Multiple Windows Authentication options on login after Web App restore

Posted By:      Posted Date: September 02, 2010    Points: 0   Category :SharePoint
Hi I have a question regarding SharePoint Foundation 2010 and backup / restore jobs... I'm doing nightly farm backups using PowerShell: Add-PsSnapin Microsoft.SharePoint.PowerShell Set-location $home Backup-SPFarm -Directory \\same-server\***** -BackupMethod Differential This morning I decided to try and restore a single web application, just to make sure it works. In Central Administration I selected the latest farm backup and then selected the node for the Web Application and choose restore (using option: Same configuration) because it's the same server. Restore process went fine, no failure messages, and I can see that it has restored the content I deleted for testing. BUT when I enter the site. I'm presented with a Login page (that you would see if you have also configured Forms Authentication for the same zone, which I have not) and the drop down box show two options: "Windows Authentication" and "Windows Authentication". Both let me use windows credentials to login so basically the login page is pointless and it wasn't there before. I should note: The Web Application was and is configured to use Claims Based Authentication and for Windows Authentication: Kerberos. Nothing for forms. Default sign in page. And I was never presented with this redundant login page before the restore. Anyone knows why this could be happening and how to solve it?? Than

Forms based users being prompted for windows authentication login for My Sites photos in user lists

Here's an issue I didn't see coming for our forms based authentication users. 

We have a web application extended to an external url to handle forms based authentication for users outside of our domain. Our setup looks like this...

Internal Users/Windows Authentication - moss.domain.com
External Users/Forms Based - mossext.domain.com
My Site for Internal Users - mysites.domain.com

When our forms based users are accessing user lists, or discussion pages that display user pictures, they are getting a windows authentication login for our internal users (mysites.domain.com) who have populated their my site with personal photo.

How do we fix this?

Cannot login with Windows Authentication.


I am using MSSQL 2005 in Windows 7.

I login as 'sa', under security I deleted all the user accounts, including BUILT-IN\ADMINITRATOR and all windows accounts.

Now I could not login to MSSQL using windows authentication, and I have forgotten sa password.

Is there any way to login using windows authentication again?

MS SQL Server 2008 sa account locked out and Windows Authentication login is greyed out



The sa account got locked out and even though mixed mode authentication is enabled. When I select "Windows Authentication" the Username and Password fields are greyed out. The username field contains my current windows logon and the password field is blank. I am logged in with a windows administrator account though I hadnt explicitly added this account to the SQL server sysadmin role.

I have also tried "Run as Administrator" with the SQL server management studio but the problem persists

Please note that SQL server was installed with another windows administrator account. Could this be the reason ? Will it work if I login with the account with which SQL server was installed ?

What Do the Different Printer Options using Windows Mobile Pocket Pc

Select Printer Options:
bullet Printer: Select the printer to print to. Some printer selections work for a variety of printers, such as the "HP PCL" selection which prints to most Hewlett Packard DeskJet, LaserJet and compatible printers.
bullet Port: Select between Infrared, Bluetooth, Network printing and Serial (COM1-COM8). Most Windows CE devices only have Infrared and COM1 and need special attachments to use the other selections. USB printing and printing across an ActiveSync connection to a desktop printer is not supported.
NOTE: On many Pocket PC devices, you CANNOT use the serial and infrared ports at the same time. This means that if your device is connected to your desktop PC using the serial Sync cable, the Infrared port will not work. You must disconnect the serial connection to use Infrared printing.
bullet Color/Mono: Select Monochrome (Black & White) if your printer is not a color printer (or if you wish to print in mono). If your printer has color capabilities AND has a black ink capability, select "4-Color CMYK". If your printer cannot hold both color ink and black ink at the same time, select "3-Color CMY".
bullet Paper Size: Select paper size for use. You can choose "Custom" and then set special paper sizes in the "Custom Paper" Width and Height boxes. For printers that use "roll" paper, you can set a maximum paper height of 22 inches.

Web Matrix + Windows Authentication


I'm curious if its possible to get windows auth working with asp.net webpages/webmatrix.

I've got it published to IIS with windows auth turned on and anonymous/forms/basic turned off.

I'm guessing the WebSecurity Helper probably won't work here but can you access User.Identity.Name etc?

Sorry for the newbie questions, I've only just started working with asp.net ^^,

Using windows authentication to access SQL when using ASP.NET 4.0 via COM+


I am using SQL Server 2008 under windows authentication, front end is ASP.NET which uses COM+ to access database.

COM+ components are configured to run as domain user.

When looking through the logs (SQL Profiler), I can see the login name as the configured identity instead of windows indentity.

I have got Website running under "Intergrated Windows Authentication" and database is running locally on webserver.

Web configure contains entry for <identity impersonate="true"/>.

My connection string is

connectionString="data source=db01\test01;initial catalog=test; integrated security=SSPI;persist security info=False; Trusted_Connection=Yes"

Any ideas?

Windows Forms: Give Your .NET-based Application a Fast and Responsive UI with Multiple Threads


If your application performs any non-UI processing on the thread that controls the user interface, it may make the app seem slow and sluggish, frustrating users. But writing multithreaded apps for Windows has long been restricted to C++ developers. Now with the .NET Framework, you can take advantage of multiple threads in C# to control the flow of instructions in your programs and isolate the UI thread for a fast and snappy user interface. This article shows you how. Also, it discusses the pitfalls of multiple threads and presents a framework for safe concurrent thread execution.
