• Disaster Recovery Standby Server

  - by user64300

  Hi, I work for a small business with 25 users and 2 servers. 1 server is the DC running Windows Server 2003/Exchange 2003. We want a reliable disaster recovery strategy for this server without having to spend a lot of money. We take regular backups but I have been advised that only an identical server will allow them to be restored easily. I'm trying to come up with a solution that means we don't have to buy two servers at twice the cost everytime we upgrade. I'm toying with the idea of upgrading our DC more frequently (say every 3 years) and then using the old server as the recovery server (temporarily - until we can source a replacement server). However, I won't know whether the backups will restore on the old server until I try it! We're planning to upgrade to Server 2008R2 in the near future so I'm hoping the backup tools will give me some success in restoring to different hardware (or perhaps I can use hyper-v if not). So what I am wondering is whether it is a idea to use old hardware as a disaster recovery strategy (providing we regular test it obviously!).

• NAS for Mac OS X Server

  - by SamAdmin

  I'm using Mac OS X Server and want to allow the users that connect to their network accounts to store their data on a NAS drive. I want the users to connect to the Lion server as this allows for better policies and management for me and for their afp share to be located on a NAS drive. I've looked into home directories and network logins however I don't want the users to connect into a different login environment, just an authentication against their provided account on the Lion server and for their finder to take them to their own storage area - located on the NAS drive. Currently I am using FreeNAS for both authentication and storage however there are getting to be far too many people to manage each afp share and account, plus just using FreeNAS is extremely limiting for expansion and if something goes wrong with 1 entity the entire system goes down. Using the Lion server for user accounts and policies will be much better for this expanding business. I have looked into LDAP, using the Lion server as an LDAP server to authenticate against for FreeNAS however I have had issues with this and thought a different approach could be better from the other side of the situation... Providing the account with somewhere to store data rather than the afp share authenticating against an LDAP server. I am wrong to try it this way? Is it possible to logically add storage to a Mac OS X Server which can be recognised as a local drive, so can be used for network accounts?

• How to track things that SHOULD happen, but might not have

  - by Kamiel Wanrooij

  I am running into a couple of issues with some applications we've deployed and maintain. I have the feeling we have approached this with some anti-patterns up to now, but I would like to see how to make this more flexible and stable. In one situation, we have a server at a client which pushes data to us to parse every night (yes, Windows Task Scheduler). This is highly unstable however, so once every month this doesn't happen because of reasons out of our control. This heavily impacts our business since we run with stale data in that situation. In another scenario we have a lot of background job processes that should be running. We already keep them up using bluepill ( http://www.github.com/arya/bluepill ) but obviously restarts happen, both automatically and manually, and people forget things or systems mess up. What I would like to track is events that should occur or should be available. Like the existence of a process, the execution of a program, or the creation/age of a file, and track it when they don't happen or exist. We develop most things in Ruby on Rails, use NewRelic, Bluepill and Munin, and run on Ubuntu. I've been toying around with counting ps aux | grep processname | wc -l in Munin scripts, or capturing the age of a file and raising alerts over 24-26 hours, stuff like that. Is there better tooling to track things that should happen, and raise alerts if they don't? P.S. I know some things are suboptimal, like manually having to define bluepill for applications and then forgetting to do so. The same goes for the push based approach of the first application, a dedicated daemon that manages that on the client side that we control and can track its connection to us might be a much better solution.

• SBS 2008 Sharepoint Database good Memory Limit.

  - by ldelgado

  I manage a small network running on Small Business Server 2008. Lately, the Sharepoint embedded database is getting out of control with its memory usage. I've got a total of 16 GB of RAM on this server, and the Sharepoint database sometimes uses almost 8 GB of RAM. This never happened before, and it started happening after I installed Backup Exec 2010. It happens after a backup is performed. So I suspect there is a memory leak involved. I am working on that issue, but this question isn't about that. I would like to limit the amount of memory the Embedded database uses. I know how to do it. My question is, what would be the ideal amount of memory that I can allocate to Sharepoint? There are only 4 users on my network. One of the users uses two computers but not at the same time. They use sharepoint for a company calendar, and sometimes they share files that way also. Let me know if you need to know anything else. Thanks,

• Security Token for Mac/Linux/Windows, self-managed, pref. open source?

  - by DevelopersDevelopersDevelopers

  I'm looking to buy an evaluation security token (combined smart card/usb reader) for my business that works on: Windows 7 x64 OS X 10.6.x x64 Ubuntu Linux (64 or 32 bit, 10.04 or 10.10, I can bend based on possible tokens) Functionality I need is: Login authentication Authentication for whole-disk encryption (in Linux/Windows, Mac is flexible here) Signing/encryption using PGP and x.509 certificates RSA-2048 key-capable (1024 not good enough.) I can manage the certificates myself Open source middleware/drivers (not necessarily FOSS, just source available. Can flex on this, I just want to be able to audit the code. OpenSC-compatible on Linux would be great.) Is there any token that can do all of this? Or would I need multiple ones to accomplish this? Or do I need to look at smart cards and readers to get this? I have been researching this for a while and have had a heck of a time even getting accurate information about products. Also, I am in the USA, and it appears that EU export laws prevent me from buying from there, so those vendors are out. I was looking at Feitian tokens from Gooze, but since they are in France I can't buy.

• Router as primary DNS server, Server as alternate? (or vice versa)

  - by Jakobud

  We have a very small business network, with a typical cable modem hooked into a DD-WRT router. We also run a basic CentOS server that does a variety of things, including acting as the primary DNS server for the office. The reason we need an internal DNS server is because we do a lot of internal web development and use the DNS server to add/remove various local network URLs for internal website testing (like www.testsite.com.local). It's very important for us to be able to add/remove URL aliases easily to the DNS. The problem with this setup is that if we ever need to restart the CentOS server or take it offline for upgrades or whatever, then internet access for all computers on the network is lost. That's because each computer relies on that DNS server to access the Internet I guess? The router is online all the time and very very rarely has to be restarted. It would be nice if we could setup my router to be the primary DNS server but still be running DNS on my server. So we could still add my local testing website URLs to the DNS server in CentOS, but be able to also take down the CentOS server without loosing Internet access on the network. How would this be setup? Would I simply need to add both router + server IP addresses to each computer's IP settings? Is the router primary DNS and server secondary DNS server? Or vice versa? Or can one of the two serve as a fallback for the other? What (if anything) needs to be configured on both the router and server in order for them to recognize that the other DNS server exists on the network? Does anyone have any newb-friendly resources for setting up something like this?

• Experience with asymmetrical (non-identical hardware) SQL Server 2005 / Win 2003 cluster

  - by user24161

  I am reasonably good at dealing with SQL Server clusters; I am wondering if folks have experience, good or bad, using a mix of different models of servers from the same vendor in one SQL 2005 cluster. Suppose: I have one more powerful, more RAM, more shizzle box and one less powerful, less memory, less shizzle box bound together in a 2-node cluster. These would be HP DL380 and 580 machines (not that it should matter) I understand AND automate the process of managing memory for each SQL instance, so there's no memory contention when SQL instances fail over. Basically I am thinking a CLR proc will monitor the instances and self-regulate memory caps on each instance, so that they won't page or step on one another. I get the fact the instances might be slower and or under memory pressure if they share a "lesser" node, and that's OK. The business can deal with a slower instance in a server-problem scenario. Reasonable? Any "gotchas" to watch out for? More info 10/28: doing some experiments with a test cluster I find that reconfiguring max/min memory is OK PROVIDED the instance isn't already under memory pressure. If I torture the system with a huge query that demands a big chunk of RAM, and simultaneously adjust the memory allocation to a smaller value than what is being actively used, it's possible to run the instance out of memory and have it halt and restart itself (unhappy situation). Many ugly out-of-memory messages in the error log, crashing, burning... It's an extreme case, but good to know. Seems, then, that it would only be really safe to set this on startup of the instance, as in have a startup script that says "I am on node1, so my RAM settings are X or I am on node two, so they are Y," like this: http://sqlblog.com/blogs/aaron_bertrand... Update: I am testing a SQL Agent + PowerShell solution described in more detail here.

• Network bandwidth usage dashboard?

  - by SkippyFlipjack

  I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)

• Choosing local versus public domain name for Active Directory

  - by DSO

  What are the pros and cons of choosing a local domain name such as mycompany.local versus a publicly registered domain name such as mycompany.com (assuming that your org has registered the public name)? When would you choose one over the other? UPDATE Thanks to Zoredache and Jay for pointing me to this question, which had the most useful responses. That also led me to find this Microsoft Technet article, which states: It is best to use DNS names that are registered with an Internet authority in the Active Directory namespace. Only registered names are guaranteed to be globally unique. If another organization later registers the same DNS domain name, or if your organization merges with, acquires, or is acquired by other company that uses the same DNS names, then the two infrastructures cannot interact with one another. Note Using single label names or unregistered suffixes, such as .local, is not recommended. Combining this with mrdenny's advice, I think the right approach is to use either: Registered domain name that will never be used publicly (e.g. mycompany.org, mycompany.info, etc). Subdomain of an existing public domain name which will never be used publicly (e.g. corp.mycompany.com). The "never used publicly" part is a business decision so its probably best to get sign off from those in the company authorized to reserve domain names and subdomains. E.g. you don't want to use a registered name or subdomain that the marketing dept later wants to use for some public marketing campaign.

• Best way to restrict access to a folder in Dropbox

  - by Joe S

  I currently run a business with around 10 staff members and we currently use Dropbox Pro 100GB to share all of our files. It works very well and is inexpensive, however, I am taking on a number of new staff and would like to move the more sensitive documents into their own, protected folder. Currently, we all share one Dropbox account, I am aware that Dropbox for teams supports this, but it is far too expensive for us as a small company. I have researched a number of solutions: 1) Set up a new standard Dropbox account just for use by management, which will contain all of the sensitive documents, and join the shared folder of the rest of my team to access the rest of the documents. As i understand it, this is not possible with a free account, as any dropbox shared folder added to your account will use up your quota 2) Set up some sort of TrueCrypt container, and install TrueCrypt on each trusted staff member's machine, and store the documents inside that. Would this be difficult to use? I'd imagine the sync-ing would not work so well as the disk would technically be mounted at the time of use and any changes would be a change to the actual container rather than individual files. I was just wondering if anyone knows a way to do this without the drawbacks outlined above? Thanks!

• How and where do you manage your domain names?

  - by Saif Bechan

  In the past several years doing web development I often times needed to buy new domain names. I changed registrars a lot also so over the years I have multiple domain names scattered over different registrars all over the world. Now I want to bring a little structure into my business, and I am at the point that I want to be able to have easy control over my domain names in a convenient way. Does anyone have an idea on what the best way is to give structure on this. I have made some suggestions maybe you can comment on them for me. 1) Just leave it as it is I can leave everything as it is. To make adjustments I have to log into different panels, and for some registrars I have to email the changes. 2) Transfer all the domains to one registar This will cost a lot, about 10 usd per domain name. But if I can find a registar where I have full control over DNS this is worth looking at. Can you give me some comments on how you are doing things now. Maybe also which registrar you prefer on doing things.

• Windows xp blinking under score after bios

  - by heyjoe

  so this is for an older pc I have to repair for a friend. The pc has an hdd of about 60 something gb, It uses win xp and let's say 60-70% of the boots it hangs on showing only an underscore bilking line after bios screen, rest of the times it boots fine or the computer shuts down on xp loading screen. Sometimes if you let it alone while the underscore is blinking, it will boot after a while, like a few minutes, some times it won't boot at all even if you give him more time, like one hour. When it boots successfully the pc seems to work fine. I think it's a bad hard disk and i'm about to suggest buying a new one and switching it but I don't have enough experience and i would hate making him buy a new hdd and not solving the problem. anyone has any tips? I know there are other topics about blinking underscores or cursors while xp is booting but the issues about the pc shutting itself down or sometimes booting really freaks me out. Can't format everything and re install until about 10 days from now, cause the dude has some program for his business on this pc and I have to migrate it when the next computer arrives, however he needs to use it until then. so please advise, thx.

• How many connections are allowed to a Windows 7 Home Premium shared folder or printer?

  - by lcbrevard

  I have a client who runs a small business with 4 desktop systems, two of which are inexpensive [ The XP Pro system is currently being used as a file "server" for time sheets and QuickBooks data. It also shares an HP ink jet printer. The client wishes to decommission this system because (1) it's ugly [it is] and (2) it uses too much power [it does]. If we share a folder on one of the Windows 7 Home Premium systems will there be a problem connecting to it with up to 3 other computers? What about the printer sharing? I vaguely remember seeing that Windows 7 is less usable for "server" purposes and has severe restrictions on the number of clients. But I cannot seem to find those numbers. In my own network (over 12 systems) we have no problem sharing from Windows 7 Ultimate to a few other systems where needed. I am embarrassed that I cannot seem to find the answer to this in a couple of days of searching. I can do an anytime upgrade of one of these systems to Pro if that would improve the ability to share from it. I am not able to convince the client to put a "real server" into their network.

• Determine which user initiated call in Asterisk

  - by adaptive

  I had the following code in my extensions.conf file: [local] exten => _NXXNXXXXXX,1,Set(CALLERID(name)=${OUTGOING_NAME}) exten => _NXXNXXXXXX,n,Set(CALLERID(num)=${OUTGOING_NUMBER}) Now I want to change this code to set the CallerID and number based on the user/extension that is making the call. In fact I have four(4) users/extensions in my sip.conf and only one of them (the one I use for business) is supposed to send a different caller id/number. Everything is in the same context (for simplicity) since all lines need to be able to pick up an incoming call. The only difference is when line1 needs to make a call, it has to send a different caller id/number and use a different provider. This is what I have so far: [local] exten => _NXXNXXXXXX,1,Set(line=${SIP_HEADER(From)}) exten => _NXXNXXXXXX,n,Verbose(line variable is <${line}>) exten => _NXXNXXXXXX,n,Set(CALLERID(name)=${IF($[ ${line} = line1 ]?${COMPANY_NAME}:${FAMILY_NAME})}) exten => _NXXNXXXXXX,n,Set(CALLERID(num)=${IF($[ ${line} = line1 ]?${COMPANY_NUMBER}:${FAMILY_NUMBER})}) exten => _NXXNXXXXXX,n,Dial(${IF($[ ${line} = line1]?SIP/${EXTEN}@${COMPANY_PROVIDER}:SIP/${EXTEN}@${FAMILY_PROVIDER})}) I really don't know if this is correct and I'm afraid to commit these changes to my extensions.conf before validating. Any help will be greatly appreciated.

• No internet through a web browser but Skype still works

  - by kim3er

  We get our office broadband through a BT Business Broadband WiFi router. We have a mixture of macs and windows PC/laptops connecting to it at any one time. All devices are able to connect to the wireless signal with pretty much full signal. However, only two computers (one windows, one os x) are able to consistently connect to the internet. The other three (one windows, two os x), while they can always connect to the wifi, exhibit one of three characteristics. No internet at all. Programs like Skype work, but no internet through a browser. Internet works, but with intermittent lag when switching between different sites. I'm assuming while trying to resolve different addresses. Ignoring point 1 for moment, my gut is telling me DNS. It is an up to 20MB line that usually gets to between 13MB and 15MB downstream. The router is capable of dealing with the amount of wireless devices that we're throwing at it. Has anyone got any suggestions for how I might further diagnose this problem (preferably in OS X)?

• SQL Server: Network pauses after installing cheap SATA card: Is there a solution?

  - by samsmith

  At the risk of being assigned to the "bad DBA" club... I did something desperate, and may have to undo it. Problem: After installing a low cost eSATA board, my SQL Server is intermittently unresponsive (seemingly when there is a lot of IO to the eSATA drive). Questions: 1) Is there a solution to the intermittent unresponsiveness that allows me to keep the eSATA in place? 2) Whether or not (1==true): What is a decent, low cost way to add 1-3 TB storage to SQL for non-critical SQL DBs? Detail: Our SAN is full, and expanding it is costly and will take a month. I have a pressing need to add 1-3 TB for some development DBs (e.g. not mission critical; data loss is OK). As a bandaid, I threw a $20 eSATA PCI board in the Dell 1950 server, and attached an external 2TB eSATA drive. This seemed to work fine, but I notice that our production SQL DBs, and even remote desktop, now experience network "pauses" that they never did before (with both SQL client apps and remote desktop throwing "networking problem" errors). This SQL Server has lots of memory, and runs an instance of SQL 2005 (where all line of business apps reside) and an instance SQL 2008 (for development db's). SQL Server RAM has been appropriately configured, and this setup has run great for years. The server is: Dell 1950 Win2003 x64 14GB RAM PERC controller, 2 mirrored hd's internal Dell SAN over gbit ethernet, dual homed 2 PCIx slots (1 used by NIC for SAN, 1 now in use for eSATA board) Thank you for suggestions!

• OSX server setup suggestions

  - by Tom

  I am looking into the possibility to setup an OSX server for my employees, and would like some input on what is the best approach to meet my needs, and perhaps some suggestions if I am moving in the wrong direction. I am thinking of a Mac Mini OSX server, and are not sure if my needs will be met, and what possibilities are out there. I want these capabilities: - Groups/Users managed on server - Shared folders and private folders for users/groups - Access to activated services - Server hosting software for the users (developing tools ++) - Similar to Windows Terminal Server - Virtual desktop environment (both local and over internet/VPN) - Possible to access trough Mac and Windows The reason I am looking at OSX server is that my employees almost only work in OSX environment, and I want to offer the capabilities to logon to the server trough some kind of terminal software, and have full access to their work OSX environment and software on their mac or pc, from anywhere they might be. Instead of having to have multiple setups and need for spending alot of time installing and setting up needed software on every client. This is a small business, where some work on local network, and others from the internet, preferably trough VPN. But a terminal server solution, that are fast and easy to manage would be perfect for our needs. So if anyone have any experience with a similar setup, please let me know what you did, and your experiences with your setup.

• ZFS Data Loss Scenarios

  - by Obtuse

  I'm looking toward building a largish ZFS Pool (150TB+), and I'd like to hear people experiences about data loss scenarios due to failed hardware, in particular, distinguishing between instances where just some data is lost vs. the whole filesystem (of if there even is such a distinction in ZFS). For example: let's say a vdev is lost due to a failure like an external drive enclosure losing power, or a controller card failing. From what I've read the pool should go into a faulted mode, but if the vdev is returned the pool should recover? or not? or if the vdev is partially damaged, does one lose the whole pool, some files, etc.? What happens if a ZIL device fails? Or just one of several ZILs? Truly any and all anecdotes or hypothetical scenarios backed by deep technical knowledge are appreciated! Thanks! Update: We're doing this on the cheap since we are a small business (9 people or so) but we generate a fair amount of imaging data. The data is mostly smallish files, by my count about 500k files per TB. The data is important but not uber-critical. We are planning to use the ZFS pool to mirror 48TB "live" data array (in use for 3 years or so), and use the the rest of the storage for 'archived' data. The pool will be shared using NFS. The rack is supposedly on a building backup generator line, and we have two APC UPSes capable of powering the rack at full load for 5 mins or so.

• imagecreatefromjpeg() stops working after server upgrade

  - by John Conde

  We have a server located at a local company's place of business running Solaris/Apache/PHP. They recently did an update to Solaris, Apache, and PHP (security update patches, etc.). Unfortunately it has caused the image manipulation portion of our software to break. imagecreatefromjpeg() is now generating the following error: Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: '/path/to/file/filename.jpg' is not a valid JPEG file in /path/to/file/Image.class.php on line XX No PHP code was changed during the server upgrade and it was fully functional before the software upgrades. I checked the files being passed to imagecreatefromjpeg() and they are indeed valid (they open successfully in both image editing software and in my browser). I checked the permissions of the directory from which the files are being opened and they do have read permission. GD library is enabled. I'm not sure what else I can check. Based on the scenario above I am guessing something changed in the software but I don't know what it could be. PHP was version 5.2.5 and is now 5.2.13. I appreciate any guidance as to what could be cause of this issue.

• Display on secondary video card (Nvidia 8400 GS): horrible refresh, bogs system

  - by minameismud

  This is my work computer, but it's a small shop. We do business software development. The most hardcore thing we create is some web animations with html5 and fancy javascript/css. The base machine is a Dell Precision T3500 - Xeon W3550 (3.07GHz quad), 6GB ram, pair of 500GB harddrives, and Win 7 x64 Enterprise SP1. My primary video card is an ATI FirePro V4800 1GB in a PCIe slot of some speed driving a pair of 23s at 1920x1080 through DisplayPort-HDMI adapters. The secondary card is an NVidia GeForce 8400GS in a PCI slot driving a single 17" at 1280x1024 through DVI. On either of the 23" monitors, windows move smoothly, scroll quickly, and are generally very responsive. On the 17", it's slow, chunky, and when I'm trying to scroll a ton of content, Windows will occasionally suggest I drop to the Windows Basic theme. I've updated drivers for both cards, and I've gotten every Windows update relating to video. Specifically: ATI FirePro Provider: Advanced Micro Devices, Inc Date: 6/22/2014 Version: 13.352.1014.0 NVidia 8400 GS Provider: NVIDIA Date: 7/2/2014 Version: 9.18.13.4052 Unfortunately, new hardware isn't really an option. Is there anything I can do software-wise to speed up the NVidia-driven monitor?

• WPF ToggleButton changing image depending on state

  - by mack369

  I would like to use ToggleButton in following way: There are 5 different images and each of them should be displayed depending on current state: button disabled button enabled, unchecked button enabled, unchecked, pointed by mouse cursor button enabled, checked button enabled, checked, pointed by mouse cursor I've found a simple example with two images on http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/28c36bd2-2ef7-4232-9976-2a0967140e32 , but how to change the image depending on "checked" property? The second question: how can I avoid creating different styles for each button in my application? I'm using about 20 different buttons and each of them has different set of icons. So far I'm using only one icon, below my code. Is it possible to have common code (style and template) and to define the source of images in section where I want to create button (like in section 3 of my code)? <ControlTemplate x:Key="ToggleButtonTemplate" TargetType="{x:Type ToggleButton}"> <Grid> <Border x:Name="ContentBorder" CornerRadius="4" BorderBrush="Transparent" BorderThickness="1" Background="{DynamicResource ButtonOff}"> <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsChecked" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonDisabled}"/> <Setter Property="Foreground" Value="{DynamicResource BorderDisabled}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> <Style x:Key="ToggleButtonStyle" TargetType="{x:Type ToggleButton}"> <Setter Property="Width" Value="64" /> <Setter Property="Height" Value="64" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Template" Value="{DynamicResource ToggleButtonTemplate}" /> </Style> <ToggleButton IsChecked="{Binding Path=IsLectorModeEnabled}" Command="{Binding CmdLector}" Style="{DynamicResource ToggleButtonStyle}"> <Image Source="{DynamicResource LectorImage}" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="None" /> </ToggleButton>

• Applying ServiceKnownTypeAttribute to WCF service with Spring

  I am trying to apply the ServiceKnownTypeAttribute to my WCF Service but keep getting the error below my config. Does anyone have any ideas? <object id="HHGEstimating" type="Spring.ServiceModel.ServiceExporter, Spring.Services"> <property name="TargetName" value="HHGEstimatingHelper"/> <property name="Name" value="HHGEstimating"/> <property name="Namespace" value="http://www.igcsoftware.com/HHGEstimating"/> <property name="TypeAttributes"> <list> <ref local="wcfErrorBehavior"/> <ref local="wcfSilverlightFaultBehavior"/> <object type="System.ServiceModel.ServiceKnownTypeAttribute, System.ServiceModel"> <constructor-arg name="type" value="IGCSoftware.HHG.Business.UserControl.AtlasUser, IGCSoftware.HHG.Business"/> </object> </list> </property> Error thrown by a dependency of object 'HHGEstimating' defined in 'assembly [IGCSoftware.HHG.WebService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null], resource [IGCSoftware.HHG.WebService.Resources.Spring.objects.xml] line 46' : '1' constructor arguments specified but no matching constructor found in object 'System.ServiceModel.ServiceKnownTypeAttribute#25A5628' (hint: specify argument indexes, names, or types to avoid ambiguities). while resolving 'TypeAttributes[2]' to 'System.ServiceModel.ServiceKnownTypeAttribute#25A5628' defined in 'assembly [IGCSoftware.HHG.WebService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null], resource [IGCSoftware.HHG.WebService.Resources.Spring.objects.xml] line 46' Description: An unhandled exception occurred during the execution of the current web request.

• C# and WUAPI: BeginDownload function

  - by Laurus Schluep

  first things first: I have no experience in object-oriented programming, whatsoever. I created my share of VB scripts and a bit of Java in school, but that's it. So my problem most likely lies there. But nevertheless, for the past few days, I've been trying to get a little application together that allows me to scan for, select and install Windows updates. So far I've been able to understand most of the reference and with the help of a few posts around the internet and I'm now at the point where I can select and download updates. So far I've been able to download a collection of updates using the following code: UpdateCollection CurrentInstallCollection = (UpdateCollection)e.Argument; UpdateDownloader CurrentDownloader = CurrentSession.CreateUpdateDownloader(); CurrentDownloader.Updates = CurrentInstallCollection; This is run in a background worker and returns once the download is done. It works just fine, I can see the updates getting downloaded on the file system but there isn't really a way to display the progress within the application. To do such a thing, there is the IDownloadJob interface that allows me to use the .BeginDownload method of the downloader (UpdateSession.CreateUpdateDownloader)...i think, at least. :D And here comes the problem: I have now tried for about 6 hours to get the code working, but no matter what I tried nothing worked. Also, there isn't much information around on the internet about the .BeginDownload method (or at least it seems that way), but my call of the method doesn't work: IDownloadJob CurrentDownloadJob = CurrentDownloader.BeginDownload(); I have no clue what arguments to supply...I've tried methods, objects...to no avail. The complete block of code looks like this: UpdateCollection CurrentInstallCollection = (UpdateCollection)e.Argument; UpdateDownloader CurrentDownloader = CurrentSession.CreateUpdateDownloader(); CurrentDownloader.Updates = CurrentInstallCollection; IDownloadJob CurrentDownloadJob = CurrentDownloader.BeginDownload(); IDownloadProgress CurrentJobProgess = CurrentDownloadJob.GetProgress(); tbStatus.Text = Convert.ToString(CurrentJobProgess.PercentComplete); I've found one source on the internet that called the method with .BeginDownload(this,this,this), which does not report any error in the code editor but probably won't help with reporting as it is my understanding, that the arguments supplied are the methods that are called when the described event occurrs (progress has changed or the download has finished). I also tried this, but it didn't work either: http://social.msdn.microsoft.com/Forums/en/csharpgeneral/thread/636a8399-2bc1-46ff-94df-a58cebfe688c A detailed description of the BeginDownload method: http://msdn.microsoft.com/en-us/library/aa386132(v=VS.85).aspx WUAPI Reference: Unfortunately I'm not allowed to post the link, but the link to the BeginDownload method goes to the same place. :) I know, it's quite a bit to ask, but if someone could point me in the right direction (as in which arguments to pass and how), it'd be very much appreciated! :)
