My website runs on .net 1.1. I have a bunch of forms where I included the asp.net required field validations on several fields. The development server is working fine but the validations stopped working on the production server after Windows security updates were run by our network administrator.
I am pretty sure the windows updates did something because nothing has changed in the application and the development server is perfectly fine. I have checked the IIS and the ASP.NET version hasn't changed. It is still 1.1. What else can I check that has changed?
Please advise. What can I do to fix this?
