Using Internet Explorer, you are unable to log into the VSA and get error: “Cookies are required for logon. Please enable cookies, then refresh this page before proceeding.”

PROBLEM:

Unable to log into VSA using Internet Explorer (IE). Receive the error > "Cookies are required for logon. Please enable cookies, then refresh this page before proceeding". Other browsers work fine

 

CAUSE:

This is caused by the VSA not being able to detect the browser correctly due to an issue with Microsoft's .NET Framework.

Microsoft has issued a patch to address this issue. 


SOLUTION:

 On the Windows server hosting the VSA, please take the following steps:

Sometimes, the MS Patch does not "cleanup" ASP temp directories, so it is recommended to do the following after installing the patch:

  • Stop IIS
  • Navigate to C:\Windows\Microsoft.NET\Framework\v4.<<some_number>>\Temporary ASP.NET Files  

Delete the contents of that directory (Do NOT delete the folder, just the contents of the directory)

  • Navigate to C:\Windows\Microsoft.NET\Framework64\v4.<<some_number>>\Temporary ASP.NET Files 

Delete the contents of that directory (Do NOT delete the folder, just the contents of the directory)

  • Restart IIS
  • Browse to the login page using IE

 

APPLIES TO:

V7, R8, R9.x

Internet Explorer
