  • Software RAID underneath ESXi datastore

    - by carlpett
    I'm building an virtual environment for a small business. It is based around a single ESXi 5.1 host, which will host half a dozen or so VMs. I'm having some doubts regarding how to implement the storage though. I naturally want the datastore to be fault tolerant, but I can't get the funds for a separate storage machine, nor expensive hardware RAID solutions, so I would like to use some software RAID (lvm/mdadm, most likely). How can this be implemented? My only idea so far would be to create a VM which has the storage adapter as passthrough, puts some software RAID on top of the disks and then presents the resulting volumes "back" to the ESXi host which then creates a datastore from which other VMs get their storage presented. This does seem kind of round-about, do I have any better options? From my research, passthrough seems to come with quite a few drawbacks, such as no suspend/resume etc.

  • Book Recommendations for Technical/Solutions Architecture [closed]

    - by giant_squid
    I wish to learn more about Technical and Solutions Architecture. Specifically, I'm concerned with designing HA, Fault-Tolerant Scalable web-based solutions (enough buzzwords ;-). Its a topic I'm familiar with on a technical level having worked as a sysadmin, but I don't know all the buzzwords Architects use and have to brush up on my UML and diagram techniques. I would like a book that describes what architecture is as a discipline and explores standard design patterns, and some do's and don'ts. Do you have any recommendations? I apologise if this sounds vague, its because I am still learning what Architecture is as a discipline having come from a sysadmin background. To be 100% clear I'm looking for books or websites that give broad overviews of what System Design patterns exist and how the discipline works. Thanks Instead of closing the question maybe you could comment on what exactly about it you don't like.

  • Cannot open mailbox

    - by AdamL
    Ive got a server running Windows Server 2012 and Exchange 2013 on my local domain. Ive got the mailboxes setup and can send/receive emails fine when using OWA. If i try to open the mailbox using Outlook 2010, I get the below error If i try to expand the folder, i get the same message but am still able to use OWA. When I try to run a send/receive, I get the below error: After a bit of researching on the web, people suggest that the profile is corrupt. I have recreated the profile and tried again but still same error. Another post has suggested that the issue is DNS and client PCs should be able to resolve autodiscover.domain.local and server.domain.local to the IP of the server. This is fine on my network. Every user has got the same issue and I am struggling to identify what is causing the fault. Advise appreciated.

  • Apache timeouts and error log

    - by BlackFire27
    I have an error whenever I run my code for a certain time. I use a lot of loops and sql connections. I basically, put and take out links from my database. The problem is that there is some error thrown that I cant see, whenever I execute a long sql operation .. Note that the fault isnt the code. The code runs well, whenever there are a few links involved. But when there are over 200 links.. an error is thrown that I cants see. I tried to trace the error in a few places: C:\Program Files\Zend\ZendServer\logs\php_error.log C:\Program Files\Zend\phpMyAdmin\config.inc.php Edit Viewer in win xp I am running XP: Windows xp php version: 5.3.9-ZS5.6.0. Apache/2.2.21 Apacher version: (Win32) mod_ssl/2.2.21 OpenSSL/0.9.8o I cant trace the error at all, and why it happens. All I can suspect of, is that there is a server timeout..

  • Upgrade PHP 5.1.6 to 5.2.x on Fedora 6 - Solutions?

    - by nicorellius
    I have a CRM on an old Fedora server, running Apache 2.2.6, MySQL 5.0.27, and PHP 5.1.6. I see a couple of options to fix my problem, but I thought I would consult the pros on this one here at Server Fault to see if I'm missing anything. This is after spending a good while searching the net for solutions. Option 1 Upgrade Fedora, step-wise, to Fedora 7 and then to 8, and then the PHP packages I need would be available. I know this is hazardous, because of repository location, dependencies, etc. Option 2 Upgrade using this method. This may or may not work, and so would be considered a crap shoot. I consulted some IT people and they say the best best is to back up data and build a new server with updated hard and software. I happen to agree, but wanted to exhaust all my resources first.

  • Why can I browse to localhost, not to my computer name? (IIS7) [closed]

    - by Lost Hobbit
    I'm not very clued up on IIS, but I'm trying to do something that I thought would be quite simple. In IE, if I browse to http://localhost:80, I am greeted with a pretty picture with a bunch of welcome messages and a big "IIS7", thanks to the graphic designers at Microsoft. In IE, if I browse to http://mycomputername:80, I'm greeted with 404. It may be my fault... perhaps I've done something weird. Chrome replies 404 to either of those. Should this work, and if so, what am I doing wrong, or what can I do to get it to work? What might cause this to happen and how can I fix it? EDIT To add a bit more information. I did find after posting this question that http://localhost:80 was the only URL I could access on my local PC. I could not access any of the virtual sub-directories on localhost via my browser.

  • Recent Innovations to ILOM

    - by B.Koch
    by Josh Rosen If you are wondering how Oracle can make some of the most advanced, reliable, and fault tolerant servers on the market, look no further than Oracle Integrated Lights Out Manager or ILOM.  We build ILOM into every server we create, from Oracle x86 Systems such as X3-2 to the SPARC T-Series family. Oracle ILOM is an embedded service processor, but it's really more than that.  It's a computer within a computer.  It's smart, it's tightly integrated into all aspects of the server's operation, and it's a big reason why Oracle servers are used for some of the most mission-critical workloads out there. To understand the value of ILOM, there is no better place to start than its fault management capability.  We have taken the sophisticated fault management architecture from Solaris, developed and refined over a decade, and built it into each and every ILOM. ILOM detects a potential issue at its earliest stage, watching low-level sensors.   If the root cause of a problem is not clear from a single error reading, ILOM will look for other clues and combine multiple pieces of information to correctly identify a failing component. ILOM provides peace of mind. We tailor our fault management for each new server platform that we produce.  You can rest assured that it's always actively keeping the server healthy.  And if there is a problem, you can be confident it will let you know by sending you a notification by e-mail or trap. We also heard IT managers tell us they needed a Ph.D. in computer engineering to manage today's servers. It doesn't have to be that way.  Thanks to the latest innovations to Oracle ILOM, we present hardware inventory and status in way that makes sense – to anyone.  Green means everything is healthy and red means something is wrong.  When a component needs to be replaced a clear message indicates where the problem is and points you at a knowledge article about that problem.  It's that simple. Simpler management and simple interfaces mean reduced complexity and lower costs to manage.  And we know that's really important. ILOM does all this while also providing advanced service processor features you depend on for managing enterprise class systems.  You can remotely control the server power, interact with a virtual video console for the server, and mount media on the server remotely.  There is no need to spend money on a KVM switch to get this functionality. And when people hear how advanced ILOM is, they can't believe ILOM is free.  All features are enabled and included with each Oracle server that you buy.  There are no advanced licenses you need to purchase or features to unlock. Configuring ILOM has also never been easier.  It is now possible to configure almost all aspects of the server directly from ILOM.  This includes changing BIOS settings, persistently modifying boot order, and optimizing power settings -- all directly from ILOM. But Oracle's innovation does not stop with ILOM.  Oracle has engineered Oracle Enterprise Manager Ops Center to integrate directly with ILOM, providing centralized management across all of our servers. Ops Center will discover each of your Oracle servers over the network by searching for ILOMs.  When it finds one, it knows how to communicate with ILOM to monitoring and configure that server from application to disk. Since every server that Oracle produces, from x86 Systems to SPARC T-Series up and down the line, comes with Oracle ILOM, you can manage all Oracle servers in the same way.  And while all of our servers may have different components on the inside, each with their specialized functions, the way you integrate them and the way you monitor and manage them is exactly the same. Oracle ILOM is state-of-art.  If you are looking for a server that make systems management simple and is easy to integrate and maintain, check out the latest advances to Oracle ILOM. Josh Rosen is a Principal Product Manager at Oracle and previously spent more than a decade as a developer and architect of system management software. Josh has worked on system management for many of Oracle's hardware products ranging from the earliest blade systems to the latest Oracle x86 servers.

  • What are the files pushed to MDS?

    - by harsh.singla
    All files which are under AIAComponents will move to MDS. This contains EnterpriseObjectLibrary, EnterpriseBusinessServiceLibrary, ApplicationObjectLibrary, ApplicationBusinessServiceLibrary, B2BObjectLibrary, ExtensionServiceLibrary, and UtilityArtifacts. Also there are some common transformation (.xsl) files, which are kept under Transformations folder, moved to MDS. AIAConfigurationProperties.xml file will be there in MDS. Every cross reference (.xref) object will also be there. Every Domain value Map (.dvm) will also be there. Common fault policy, which by default included in composite during composite generation, if a user does not choose to customize fault policy. All these files are location under AIAMetaData directory and then placed in their respective folders. We are planning to put Error handling and BSR systems related data also to MDS.

  • Writing custom Message Formatter for SOAP basicHttpBinding

    - by Lijo
    I have a WSDL published by our service development team. It is using SOAP and basicHttpBinding. I can add the service reference to the project using Add Service Reference option in Visual Studio. I need to develop the WCF client. I need to use custom Message Formatter (for mapping between Messages and CLR types). Can you please show how to write the custom Message Formatter (in C# )for the following wsdl?

  • How do I recover from upgrading while using bad version of gcc/binutils?

    - by Shawn J. Goff
    I upgraded from 9.04 to 10.10 a couple of days ago, and things are really messed up - X is crashing constantly. Since then, I had an application segfault for no reason, when I was debugging, I found that it was strlen() that was causing the segfault (pointing to libc being the problem)! Upon investigation, I found that it was because I had a bad version of gcc and binutils installed in /usr/bin/local; I removed it, recompiled the application, and it no longer crashes. Now, looking at my logs, I see that X is also crashing due to libc. Backtrace: 0: /usr/bin/X11/X (xorg_backtrace+0x3b) [0x80ef31b] 1: /usr/bin/X11/X (0x8048000+0x5d00d) [0x80a500d] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0xb77e240c] 3: /usr/bin/X11/X (0x8048000+0xbb0b6) [0x81030b6] 4: /usr/bin/X11/X (0x8048000+0xbc3ef) [0x81043ef] 5: /usr/bin/X11/X (0x8048000+0x26ee7) [0x806eee7] 6: /usr/bin/X11/X (0x8048000+0x1a5da) [0x80625da] 7: /lib/libc.so.6 (__libc_start_main+0xe7) [0xb750ace7] 8: /usr/bin/X11/X (0x8048000+0x1a1b1) [0x80621b1] Segmentation fault at address 0x32156654 Caught signal 11 (Segmentation fault).

  • Subterranean IL: Exception handling 1

    - by Simon Cooper
    Today, I'll be starting a look at the Structured Exception Handling mechanism within the CLR. Exception handling is quite a complicated business, and, as a result, the rules governing exception handling clauses in IL are quite strict; you need to be careful when writing exception clauses in IL. Exception handlers Exception handlers are specified using a .try clause within a method definition. .try <TryStartLabel> to <TryEndLabel> <HandlerType> handler <HandlerStartLabel> to <HandlerEndLabel> As an example, a basic try/catch block would be specified like so: TryBlockStart: // ... leave.s CatchBlockEndTryBlockEnd:CatchBlockStart: // at the start of a catch block, the exception thrown is on the stack callvirt instance string [mscorlib]System.Object::ToString() call void [mscorlib]System.Console::WriteLine(string) leave.s CatchBlockEnd CatchBlockEnd: // method code continues... .try TryBlockStart to TryBlockEnd catch [mscorlib]System.Exception handler CatchBlockStart to CatchBlockEnd There are four different types of handler that can be specified: catch <TypeToken> This is the standard exception catch clause; you specify the object type that you want to catch (for example, [mscorlib]System.ArgumentException). Any object can be thrown as an exception, although Microsoft recommend that only classes derived from System.Exception are thrown as exceptions. filter <FilterLabel> A filter block allows you to provide custom logic to determine if a handler block should be run. This functionality is exposed in VB, but not in C#. finally A finally block executes when the try block exits, regardless of whether an exception was thrown or not. fault This is similar to a finally block, but a fault block executes only if an exception was thrown. This is not exposed in VB or C#. You can specify multiple catch or filter handling blocks in each .try, but fault and finally handlers must have their own .try clause. We'll look into why this is in later posts. Scoped exception handlers The .try syntax is quite tricky to use; it requires multiple labels, and you've got to be careful to keep separate the different exception handling sections. However, starting from .NET 2, IL allows you to use scope blocks to specify exception handlers instead. Using this syntax, the example above can be written like so: .try { // ... leave.s EndSEH}catch [mscorlib]System.Exception { callvirt instance string [mscorlib]System.Object::ToString() call void [mscorlib]System.Console::WriteLine(string) leave.s EndSEH}EndSEH:// method code continues... As you can see, this is much easier to write (and read!) than a stand-alone .try clause. Next time, I'll be looking at some of the restrictions imposed by SEH on control flow, and how the C# compiler generated exception handling clauses.

  • Do PHP-FPM (and other PHP handlers) need execute permissions on the PHP files they're serving?

    - by Andrew Cheong
    I read in a post at Server Fault that PHP-FPM needs execute permissions. However, the answer in When creating a website, what permissions and directory structure? only grants read and write permissions to PHP-FPM. Maybe I don't quite understand how PHP handlers (or CGI in general) work, but the two claims seem contradictory to me. As I understand, when Apache / Nginx gets a request for foobar.php, it "passes" the file to an appropriate handler. That is, I imagine it's as if www-root (or apache or whomever the webserver's running as) were to run some command, /usr/sbin/php-fpm foobar.php Actually, no, that's naive, I just realized. PHP-FPM must be a running instance (if it's to be performant, and cache, etc.), so probably PHP-FPM is just being told, "Hey, quick, process this file for me!" In either case, I don't see why execute permissions are necessary. It's not like the webserver needs to literally execute the file, i.e. ./foobar.php Is the Server Fault answer simply mistaken?

  • Should you salary reflect how much work there is for you or does that not matter? [closed]

    - by Kevin Simper
    I am working in a consulting company, where the company mostly do IT support. The website is also only focused on IT support, and we do not therefore capture leads for the Web Department. We aim for Small busniess, which needs new computers and firewalls. We were having a performance conversation and talked about salary and my employer told that he was not impressed by the revenue I was generating. I told that I did not have enough work and I would like to get more tasks and project so that i could reach the goal, but that i did not think it was my fault that there was not enough work. He said that it was not his fault either, but he could not pay me more. Is he right that I should not get paid more just because my employee can not get enough Web projects, or should i be paid what i am worth not based on the work amount the sales generate?

  • Wine throwing errors since going to 13.10

    - by serilain
    After upgrading to Ubuntu 13.10, running any program in Wine produces the following errors (via CLI): wine: Unhandled page fault on read access to 0x00000000 at address (nil) (thread 000f), starting debugger... wine: Unhandled page fault on read access to 0x00000000 at address (nil) (thread 0014), starting debugger... wine client error:14: write: Bad file descriptor err:wineboot:start_services_process Unexpected termination of services.exe - exit code -1073741819 (These also generate two popup windows saying that an undefined application has crashed). After this, the program I was trying to run in the first place executes as normal. Any idea how to fix this?

  • Weird sound problems after upgrading to 13.10 (macbook)

    - by Atsch
    I have been having a very weird problem with my sound lately: 1)My right channel is extremely disorted with relativly loud noises, tested with several headphones. 2) After a while, wiered noises start coming from my speakers 3) playing lots of sounds at once causes the the output to become really mushed, e.g. in lmms or games. all points to a: a fault in my sound card, or b: a fault in alsa or pulseaudio, but I don't know how to find out. I will now try using the alsa-daily, and edit this away depending on my results after a restart

  • Did I find a bug in PHP's `crypt()`?

    - by Nathan Long
    I think I may have found a bug in PHP's crypt() function under Windows. However: I recognize that it's probably my fault. PHP is used by millions and worked on by thousands; my code is used by tens and worked on by me. (This argument is best explained on Coding Horror.) So I'm asking for help: show me my fault. I've been trying to find it for a few days now, with no luck. The setup I'm using a Windows server installation with Apache 2.2.14 (Win32) and PHP 5.3.2. My development box runs Windows XP Professional; the 'production' server (this is an intranet setup) runs Windows Storage Server 2003. The problem happens on both. I don't see anything in php.ini related to crypt(), but will happily answer questions about my config. The problem Several scripts in my PHP app occasionally hang: the page sits there on 'waiting for localhost' and never finishes. Each of these scripts uses crypt to hash a user's password before storing it in the database, or, in the case of the login page, to hash the entered password before comparing it to the version stored in the database. Since the login page is the simplest, I focused on it for testing. I repeatedly logged in, and found that it would hang maybe 4 out of 10 times. As an experiment, I changed the login page to use the plain text password and changed my password in the database to its plain text version. The page stopped hanging. I saw that PHP's latest version lists this bugfix: Fixed bug #51059 (crypt crashes when invalid salt are [sic] given). So I created a very simple test script, as follows, using the same salt given in an official example: $foo = crypt('rasmuslerdorf','r1'); echo $foo; This page, too, will hang, if I reload it like crazy. I only see it hanging in Chrome, but regardless of browser, the effect on Apache is the same. Effect on Apache When these pages hang, Apache's server-status page (which I explained here, regarding a different problem) increments the number of requests being processed and decrements the number of idle workers. The requests being processed almost all have a status of 'Sending Reply,' though sometimes for a moment they will show either 'Reading request' or 'keepalive (read).' Eventually, Apache may crash. When it does, the Windows crash report looks like this: szAppName: httpd.exe szAppVer: 2.2.14.0 szModName: php5ts.dll szModVer: 5.3.1.0 // OK, this report was before I upgraded to PHP 5.3.2, // but that didn't fix it offset: 00a2615 Is it my fault? I'm tempted to file a bug report to PHP on this. The argument against it is, as stated above, that bugs are nearly always my fault. However, my argument in favor of 'it's PHP's fault' is: I'm using Windows, whereas most servers use Linux (I don't get to choose this), so the chances are greater that I've found an edge case There was recently a bug with crypt(), so maybe it still has issues I have made the simplest test case I can, and I still have the problem Can anyone duplicate this? Can you suggest where I've gone wrong? Should I file the bug after all? Thanks in advance for any help you may give.

  • Wacom consumer tablet driver service may crash while opening Bamboo Preferences, often after resuming computer from sleep

    - by DragonLord
    One of the ExpressKeys on my Wacom Bamboo Capture graphics tablet is mapped to Bamboo Preferences, so that I can quickly access the tablet settings and view the battery level (I have the Wireless Accessory Kit installed). However, when I connect the tablet to the computer, in wired or wireless mode, and attempt to open Bamboo Preferences, the Wacom consumer tablet driver service may crash, most often when I try to do so after resuming the computer from sleep. There is usually no direct indication of the crash (although I once did get Tablet Service for consumer driver stopped working and was closed), only that the cursor shows that the system is busy for a split second. When this happens, the pen no longer tracks on the screen when in proximity of the tablet (even though it is detected by the tablet itself); however, touch continues to function correctly. To recover from this condition, I need to restart the tablet driver services. I got tired of having to go through Task Manager to restart the service every time this happens, so I ended up writing the following command script, with a shortcut on the desktop for running it with elevated privileges: net stop TabletServicePen net start TabletServicePen net stop TouchServicePen net start TouchServicePen Is there something I can do to prevent these crashes from happening in the first place, or do I have have to deal with this issue until the driver is updated? Windows 7 Home Premium 64-bit. Tablet drivers are up to date. Technical details Action Center gives the following details about the crash in Reliability Monitor: Source Tablet Service for consumer driver Summary Stopped working Date ?10/?15/?2012 2:48 PM Status Report sent Description Faulting Application Path: C:\Program Files\Tablet\Pen\Pen_Tablet.exe Problem signature Problem Event Name: APPCRASH Application Name: Pen_Tablet.exe Application Version: 5.2.5.5 Application Timestamp: 4e694ecd Fault Module Name: Pen_Tablet.exe Fault Module Version: 5.2.5.5 Fault Module Timestamp: 4e694ecd Exception Code: c0000005 Exception Offset: 00000000002f6cde OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1033 Additional Information 1: 9d4f Additional Information 2: 9d4f1c8d2c16a5d47e28521ff719cfba Additional Information 3: 375e Additional Information 4: 375ebb9963823eb7e450696f2abb66cc Extra information about the problem Bucket ID: 45598085 Exception code 0xC0000005 means STATUS_ACCESS_VIOLATION.

  • What does this diagnostic output mean?

    - by ChrisF
    I recently had a fault with my broadband connection. It turned out to be a fault with the ISP's or teleco's equipment. My ISP posted this diagnostic, but while I understand it in general, I'd like to to know more about the details. I'm assuming that ATM means Asynchronous Transfer Mode and PPP means Point to Point Protocol. It was this that my router was indicating as the fault. xDSL Status Test Summary Sync Status: Circuit In Sync General Information NTE Status: NTE Power Status: Unknown Bypass Status: Upstream DSL Link Information Downstream DSL Link Information Loop Loss: 9.0 17.0 SNR Margin: 25 15 Errored Seconds: 0 0 HEC Errors: 0 Cell Count: 0 0 Speed: 448 8128 TAM Status: Successfully executed operation Network Test: Sub-Test Results Layer Name Value Status Modem pass Transmitter Power (Upstream) 12.4 dBm Transmitter Power (Downstream) 8.8 dBm Upstream psd -38 dBm/Hz Downstream psd -51 dBm/Hz DSL pass Equipment Vendor Name TSTC Equipment Vendor Id n/a Equipment Vendor Revision n/a Training Time 8 s Num Syncs 1 Upstream bit rate 448 kbps Downstream bit rate 8128 kbps Upstream maximum bit rate 1108 kbps Downstream maximum bit rate 11744 kbps Upstream Attenuation 3.5 dB Downstream Attenuation 0.0 dB Upstream Noise Margin 20.0 dB Downstream Noise Margin 19.0 dB Local CRC Errors 0 Remote CRC Errors 0 Up Data Path interleaved Down Data Path interleaved Standard Used G_DMT INP INP Upstream Symbols n/a INP Upstream Delay 4 ms INP Upstream Depth 4 INP Downstream Symbols n/a INP Downstream Delay 5 ms INP Downstream Depth 32 ATM Reason: No ATM cells received fail Number of cells transmitted 30 Number of cells received 0 number of Near end HEC errors 0 number of Far end HEC errors n/a PPP Reason: No response from peer fail PAP authentication nottested CHAP authentication nottested (I'm not sure that Super User is the best place to ask this, but two people have suggested I ask it here so here I am).

  • Microsoft Word "Random" Crashes

    - by Bent Rasmussen
    Word seemingly randomly crashes in an application setting where it is first being used to programmatically databind (bookmarks) and then directly afterwards opened on the user machine for further user input. The error message is quite precise but the workaround has eluded me. Word crashes a moment or two after it has been opened on the user machine with the below exception details. Problem signature: Problem Event Name: APPCRASH Application Name: WINWORD.EXE Application Version: 14.0.6129.5000 Application Timestamp: 5082f354 Fault Module Name: wwlib.dll Fault Module Version: 14.0.6129.5000 Fault Module Timestamp: 5082f3dc Exception Code: c0000005 Exception Offset: 000eed32 OS Version: 6.1.7601.2.1.0.16.7 Locale ID: 1030 Additional information about the problem: LCID: 1030 skulcid: 1030 Sometimes one can run the exact same scenario 50 times before experiencing a crash, other times only a few times. We have tried using different versions of the Word format as well as renaming the databound file after saving so that the file being opened on the user machine is different. Principally Word should never crash but perhaps there is some workaround that can make Word not crash. Googling for a solution there appears to be multiple things that can trigger this bug.

  • Utilu IE Collection IE6 crashes under Windows 7

    - by Aron
    I've installed Utilu IE Collection under Windows 7 64-bit, but am unable to successfully run IE6 (specifically, "Internet Explorer 6.0 (6.00.2900.2180)"). I haven't tried other versions of IE from the package, so their behavior is unknown. It starts up fine, but the address bar isn't shown. (Attempted to post image, but I'm a newbie on SU and it wouldn't let me. Can be found here.) View-Toolbars shows 'Address Bar' already selected. If I try to (de-)select Address Bar in that list, it crashes: Problem signature: Problem Event Name: APPCRASH Application Name: iexplore.exe Application Version: 6.0.2900.2180 Application Timestamp: 41107b81 Fault Module Name: StackHash_e162 Fault Module Version: 0.0.0.0 Fault Module Timestamp: 00000000 Exception Code: c0000005 Exception Offset: 00000000 OS Version: 6.1.7600.2.0.0.256.48 Locale ID: 1033 Additional Information 1: e162 Additional Information 2: e1625455580a00d3fda64a8cdf366fbb Additional Information 3: 58c7 Additional Information 4: 58c75753c6745fad91929ab6430a83fa That's not all that's wrong ('Search' pane has no contents as well, probably more), but it's the most glaring problem. I've seen some allusions to a registry change needed to fix this, but haven't been able to find any details. Anybody? I'm running the latest version of the collection, 1.7.0.6.

  • Problems with cross forest authentication in SQL Reporting

    - by chunkyb2002
    We're currently running an SQL 2008 R2 Cluster with Reporting Services running, all for use with System Center Operations Manager 2007 R2 (RU3). Our users are on a different domains to the SCOM and SQL servers (we have two domains as we are in the process of a domain migration) We have no problems at all with users accessing reports via the SCOM Console or the Web interface if they are on the new domain which runs at 2008 R2 functional level. However users on the old domain (which runs at a 2003 functional level) cannot access reports on SCOM or via the web interface (http://sqlserver/reports) The error we get is: An error occurred when invoking the authorization extension. (rsAuthorizationExtensionError) For more information about this error navigate to the report server on the local server machine, or enable remote errors Taking the errors advise we logged on to the SQL server as a user on the old domain (which works fine!) and then try to authenticate with the reporting via the web interface which produces this most useful of errors: An error occurred when invoking the authorization extension. (rsAuthorizationExtensionError) The creator of this fault did not specify a Reason. Things we've tried: Recreating the trust between domains Ensuring the SQL Reporting service account was a member of Windows Authorization Access Group on the 2003 domain Added users on the 2003 domain explicitly to the Reporting Users group on the SQL Server Has anyone come across this issue before perhaps in a different scenario? If so how was it resolved? Thanks in advance for any help.
