After you install the Microsoft .NET Framework Service Pack 1 (SP1), the Submit button on Microsoft ASP.NET pages may not work. You do not receive any error messages.
This problem occurs because client-side script files that are in the Web site are not synchronized with the .NET Framework 1.1. The PostBack event on client-side validation is stopped.
To resolve this problem, install the client-side scripts to the Aspnet_client subfolder of each Microsoft Internet Information Services (IIS) site folder. To do this, click Start, click Run, type the following command in the Open box, and then click OK:
The aspnet_regiis.exe –c command will not work if the Aspnet_client subfolder under one of the Web sites is marked as read only. The most common cause for the subfolder to be marked as read only is that the subfolder is under source control. If the command fails, make sure that the Aspnet_client subfolder is not marked as read only and is not under source control. When the command fails, you receive an error message that resembles the following:
80070005 make sure that you are an administrator to run this program.
Note You may receive this error message even though you have NTFS permissions to the folder.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.
Important This symptom of the PostBack event not being raised and the Submit buttons not working can also occur when you have multiple load-balanced Web servers and the .NET Framework 1.1 SP1 has not been installed on all servers. Verify that the service pack is correctly installed on all servers.
