Consider a scenario where you need to label a TFS branch at end-of-day everyday and you missed labelling it yesterday and today there are quite a number of check-ins already committed in the branch. How do you label yesterday’s code base then?
TFS provides a very easy way to label branches and solution to above scenario also exists. Follow the below steps to label the older code base.
- Right-click the TFS branch to be labelled and click on View History. Note the last changeset number at which you want to label the branch.
- Go back to Source Control Explorer and right-click the branch to be labelled. Go to Advanced –> Apply label
- In the drop-down, select Changeset and enter the change set number that you noted down earlier.
- Enter the label name of your choice and then click on create.
Now the TFS branch code base is labelled at the level of the last changeset which we entered. To verify the labelled code, compare the latest version of the code with the labelled code that you just created. There have to be differences and these differences will be that of the check-ins made AFTER the change set noted down above.
Hope this helps!

Consider a particular scenario where sa account gets disabled (by any reason) and windows authentication doesn’t have the rights to connect to the database server; basically windows authentication is not available. In such a case, you will not be able to do much from Sql server management studio to enable sa account again because to do that, you will have to run a query and to run the query, you need to be connected first to the Database. **Deadlock** So what to do?
There is a pretty simple hack for this. You need to edit a particular registry key property’s value. Follow the below steps to enable mixed mode authentication when you’re locked out. However, please note that this could be a potential security risk (note the word ‘hack’ mentioned earlier). Make sure your sa account has a very strong password.
- Open Run (Windows + r) and type regedit. Hit enter. Click OK.
- This opens the Registry editor. Navigate to the registry key
HKLM\Software\Microsoft\Microsoft SQL Server\MSSQL11E.LOCALDB\MSSQLServer\LoginMode
Note: For those who don’t know what HKLM is, HKLM refers to HKEY_LOCAL_MACHINE
—-The text highlighted above in red can change based on what instance name you’re using.
- Change the value of LoginMode to 0x00000002 (2). The value 2 refers to Mixed Mode authentication and value 0x00000001 (1) refers to Windows Authentication. Make sure it is now set to 0x00000002.
- Restart the SQL Server and pc (if required). Now you will be able to connect to the database using sa account.
Hope this helps!

I recently setup an ADFS website on a server and required the site to display the forms authentication page asking for log in credentials whenever the AD was accessed. But every time, I ended up getting the windows authentication pop up instead of the pop up.
After doing some research online, I found that ADFS website always tries to use Windows authentication before trying to use the forms authentication. If forms authentication is used, the log in page is shown.
To make the Forms authentication log in page show up instead of the pop up, follow the below steps:
- Open the physical path of the adfs/ls site. You can do this from IIS manager. Expand the site –> Right-click –> Explore.
- Open the web.config file and locate the <localAuthenticationTypes> tag. This section lists the order in which authentication takes place.
- Comment out all the items except Forms authentication. Alternatively, you can move the “Forms” key to the first of the list. This will make the site to use Forms authentication before Windows authentication.
- Save the web.config file. Try opening the site and the login page should show up as expected.
Hope this helps!

There are many instances where you have to provide a custom account identity to an App pool in IIS. There are also instances where you might have forgotten the password for that account which has to be set as identity for that Application Pool. In such cases, you can use the APPCMD command to retrieve the password for that user. One thing to remember is that there has to be an app pool existing in the machine already which has been assigned that account’s Identity for us to retrieve it’s password. Please note: This can be used for IIS 7 and above.
appcmd is an IIS tool used to manage IIS server. It provides many functions that can be used to manager server related activities like create/configure sites, start/recycle/stop app pools, etc.
Retrieve Password of an App Pool identity account:
- To retrieve password for an app pool identity account, open the command prompt in administrative mode.
- Navigate to C:\System\Windows32\inetsrv directory. This is the location where appcmd.exe exists.
- Type the below command and press enter.
appcmd.exe list apppool <<app_pool_name>> /text:*
For example: I have an app pool in my IIS named SampleAppPool which has been assigned a particular account’s identity whose password I would like to retrieve. So I would enter the below command in command prompt.
Press enter and the result will be as shown below. Due to security reasons, I have removed the username and password from the image but trust me, it shows the username and password there.Hope this helps!
I had to install Windows Identity Foundation SDK in a Windows 2012 R2 server for setting up Claims-based authentication. So I downloaded the SDK and started the installation. Immediately I was shown this error popup.
The cause of the error is apparent – Windows Identity Foundation (WIF, going forward) is not installed in my server.
To install WIF runtime, follow the below steps if you’re using Windows Server 2012
- Open server manager. Click on Add Roles & features.
- Click Next and navigate till the Features section. If you want to know how to navigate through “Add Roles and Features” dialog box, refer to my post here. Make sure you come back to this post once you reach Features section.
- Scroll down and you will find “Windows Identity Foundation”. Select that and click next.
Note: In your case, it will be unchecked and not disabled and available for selection unlike the one shown here in the screen shot below.
- Click next and finish the installation.
This will install WIF Runtime in your server. After this is completed, run the SDK setup file again. This time, WIF SDK will get installed without any issues.
To install WIF Runtime on Windows 8, 8.1:
- In start menu, type “Turn Windows Features On and Off”. Open the dialog box.
- Scroll down and enable Windows Identity Foundation.
- Click OK.
This install WIF Runtime in Windows 8, 8.1.
Hope this helps!
