• Can't log in using second domain controller when first DC is unreachable

  - by rbeier

  Hi, We're a small web development company. Our domain has two DCs: a main one (BEEHIVE, 192.168.3.20) in the datacenter and a second one (SPHERE2, 10.0.66.19) in the office. The office is connected to the datacenter via a VPN. We recently had a brief network outage in the office. During this outage, we weren't able to access the domain from our office machines. I had hoped that they would fail over to the DC in the office, but that didn't happen. So I'm trying to figure out why. I'm not an expert on Active Directory so maybe I'm missing something obvious. Both domain controllers are running a DNS server. Each office workstation is configured to use the datacenter DC as its primary DNS server, and the office DC as its secondary: DNS Servers . . . . . . . . . . . : 192.168.3.20 10.0.66.19 Both DNS servers are working, and both domain controllers are working (at least, I can connect to them both using AD Users + Computers). Here are the SRV records that point to the domain controllers (I've changed the domain name but I've left the rest alone): C:\nslookup Default Server: beehive.ourcorp.com Address: 192.168.3.20 set type=srv _ldap._tcp.ourcorp.com Server: beehive.ourcorp.com Address: 192.168.3.20 _ldap._tcp.ourcorp.com SRV service location: priority = 0 weight = 100 port = 389 svr hostname = beehive.ourcorp.com _ldap._tcp.ourcorp.com SRV service location: priority = 0 weight = 100 port = 389 svr hostname = sphere2.ourcorp.com beehive.ourcorp.com internet address = 192.168.3.20 sphere2.ourcorp.com internet address = 10.0.66.19 Does anyone have any ideas? Thanks, Richard

• Trying to delete directory with "rm -rf", but get message that it's not empty

  - by Ben Hocking

  I've tried deleting a directory using "rm -rf" and I'm getting the message "Directory not empty": Bens-MacBook-Pro:please benjaminhocking$ ls -lart empty_directory/ total 16 drwxr-xr-x 5 benjaminhocking staff 170 Aug 27 14:46 . drwxr-xr-x 3 benjaminhocking staff 102 Aug 27 15:28 .. Bens-MacBook-Pro:please benjaminhocking$ rm -rf empty_directory/ rm: empty_directory/: Directory not empty Bens-MacBook-Pro:please benjaminhocking$ rmdir empty_directory/ rmdir: empty_directory/: Directory not empty If I try the same thing using Finder (dragging the folder to the Trash), I get the message The operation can’t be completed because the item “empty_directory” is in use. I've tried doing xattr -d com.apple.quarantine, purely out of superstition, but it did no good. A probably important piece of context is that this directory was initially in a directory that should've been deleted by a "make clean" command I issued prior to Terminal locking up on me, after which a little over half of the other programs I had running also locked up, including Skype, and eventually the OS itself. I ended up having to reboot the computer by pressing and holding the power key. Edit to add: Another important piece of information I left off was that this was happening in an encrypted folder à la encfs. I was able to track down the corresponding folder in the encrypted side of things and delete it there. I still don't know why I couldn't do it from the decrypted side of things like I normally do. I'll leave this unanswered for now in case anyone has a good answer for that.

• Group policy not applying to security group

  - by ihavenoideawhatimdoing

  Preface: I have enough privileges to create GPOs in my OU, and have made a few of them for some simple tasks (like deploying a printer to certain users). Not actually a sysadmin...I'm a developer who is winging it. I wanted to create a GPO that would set a mapped folder for a certain security group (which I recently created and that contains only myself). Did the following: Created the GPO in MyOU - Users Removed the default Authenticted Users under Security Filtering Add the security group with my account to Security Filtering Set up the mapping via the User Configuration option Changed GPO Status to "Computer configuration settings disabled" Left WMI filtering to Closed the GPO at this point... Logged in as the target user; ran gpupdate /force Logged out, logged in, ran gpresult /r, no mention of my GPO Rebooted Logged in, re-ran gpupdate /force Logged out, logged in, ran gpresult /r, still no mention of my GPO If I log in with another completely different user, their RSOP information shows that the new GPO is being ignored due to a security restriction, so it appears to be "working" for other users. I just can't get it to actually show up in RSOP for the user it should be working. Is there anything else I can do short of rebooting endlessly and crossing my fingers?

• Excael 2007: Name range problems when linking workbooks

  - by Mike

  I've 30+ workbooks each with 5 specific worksheets (formated the same). Each worksheet's data needs to be linked to a master workbook, so that I end up with 5 master workbooks and all the specific data in one long table format $A$2:$I$750. (Are you still with me? ;)) I don't have access to a database, so I'm having to link the sheets to their master workbook directly. I've highlighted the data I need; named the range; and then tried referencing this from my master workbook. I get the #Value error symbol when I try to link (=[WorkbookName]!MyNamedRange) to a cell that doesn't match the top left cell of my range. Example: MyNamedrange is always =$A$2:$I43$ on one specific sheet. On my master workbook it works if it's referenced at A2 but I get #Value if it's referenced A1, or A44. Any ideas? I'm trying to link my data in one continous table so I can run a pivot on it, and other things. Can it be done like this, or should I just copy and paste? I'm trying to keep things 'linked'so I do not need to spend time C&Ping all day. Many thanks Mike.

• Optical Audio out stuck on on a MacBook

  - by Clinton Blackmore

  Apple have made an interesting headphone port for the MacBook (and some other Intel Mac models). It works like a standard jack: nothing plugged in - audio comes out of built-in speakers headphones/external speakers plugged in - plays through headphones/external speakers but you can also use a special adapter (which trips a tiny microswitch) to get an optical audio out signal (which you can presumably plug into a nice surround-sound system). This is all well and good except when, like auto-tracking, it doesn't work, and you are left with nothing to adjust. Users report that they get no sound when they have nothing plugged in and that a red light emanates from the headphone port. If you go to System Preferences - Sound - Output, it will say (IIRC) "Optical Out" instead of "Internal Speakers". The only solution I'm aware of is to try to reset the switch by inserting and removing a set of headphones or a toothpick, perhaps wiggling it inside of the port, and hoping that you luck out and get it. Are there other ways to fix this problem? Does anyone know where the microswitch is or have a good technique to reset it?

• Can I recover a rm -rf-ed Mercurial repository?

  - by WishCow

  I made the mistake of wiping out my entire project directory with a quick "rm -rf project". Of course, the .hg directory went with it. I had about 15-20 changesets, that I have not pushed to anyone, and I would really really like to get those back. The system is a Ubuntu machine, and the partiton where the delete happened is ext3, the project consist mostly of PHP files. I know about the guideline to not write to the disk in question. The first idea was to use the tool named scalpel, to get the PHP files back and diff them with the current version from the repo, and somehow carve the changes out. While it succeeded, it did not recover the file names (or there is a switch I'm missing), so I'm left with a few thousand sequentially named .php files, combing through them is not an option. Can a kind soul please save me, and suggest a way to: a) get the repo back, or b) get the files back, with filenames For those wondering how I did such a stupid thing: I was working on a file in Vim which I wanted to remove from the repository: :!hg rm % This complained that the file is in a subrepository, so I specified the following: :!hg rm % -R engine which complained that file has modifications, use -f to force. And this is when somehow, I made up the following command: :!rm -rf % -R engine Somehow, seeing "force" makes me do a rm -rf by reflex.

• How does one open multiple tabs in TextWrangler?

  - by Closure Cowboy

  No, I'm not bluffing. I really can't figure this out. The setup: I went to File -> Open, and then selected a directory rather than a file. As expected, a directory tree opened on the left side of my document. Hooray! I can easily view the files' structure in my Rails project. So, I make a few changes in a file, and then I click on a different file in the directory tree. My problem: TextWrangler then asks me whether I want to save my changes. Huh? I say "No", and the new document doesn't open at all. Great. I try hitting Command+N (new document). A new window opens. Ughhhh. How the heck do I open documents in a new tab? Note: I have set the "New & opened documents" behavior to "Open in the front window". This does not change the behavior described (i.e. when a directory is opened rather than a single file).

• My New Dell Workstation T-7500 gives electric shock

  - by Dan

  Just bought Dell T-7500 Workstation. When installation technician came to Install the workstation, he got an electric shock when he touched the Start Button. He also got shock when he touched Front Panel. No shock when touching rest of the Chassis. He called Dell Support & tried to troubleshoot by taking out various wires etc but did not help. I touched the same places & I also got shock. We checked everything possible including connecting to various outlets but it didn't solve the problem. Installation subcontractor said that they are not supposed to troubleshoot anything on new system, just install it & they made notes & left. I called my sales guy & it was weekend so he said he will take care of it on Monday. Here are my concerns : (1) Why does that happen ? Although it is a mild shock & it won't kill you but might damage other parts of workstation ? (2) Is this common for workstations ? (3) What should I do ? Of course Dell will try to troubleshoot again but should I let them do that OR ask for a New System ? (4) Wheat would happen if I continue using it till the new system arrives ? Thank You.

• Failing Windows Updates with Error Code 800719e4

  - by Kev

  On a number of Vista machines I have now come across the same error - when installing updates everything works fine, until it after it reboots and the rolls back during step 3. On all occasions (where a simple retry hasn't worked) the error code has been 800719e4. On my own laptop I have so far tried the following:- Installed the updates one by one manually - I started on the smallest and one by one have worked towards the largest one which has left me with "Security Update for Windows (KB2286198)" that refuses to install. Renamed all the files in "C:\Windows\Logs\CBS" to "xxx.old" where xxx was the original name with windows update turned off - no change Renamed all the folders in "C:\Windows\SoftwareDistribution" in the same manner - no change Attempted to install it manually "Windows6.0-KB2286198-x86.msu" - no change Tried to un-install IE8 - doesn't work, rolls back at the end (Installing the IE9 Beta when it launched was what alerted me to the issue on this laptop) Ran a "Fix It" thing from the Microsoft Website - no help (Can't find the link now). Tried to recover from the disk - but alas my laptop only has a recovery partition (and was unservice packed original). Ran with nothing running on startup, and only MS services - again no change. Google is being useless with a load of posts trying to get me to call a telephone number with letters in (presumably an American number) The error code appears to mean error log full but no one has any idea which log! The WinUpdate log does indicate the following is the error point though :- 2010-10-23 13:54:48:230 1240 738 Handler WARNING: Got extended error: "POQ Operation SetKeyValue OperationData \Registry\machine\Schema\wcm://Microsoft-Windows-shell32?version=6.0.6002.18287&language=neutral&processorArchitecture=x86&publicKeyToken=31bf3856ad364e35&versionScope=nonSxS&scope=allUsers\metadata\elements\HKEY_CLASSES_ROOT_lnkfile_shellex_DropHandler_defaultValue, @default, , ewAwADAAMAAyADEANAAwADEALQAwADAAMAAwAC0AMAAwADAAMAAtAEMAMAAwADAALQAwADAAMAAwADAAMAAwADAAMAAwADQANgB9AAAA" Has anyone any idea how to fix this once and for all - reinstalling laptop after laptop from scratch is mildly annoying at work where Office and Firefox are the only extras, but even more annoying at home - I don't fancy going through the palaver of reinstalling everything yet again.

• Can Vista Windows Explorer be repaired/fixed?

  - by gurun8

  I'm running Windows Vista Home Premium on a Sony Vaio laptop. I think somehow my Windows Explorer has become corrupted. I don't recall any certain inciting incident like installing an unreputable 3rd party app or hardware failure but just recently my system won't wake after it's been left idle longer that 20 minutes and goes to sleep. I've also had problems launch certain apps, like Adobe InDesign CS3, that just basically freeze the system but leave mouse movements functioning for a short time before freezing the entire system which requires a hard reboot to resolve the freeze. The system seems to run normally when used but I fear there's a looming possibility that this is a house of cards and will all come crashing down soon. My question is this, can Windows Explorer be repaired/fixed? Before reformatting the system and starting over, which is most likely what I'm going to be forced to do, I'd like explore (no pun intended) my options in fixing the problem with a patch or reinstall or something of that nature. Reformatting my system will eat up a day or two of my time and I just don't have the time to spare right now.

• How can I set the CD audio volume in Linux?

  - by user1296362

  In Windows 7 Control Panel - Sound - Sound Properties window there's an slider for setting CD Audio volume: And it's pretty strange that I can't find corresponding one in generic Linux mixers: alsamixer or amixer. I connected a CD drive to try to set CD audio volume with cdcd (CD Player): $ cdcd setvol 0 Invalid volume It isn't actually an invalid volume, it is because ioctl() call fails. I found that out after searching and changing a bit the source code of this utility (in the libcdaudio): --- cdaudio.c.orig 2004-09-09 06:26:20.000000000 +0600 +++ cdaudio.c 2012-05-30 21:34:34.167915521 +0600 @@ -578,8 +578,10 @@ cdvol_data.CDVOLCTRL_BACK_RIGHT_SELECT = CDAUDIO_MAX_VOLUME; #endif - if(ioctl(cd_desc, CDAUDIO_SET_VOLUME, &cdvol) < 0) - return -1; + if(ioctl(cd_desc, CDAUDIO_SET_VOLUME, &cdvol) < 0) { + printf("*** cd_set_volume: ioctl() returned error\n"); + return -1; + } return 0; } By the way cdcd's get volume command yields rather weird output: Left Right Front 1281734864 32767 Back 0 0 Also I tried aumix: $ aumix -c 0 But all with no success. I read from this manual — http://tldp.org/HOWTO/Alsa-sound-6.html (section 6.2 The mixer) that CD channel can present in amixer output. Maybe some drivers for sound card are missing in my Ubuntu 12.04 LTS installation. Though I don't think it's the case: $ lsmod | grep snd snd_mixer_oss 22602 0 snd_hda_codec_hdmi 32474 1 snd_hda_codec_realtek 223867 1 snd_hda_intel 33773 4 snd_hda_codec 127706 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel snd_hwdep 13668 1 snd_hda_codec snd_pcm 97188 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_seq_midi 13324 0 snd_rawmidi 30748 1 snd_seq_midi snd_seq_midi_event 14899 1 snd_seq_midi snd_seq 61896 2 snd_seq_midi,snd_seq_midi_event snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq snd 78855 19 snd_mixer_oss,snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep ,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 15091 1 snd snd_page_alloc 18529 2 snd_hda_intel,snd_pcm All I need is just mute or set to 0 volume level of CD Audio channel, like I did in Windows 7, to get rid of sibilant noise in the speakers.

• how to prevent other computers from seeing our network computers through vpn

  - by Disco

  We have a local office domain consisting of Windows 7 and XP machines that is running on Windows Server 2008 R2. We also have users that connect via VPN into our network. My concern is that when a remote user opens up a folder, the Network section on the left side of the folder shows the remote user all the computer names in our local network. I would like to go about renaming our computers in the local network with more descriptive computer names, but I do not want the users off-site to be able to see these computer names by simply opening up a folder. (Granted, they can already do this, but our current naming scheme does not link computer names to users.) I would like to change our computer names so we can determine which computer belongs to which user more easily IF it can be done securely. How can I ensure that our local computer names are not showing up in the Network folder for remote, VPN-connected users? My online searches have turned up results where people are advised to turn off Network Sharing and Discovery, but that seems to only ensure that the local machine doesn't see other computer names. I want to prevent OUR computer names from showing up on OTHER computers, and I can't go into the VPN-connected computers and turn off THEIR Network Discovery settings. I would think there is a group policy that would control this but I have not found one yet and I don't know how I would apply it to VPN-connected computers. Thanks! EDIT: That's true, a Group Policy wouldn't run on users only connecting via VPN, good point. What about a VPN/router policy, then?

• Estimating compressed file size using a list parameter

  - by Sai

  I am currently compressing a list of files from a directory in the following format: tar -cvjf test_1.tar.gz -T test_1.lst --no-recursion The above command will compress only those files mentioned in the list. I am doing this because this list is generated such that it fits a DVD. However, during compression the compression rate decreases the estimated file size and there is abundant space left in the DVD. This is something like a Knapsack algorithm. I would like to estimate the compressed file size and add some more files to the list. I found that it is possible to estimate file size using the following command: tar -cjf - Folder/ | wc -c This command does not take a list parameter. Is there a way to estimate compressed file size? I am also looking into options like perl scripts etc. Edit: I think I should provide more information since I have been doing a lot of web search. I came across a perl script(Link)that sort of emulates the Knapsack algorithm. The current problem with the above mentioned script is that it splits the files in their original state. When I compress the files after splitting them, there are opportunities for adding more files which I consider to be inefficient. There are 2 ways I could resolve the inefficiency: a) Compress individual files and save them in a directory using a script. The compressed file could provide a best estimate. I could generate a script using a folder of compressed files and use them on the uncompressed ones. b) Check whether the compressed file's size is less than the required size. If so, I should keep adding files until I meet the requirement. However, the addition of new files to the compressed file is an optimization problem by itself.

• Office 2010 Trusted Locations not working after restart

  - by Josh King

  In Excel 2010, on Windows XP, I am unable to open files - through the open dialog box - from a network drive. The sever has already been added to the Trusted Locations and now most security settings turned down or off. Excel will show "Downloading ..." on that status bar and a progress bar which doesn't progress. We have left Excel sitting in this state for 30+ minutes and no change. A similar problem occurs when saving files to network shares. If we use explorer to navigate to the files and double click them they open flawlessly. No add-ins are active. We also have this problem in Word 2010, but the server was not initially in the Trusted Locations. I added it and it worked until the PC was reset, it now exhibits the same issues as Excel where the server is in the Trusted locations but will not open files. I have tried removing the server from the Trusted Location in both applications, restarting the PC and re-adding them (testing before, after and in-between) and had no luck.

  Hello, first time posting here so I'll try to be very clear. I have a Lenovo S10 Ideapad netbook which fails to boot to an OS. It shows the Lenovo splash screen and can get to the BIOS but it doesn't get to GRUB (was dual booting Ubuntu 9.10 and Win 7, was working fine for months, ie this isn't a new dual boot gone bad). After the splash screen it displays a flashing cursor in the upper left corner. Power cycled to no avail. Here is what I have done trying to narrow the problem down: The machine will boot to Ubuntu using an install/live USB drive, but only if ANOTHER hard drive is installed or NO hard drive is installed. The boot order always lists USB first. Also, there is a 2 gb RAM upgrade but I think that's fine; the Ubuntu USB drive boots fine with it, and "free" sees the whole 2gb of memory. So it seems like the hard drive is bad. I was able to put the bad drive in a different laptop and mount it to recover files. I'm ready to replace the bad hard drive, but I would like to know if this situation makes any sense. If the hard drive is bad, shouldn't I still be able to boot with the Ubuntu USB drive while the bad drive is installed? I would have expected the machine to boot into Ubuntu anyway even if with a bad drive, since the boot order lists USB first. But it seems that when the bad drive is installed, the machine ignores the USB drive and hangs with the flashing cursor. Thanks for any ideas! Sorry for the long post, I just want to put all the info I have up front! Basically I'm going to buy a new drive, but I am mostly curious if this is a typical or at least not unusual situation.

• Visual Studio 2010 Beta 2, built-in font smoothing

  - by L. Shaydariv

  I've just installed Visual Studio 2010 Beta 2 onto my Windows XP to evaluate it and check whether it meets my preferences the way it did before. Okay, I've temporary defeated an urgent bug with a strange workaround (I could not open any file from the Solution Explorer), and it left bad memories to me. But however, it's okay. The first thing I've seen just opening the code editor was ClearType font rendering. Wow, so unexpectedly. I must note that I do not use standard Windows rendering techniques, but I still prefer GDI++, a font renderer developed by Japanese developers. (GDI++ allows to render the fonts in Mac/Win-Safari style over entire Windows.) Personally for me, GDI++ reaches the great font-rendering results allowing me to use the Dejavu Sans Mono font with really nice smoothing in Visual Studio 2008 (VS 2005 too, though VS 2005 crashes in this case). But GDI++ cannot affect Visual Studio 2010 Beta 2 text editor - it uses ClearType (right?), and it does not care about the system font smoothing settings. It could be an editor based on WPF, right? So as far as I can see, I can't use GDI++ anymore because it uses Windows GDI(+) but no WPF? So I've got several questions: Is it possible to disable VS 2010 b2 built-in ClearType or override it with another font smoother? Is it possible to install a Safari-like font renderer for Visual Studio 2010 [betas]? Thanks a lot.

• Vlans and subinterfaces

  - by Adeodatus

  I've inherited a moderate size network that I'm trying to bring some sanity to. Basically, its 8 public class Cs and a slew of private ranges all on one vlan (vlan1, of course). Most of the network is located throughout dark sites. I need to start separating some of the network. I've changed the ports from the main cisco switch (3560) to the cisco router (3825) and the other remote switches to trunking with dot1q encapsulation. I'd like to start moving a few select subnets to different vlans. To get some of the different services provided on our address space (and to separate customers) on to different vlans, do I need to create a subinterface on the router for each vlan and, if so, how do I get the switch port to work on a specific vlan? Keep in mind, these are dark sites and geting console access is difficult if not impossible at the moment. I was planning on creating a subinterface on the router for each vlan then setting the ports with services I want to move to a different vlan to allow only that vlan. Example of vlan3: 3825: interface GigabitEthernet0/1.3 description Vlan-3 encapsulation dot1Q 3 ip address 192.168.0.81 255.255.255.240 the connection between the switch and router: interface GigabitEthernet0/48 description Core-router switchport trunk encapsulation dot1q switchport mode trunk show interfaces gi0/48 switchport Name: Gi0/48 Switchport: Enabled Administrative Mode: trunk Operational Mode: trunk Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: dot1q Negotiation of Trunking: On Access Mode VLAN: 1 (default) Trunking Native Mode VLAN: 1 (default) Administrative Native VLAN tagging: enabled Voice VLAN: none Administrative private-vlan host-association: none Administrative private-vlan mapping: none Administrative private-vlan trunk native VLAN: none Administrative private-vlan trunk Native VLAN tagging: enabled Administrative private-vlan trunk encapsulation: dot1q Administrative private-vlan trunk normal VLANs: none Administrative private-vlan trunk private VLANs: none Operational private-vlan: none Trunking VLANs Enabled: ALL Pruning VLANs Enabled: 2-1001 Capture Mode Disabled Capture VLANs Allowed: ALL Protected: false Unknown unicast blocked: disabled Unknown multicast blocked: disabled Appliance trust: none So, if the boxen hanging off of gi0/18 on the 3560 are on an unmanaged layer2 switch and all within the 192.168.0.82-95 range and are using 192.168.0.81 as their gateway, what is left to do, especially to gi0/18, to get this working on vlan3? Are there any recommendations for a better setup without taking everything offline?

• How do I create an MBR on a USB stick using DD command line tool

  - by Lana Miller

  Okay I'm trying to create a BOOTABLE Windows7 image on a USB key from a Mac running Lion. My image is .iso format. I tried: sudo dd if=/Users/myusername/Win7.iso of=/dev/disk1 bs=1m And this succeeded in writing the files, except in DISK UTILITY on the mac, it shows the partition type as GUID Partition Table and not 'Master Boor Record'. Booting the key on my Vista computer yields the error "No boot sector on USB Device' From what I can tell, bs=1m in the DD command should have left 1 Megabyte for the boot sector, but for some reason this area of the USB Key is not set up correctly so that it will boot How can I fix this, or correctly use dd to write a bootable cd image such that it is now a bootable usb drive? Note: in the instructions I read about, they recommended renaming my Win7.iso to Win7.dmg before using DD, which made absolutely no sense to me, so I didn't do it. I could try with that step now, but it takes 1.99 hours to write the image to the USB drive so there is a huge penalty to trial and error here. Thank you.

• IIS 7 doesn't do a 301 redirect

  - by rohde

  Hi there! I have just migrated some sites to IIS7 from IIS6, and am experiencing problems with one of the sites. When a request comes in for the site (www.ourdomain.com/site1/) with a trailing slash everything is fine. But if the trailing slash is left out (www.ourdomain.com/site1), then the request fails. Apparently it doesn't do a 301 redirect on the slashl-less URL, resulting in ASP.NET throwing an exception. This is not happening with the other sites at the same domain. What can be the cause of this? EDIT: The exception I get is this: System.Web.HttpException: Failed to Execute URL. at System.Web.Hosting. ISAPIWorkerRequestInProcForIIS6.BeginExecuteUrl(String url, String method, String childHeaders, Boolean sendHeaders, Boolean addUserIndo, IntPtr token, String name, String authType, Byte[] entity, AsyncCallback cb, Object state) at System.Web.HttpResponse.BeginExecuteUrlForEntireResponse(String pathOverride, NameValueCollection requestHeaders, AsyncCallback cb, Object state) at System.Web.DefaultHttpHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

• Microsoft Application Request Routing with Windows Authentication

  - by theplatz

  I'm running into a problem trying to get Windows Authentication working in an environment that uses Microsoft Application Request Routing and was hoping someone might be able to help. The problem I'm running into is that only some requests are authenticated, while others fail with 401 errors. I have followed the Special Case of Running IIS 7.0 in a Web Farm instructions found at http://blogs.msdn.com/b/webtopics/archive/2009/01/19/service-principal-name-spn-checklist-for-kerberos-authentication-with-iis-7-0.aspx to no avail. My current server setup looks like the following: ARR Two servers set up with IIS shared configuration using IIS 7.5 on Windows 2008 R2 Anonymous authentication turned on for the Default Web Site Web Farm Two servers running IIS 7.5 on Windows 2008 R2 Three web sites set up using port binding to differentiate between virtual hosts. Ports being used are 8000, 8001, and 8002 Application pools for Windows Authentication all use a common domain account SPN added to domain account for http/<virthalhost-name>:<port-number> and http/<virtualhost-name>.<fully-qualified-domain>:<port-number> The IIS logs show the following when authentication is working/failing. If I understand correctly, all requests should show DOMAIN\User_Name: 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/stylesheets/techweb.landing.css - 8002 DOMAIN\User_Name ARR-HOST-1-IP-ADDRESS 200 0 0 62 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-background-right.gif - 8002 - ARR-HOST-1-IP-ADDRESS 401 2 5 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-background-left.gif - 8002 DOMAIN\User_Name ARR-HOST-IP-ADDRESS 200 0 0 31 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-icon.png - 8002 - ARR-HOST-1-IP-ADDRESS 401 2 5 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-icon.png - 8002 - ARR-HOST-1-IP-ADDRESS 401 1 2148074248 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/application-icon.png - 8002 - ARR-HOST-1-IP-ADDRESS 401 1 2148074248 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-background-right.gif - 8002 - ARR-HOST-1-IP-ADDRESS 401 1 3221225581 15 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/building.gif - 8002 DOMAIN\User_Name ARR-HOST-2-IP-ADDRESS 200 0 0 218 Does anyone know what might cause this problem and how I can resolve it?

• How do I Install Intermediate Certificates (in AWS)?

  - by getmizanur

  I have installed private key (pem encoded) and public key certificate (pem encoded) on Amazon Load Balancer. However, when I check the SSL with site test tool, I get the following error: Error while checking the SSL Certificate!! Unable to get the local issuer of the certificate. The issuer of a locally looked up certificate could not be found. Normally this indicates that not all intermediate certificates are installed on the server. I converted crt file to pem using these commands from this tutorial: openssl x509 -in input.crt -out input.der -outform DER openssl x509 -in input.der -inform DER -out output.pem -outform PEM During setup of Amazon Load Balancer, the only option I left out was certificate chain. (pem encoded) However, this was optional. Could this be cause of my issue? And if so; How do I create certificate chain? UPDATE If you make request to VeriSign they will give you a certificate chain. This chain includes public crt, intermediate crt and root crt. Make sure to remove the public crt from your certificate chain (which is the top most certificate) before adding it to your certification chain box of your Amazon Load Balancer. If you are making HTTPS requests from an Android app, then above instruction may not work for older Android OS such as 2.1 and 2.2. To make it work on older Android OS: go here click on "retail ssl" tab and then click on "secure site" "CA Bundle for Apache Server" copy and past these intermediate certs into certificate chain box. just incase if you have not found it here is the direct link. If you are using geo trust certificates then the solution is much the same for Android devices, however, you need to copy and paste their intermediate certs for Android.

• How can I make Internet Explorer 6 render Web pages like Internet Explorer 11?

  - by gparyani

  Now, I know that this may seem like a bad question in that I can just upgrade to Internet Explorer 8, but I am sticking with IE6 in that IE8 removes valuable features, like the ability to save favorites offline and the fact that a file path turns into a Windows Explorer window and typing a Web address into Windows Explorer changes it into an IE window. I know that Internet Explorer 6 does a really bad job at rendering some pages. I know of the Google Chrome Frame extension that brings Chrome-style rendering into IE, but that will soon be discontinued. So, I tried another thing: I know that C:\Windows\System32\mshtml.dll contains the Trident rendering engine that is used by IE, so I tried something: I first backed up the original file by renaming it on Windows XP to mshtml-old.dll, then I tried to copy in the DLL from a computer running Windows 7 with Internet Explorer 10. I noticed that, after copying, the system had replaced the new DLL with the old one, but left the one I backed up intact. Is there any way I can get the system to not replace the DLL like that so that I can transfer in IE11's mshtml.dll into Windows XP and make IE6 render like IE11? I'm looking for an answer that describes how to tweak my system to make IE6 render like IE11 (or IE10), not one that tells me to upgrade IE or install another browser. I don't care how tedious the method is, just as long as it works.
