then plugged the modem directly into the laptop. This worked, so I knew there was no outage. I connected the ethernet cord to the router and a second cord to my laptop and that worked, too. But when I tried again just with the wireless the laptop connects to the router, but doesn't recognize it or find an internet connection. I tried to go to http://gateway.2Wire.net to fiddle with the settings, but all I get is a Server Not Found page. I tried to check the ip address but this is really kind of over my head and I get different things checking it while plugged into only the modem vs when I plug into the router. Can anyone help? The frustrating thing is that I had it working for awhile, so I know it can do it!

• Which RAM is faster (or, is Crucial's Memory Advisor giving non-optimal advice)?

  - by adpe

  In general, if a PC's motherboard is only specified for RAM up to a given core speed x, will that PC be faster with: RAM of latency y capable of running at a maximum core speed >x or RAM of latency <y capable of running at a maximum core speed of exactly x ? I would have thought the latter, but Crucial's Memory Adviser tool advises the former. So, which of us is correct - me, or the machine? (Here is a concrete example: I wish to upgrade a Toshiba Satellite Pro L300-155 laptop from its current 1GB RAM to 2GB Crucial RAM. The laptop's specifications are given here. I see from those specifications that the laptop is designed for DDR2-667 Ram. Crucial sells two compatible 2GB kits, priced exactly the same as each other: DDR2-667, CL=5; DDR2-800, CL=6. It seems to me that of these two upgrade kits, the first kit would run slightly faster on the L300-155 than the second, because both will presumably be capped at DDR2-667 core speed (see laptop specs), but the second kit has more latency. However, Crucial's Memory Advisor tool recommends the second kit.)

• Sudden "No Signal" in HDMI-DVI connection

  - by nazikus

  Yesterday I have connected external display Asus VW192C to my laptop Dell XPS 14-L421X via HDMI-to-DVI-D cable. And it worked perfectly fine from start. The day after, Asus screen went blank showing "No signal". Every time I connection/disconnection cable or power off/on the display it says "No signal". And I didn't change any system configurations meanwhile. To troubleshoot the problem, I have tried to connect laptop to TV (hdmi-to-hdmi) - it was fine. I've tried to connect a different laptop to the display via the same cable - worked fine as well. So its obviously something on system level, either Windows or graphics drivers. Also it seems that Windows still see the external display (I can move mouse pointer away from the main screen in Extended mode), but there's just no signal. Any ideas? What else to try? PS. My laptop has 2 graphics cards - GeForce 630M and Intel HD 4000 using NVidia Optimus technology. I have updated to latest Intel and NVidia drivers, still didn't help. PPS. Although I shouldn't have updated (from Intel support): "our Intel generic graphics drivers from the Intel website do not support using both Intel Graphics 4000 and NVidia GeForece GT630M". Nevertheless, it should not affect connectivity to additional display.

• Printer deployment via Group Policy not working on a single system

  - by Aron Rotteveel

  One of my coworkers just got a new laptop running Windows 7 Pro x64. We use a GPO to deploy the printers to every system, but for some reason it is not working on this system. I have been breaking my head over this for the past 3 hours now without any result. The strange thing is that gpresult /H seems to indicate that the GPO did run. The hardware: Laptop: Windows 7 Professional x64 Print server: Windows Server 2008 x64 R1 HP Color LaserJet 2605dn HP LaserJet P2015 Driver packages on server: HP universal printer driver PCL5, both X86 as X64 Oddities and other info: GPO working flawlessly on every other system, including my own Windows 7 Ultimate X64 laptop gpresult /H shows the GPO being ran Windows Firewall completely disabled on the new laptop Below is the output for gpresult /H (in Dutch sadly, but I think you'll recognize it): Beleidsregels Windows-instellingen Printerverbindingen Pad Dominerend groepsbeleidsobject \\Server2008\HP Color LaserJet 2605dn Printers \\Server2008\HP LaserJet P2015 Printers Beheersjablonen Beleidsdefinities (ADMX-bestanden) opgehaald van de lokale computer. Configuratiescherm/Printers Beleid Instelling Dominerend groepsbeleidsobject Beperkingen van point-and-print Uitgeschakeld Printers Like I said, I have been trying to figure this out for the past few hours or so without any result, so you are my last hope. Any help is appreciated.

• How to use git to manage one codebase but have different environments

  - by emostar

  I'm using git for a personal project at the moment and have run into a problem of having one codebase for two different environments and was wondering what the cleanest way to use git would be. Main Desktop I Use this machine for most of my development. I have a git repository here that I cloned off of an empty repository that I use on my internal server. I do most of my work here and push back to the internal server so I can use that as a master of truth and to ease making backups. Laptop I sometimes want to code on the road, so I did a clone from the internal server and created a new branch called "laptop-branch". Unfortunately some directories MSVC++ version are different than from the Main Desktop environment. I just modified the files in the "laptop-branch" and committed them there. Now I did a lot of changes while on vacation with my laptop, and want to push them to origin, but don't want the changes I made that were related to directories and compiler versions to be pushed back to origin. What would be the best way to get this done?

• Cheated!! Please help

  - by Rohit K

  I was experiencing some hard disk problem with my HP laptop. It showed at bootup as system diagnostics are run -- Smart Drive attribute failed. Also i repeatedly got a warning for imminent hard drive failure and thus to back up my data. So i gave my laptop to authorized HP service center for repair. They formatted my hard disk and installed a pirated copy of Win 7 Ultimate (i earlier had genuine Win 7 Home Premium running on my laptop) and they told me they cover out-of-warranty issues and even charged me for it. What's worse is that the hard drive problem is still present and all i am left with is an illegal copy of windows which i think also voids my warranty. What should i do? I mean i did purchase a genuine Windows with my laptop, so there must be some way to reinstall it even when i don't have a genuine copy now on my machine. Can't i get legit keys to reinstall Win 7 from Microsoft because i did pay for the software when i purchased my machine. And if that's not possible, how can i claim warranty and get my hard disk replaced by HP?

• Variable host IP address in iptables rule

  - by DrakeES

  I am running CentOS 6.4 with OpenVZ on my laptop. In order to provide Internet access for the VEs I have to apply the following rule on the laptop: iptables -t nat -A POSTROUTING -j SNAT --to-source <LAPTOP_IP> It works fine. However, I have to work in different places - office, home, partner's office etc. The IP of my laptop is different in those places, so have to alter the rule above each time I change place. I have created a workaround which basically determines the IP and applies the rule: #!/bin/bash IP=$(ifconfig | awk -F':' '/inet addr/&&!/127.0.0.1/{split($2,_," ");print _[1]}') iptables -t nat -A POSTROUTING -j SNAT --to-source $IP The workaround above works. I only still have to execute it manually. Perhaps I could make it a hook executing whenever my laptop obtains an IP address from DHCP - how can I do that? Also, I am just wondering if there is an elegant way of getting it done in the first place - iptables? Maybe there is a syntax allowing to specify "current hardware ip addres" in the rule?

• Cannot connect to a shared network drive

  - by dublintech

  I am using windows 7, I cannot connect to a shared network drive on another machine. I can ping the machine. I can remote desktop connect to the machine. The machine is on the same subnet My friend with the exact same laptop as me (and on the same network, same workgroup) can connect to the shared folder. The machine I am trying to connect to and my friends machine can both see shared folders on my machine. I also cannot see shared folders on the friends laptop. When I select diagnose, windows tells me nothing useful. When I select see details on the error pop up, I see: Error code: 0x80004005 (google doesn't help much) I can nbtstat -a the machine who has the shared folder. When I try with my firewall turned off the same happens. I have ensured my windows 7 has all updates. I run security essentials to ensure my laptop is clean. I run ccleaner to clean up my registry. Same error. I have tried with my laptop on both wireless and ethernet. As you can imagine, I am banging my head against the wall on this one.
