  • Microsoft.Web.Administration.ServerManager can't read config sections containing encrypted passwords in applicationHost.config

    - by Dylan Beattie
    I have some sites in IIS7 that are configured to run as domain users (MYDOMAIN\someuser). I'm using the Microsoft.Web.Administration namespace to scan my server configuration, but it's throwing an exception when I hit one of these "impersonator" sites: using (ServerManager sm = new ServerManager()) { foreach (Site site in sm.Sites) { foreach (Application app in site.Applications.Reverse()) { foreach (VirtualDirectory vdir in app.VirtualDirectories.Reverse()) { var config = app.GetWebConfiguration(); foreach (var locationPath in config.GetLocationPaths()) { // error occurs in GetLocationPaths() } } } } } The actual error message is: COMException was unhandled Filename: \\?\C:\Windows\system32\inetsrv\config\applicationHost.config Line number: 279 Error: Failed to decrypt attribute 'password' because the keyset does not exist It appears that IIS is storing the MYDOMAIN\someuser password encrypted in applicationHost.config, which is great in terms of security - but I have no idea how to get the ServerManager to decrypt this. Any tips on how I can either allow ServerManager to decrypt this, or just tell IIS to store the passwords in plain text? This is on IIS7 under Windows 7 RC, by the way.

  • Automated builds of BizTalk 2009 projects using Team System 2008 Build

    - by Doug
    I'm trying to configure automated build of BizTalk 2009 projects using Team Foundation Server 2008. We have a staging server which has BizTalk 2009 installed. I ran the Team Foundation Server Build Setup on this server, and it can build non-BizTalk projects OK. However, BizTalk projects fail to build. I suspected something was amiss when "Deployment" was not a valid build type! I tried copying various things over from a developer PC which has BizTalk and Visual Studio 2008 installed, but still couldn't get it to work. I don't really want to install Visual Studio on the staging server, but without it the "Developer Tools and SDK" option in the BizTalk install is greyed out. I guess I need this in order for BizTalk projects to compile. So, my question is can a BizTalk 2009 server be used as a TFS build agent to build BizTalk projects without having Visual Studio installed. If the answer is no, what's the smallest part of VS that can be installed to get this to work? Thanks in advance.

  • List local administrators with System.DirectoryServices.AccountManagement doesn't retrieve domain us

    - by yajohn
    I'm trying to remotely list members of the local Administrators group. The following code returns only local accounts which are members of the admin group - no domain groups or individual accounts are returned at all (BLAH\Domain Admins or BLAH\yajohn, for instance). Anyone have an idea? Public Function listLocalAdmins(ByVal machinename As String, ByVal creduname As String, ByVal credpass As String) As String Try Dim mctx As New PrincipalContext(ContextType.Machine, machinename, creduname, credpass) Dim lcladmins As GroupPrincipal = GroupPrincipal.FindByIdentity(mctx, IdentityType.Name, "Administrators") Dim pc As PrincipalCollection = lcladmins.Members Dim r As New StringBuilder For Each p As Principal In pc r.Append("Name:->" & p.Name.ToString & vbCrLf) Next Return r.ToString Catch ex As Exception Return ex.Message End Try End Function Thanks for any feedback.

  • Performance problem with System.Net.Mail

    - by Saif Khan
    I have this unusual problem with mailing from my app. At first it wasn't working (getting unable to relay error crap) anyways I added the proper authentication and it works. My problem now is, if I try to send around 300 emails (each with a 500k attachment) the app starts hanging around 95% thru the process. Here is some of my code which is called for each mail to be sent Using mail As New MailMessage() With mail .From = New MailAddress(My.Resources.EmailFrom) For Each contact As Contact In Contacts .To.Add(contact.Email) Next .Subject = "Accounting" .Body = My.Resources.EmailBody 'Back the stream up to the beginning orelse the attachment 'will be sent as a zero (0) byte file. attachment.Seek(0, SeekOrigin.Begin) .Attachments.Add(New Attachment(attachment, String.Concat(Item.Year, Item.AttachmentType.Extension))) End With Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") .Send(mail) End With End Using With item .SentStatus = True .DateSent = DateTime.Now.Date .Save() End With Return I was thinking, can I just prepare all the mails and add them to a collection then open one SMTP conenction and just iterate the collection, calling the send like this Using mail As New MailMessage() ... MailCollection.Add(mail) End Using ... Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") For Each mail in MainCollection .Send(mail) Next End With

    - by Thakkar
    I am unable to access Sharepoint Central Administration. I installed MOSS 2007 successfully on Windows Server 2008 (IIS7 and SQL Server 2005), I launched the admin and got "Cannot connect to the configuration database" error. Application pool is using NetworkService account which has access to SQL Server. I can access the configuration databases through SQL Management Studio. SQL server is on the same machine. Any help, suggestions on how to solve the problem? I am very new to SharePoint.

  • Placing a window near the system tray

    - by user227990
    I am writing a program that needs to set a window just above/below the traybar for gtk. I have tried using the 2 approaches that failed. One was using the gtk_status_icon_position_menu function and placing the window in the point where the user clicks (in the tray bar). The problem is that these solutions work in gnome(Linux) but not in Windows. In Linux they work because the window manager doesn't seem to allow placement of windows in the tray panel, honoring the closest possible. In Windows this doesn't happen and the window can go "out" of the screen which understandably is not desired. With this said i went out for a work around. My idea was to set the window in the location of mouse click and get the x and y coordinates of a normal window placement and with it's size check if it would be within the screen boundaries. If it was not make the correction. I have came up with the functions needed but for some reason the gdk_drawable_get_size(window-window ,&WindowWidth, &WindowHeight) and other similar functions only give the correct size value after the second run of the signal function. The result of the first run is just 1 to both size and width. (I have read the issue of X11 not giving correct results, but i think this is not it) event_button = (GdkEventButton *) event; if (event_button->button == 1) { if (active == 0) { gboolean dummy; gint WindowHeight, WindowWidth, WindowPosition[2]; GdkScreen *screen; gint ScreenHeight, ScreenWidth; dummy = FALSE; gtk_widget_show_all(window); gtk_window_present(GTK_WINDOW(window)); gtk_status_icon_position_menu(menu, &pos[X], &pos[Y], &dummy, statusicon); gtk_window_move(GTK_WINDOW(window), pos[X],pos[Y]); gdk_drawable_get_size(window->window ,&WindowWidth, &WindowHeight); screen = gtk_status_icon_get_screen(statusicon); ScreenWidth = gdk_screen_get_width(screen); ScreenHeight = gdk_screen_get_height(screen); g_print("Screen: %d, %d\nGeometry: %d, %d\n",ScreenWidth, ScreenHeight, WindowWidth, window->allocation.height); gtk_entry_set_text(GTK_ENTRY(entry),""); active = 1; return TRUE; } How can i do what i want in a portable way?

  • .Net User Messaging System

    - by bechbd
    I am wondering if there is a framework out there for .NET to help me with sending messages to users. I would love to be able to write all my messages to a single repository. I would then like to be able to send these messages out to a user based on preferences that they set. e.g. I would like to be able to send a Notification A out to user A via email and text message and send Notification B to user B via SMS and IM. Any thoughts on if something like this exists or would I need to write it?

  • .Net System.Mail.Message adding multiple "To" addresses

    - by Matt Dawdy
    I just hit something I think is inconsistent, and wanted to see if I'm doing something wrong, if I'm an idiot, or... MailMessage msg = new MailMessage(); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); Really only sends this email to 1 person, the last one. To add multiples I have to do this: msg.To.Add("[email protected],[email protected],[email protected],[email protected]"); I don't get it. I thought I was adding multiple people to the "To" address collection, but what I was doing was replacing it. I think I just realized my error -- to add one item to the collection, use .To.Add(new MailAddress("[email protected]")) If you use just a string, it replaces everything it had in its list. Ugh. I'd consider this a rather large gotcha! Since I answered my own question, but I think this is of value to have in the stackoverflow archive, I'll still ask it. Maybe someone even has an idea of other traps that you can fall into.

  • C system calls open / read / write / close problem.

    Hello, given the following code (it's supposed to write "hellowolrd" in a "helloworld" file, and then read the text): #include <fcntl.h> #include <sys/types.h> #include <sys/stat.h> #define FNAME "helloworld" int main(){ int filedes, nbytes; char buf[128]; /* Creates a file */ if((filedes=open(FNAME, O_CREAT | O_EXCL | O_WRONLY | O_APPEND, S_IRUSR | S_IWUSR)) == -1){ write(2, "Error1\n", 7); } /* Writes hellow world to file */ if(write(filedes, FNAME, 10) != 10) write(2, "Error2\n", 7); /* Close file */ close(filedes); if((filedes = open(FNAME, O_RDONLY))==-1) write(2, "Error3\n", 7); /* Prints file contents on screen */ if((nbytes=read(filedes, buf, 128)) == -1) write(2, "Error4\n", 7); if(write(1, buf, nbytes) != nbytes) write(2, "Error5\n", 7); /* Close rile afte read */ close(filedes); return (0); } The first time i run the program, the output is: helloworld After that every time I to run the program, the output is: Error1 Error2 helloworld I don't understand why the text isn't appended, as I've specified the O_APPEND file. Is it because I've included O_CREAT ? It the file is already created, shouldn't O_CREAT be ignored ?

  • Naive question of memory references in Operating system

    - by darkie15
    Hi All, I am learning memory references pertaining to Operating systems and don't seem to get to the crux of understanding it. For example, I am not able to visualize this scenario properly: "A 36 bit address employs both paging and segmentation. Both PTE and STE are 4 bytes each". How are they related? I can guess that this question might be too simple for many. But any help understanding the above basic concept would be appreciable. Regards, darkie15

  • Operating System Widget Side Project

    - by Calpis
    I want to start on a side project and here's my idea: Whenever the user's mouse is pressed down, I want a small ring around the cursor to show up. I'm mainly doing this to learn more about programming and get myself to think outside of work related materials. My questions are: 1) is there a good source I can reference to start a project that deals with something like this? 2) Is visual studio a sufficient software to create such an application? Or would I need some other tool to do this. 3) What language should I choose to do this task? Thanks in advance!

  • Why the “Toilet” Analogy for SQL might be bad

    - by Jonathan Kehayias
    Robert Davis(blog/twitter) recently blogged The Toilet Analogy … or Why I Never Recommend Increasing Worker Threads , in which he uses an analogy for why increasing the value for the ‘max worker threads’ sp_configure option can be bad inside of SQL Server.  While I can’t make an argument against Robert’s assertion that increasing worker threads may not improve performance, I can make an argument against his suggestion that, simply increasing the number of logical processors, for example from...(read more)

  • How To Disable Control Panel in Windows 7

    - by Mysticgeek
    If you have a shared computer that your family and friends can access, you might not want them to mess around in the Control Panel, and luckily with a simple tweak you can disable it. Disable Control Panel with Group Policy Note: This process uses Local Group Policy Editor which is not available in Home versions of Windows 7. Skip down below for the registry hack version that works on Home editions as well. First type gpedit.msc into the Search box in the Start menu and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select Control Panel in the left Column. In the right column double-click on Prohibit access to the Control Panel. In the next window, select Enable, click OK, then close out of Local Group Policy Editor. After the Control Panel is disabled, you’ll notice it’s no longer listed in the Start Menu. If the user tries to type Control Panel into the Search box in the Start menu, they will get the following message indicating it’s restricted. Disable Control Panel with a Registry Tweak You can also tweak the Registry to disable Control Panel. This will work with all versions of Windows 7, Vista, and XP. Making changes in the Registry is not recommended for beginners and you should create a Restore Point, or backup the Registry before making any changes. Type regedit into the Search box in the Start menu and hit Enter. In Registry Editor navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer. Then right-click in the right pane and create a new DWORD (32-bit) Value. Name the value NoControlPanel. Then right-click on the new Value and click Modify…   In the Value data field change the value to “1” then click OK. Close out of Registry Editor and restart the machine to complete the process. When you get back from reboot, you’ll notice Control Panel is no longer listed in the Start menu. If a user tries to access it by typing Control Panel into the Search box in the Start menu… They will get the following message indicating it is restricted, just like if you were to disable it via Group Policy. If you want to re-enable the Control Panel, go back into the Registry and change the NoControlPanel value back to “0” then reboot the computer. This comes in handy if you have inexperienced users working on your machine and don’t want them messing with Control Panel settings.
