I tried to use validation in asp.net 2.0 with the following code.

<%@ Page Language="c#" %>
<html>
<body>
<form runat="server">
<asp:TextBox ID="abc" runat="server">
</asp:TextBox>
<asp:RequiredFieldValidator ControlToValidate="abc"
runat="server"></asp:RequiredFieldValidator>
<asp:LinkButton runat="server">click</asp:LinkButton>
</form>
</body>
</html>

I got the javascript error:
"Error: WebForm_DoPostBackWithOptions is not defined
Source File: javascript:WebForm_DoPostBackWithOptions(new
WebForm_PostBackOptions("ctl02", "", true, "", "", false, true))"

Then I view source and found script tags loading external javascript files.

I tried to load it directly in the browser and it showed me this error.

URL:
http://localhost/WebResource.axd?d=CRPh045yFpljm8l46VDATQ2&t=632664526791296187

ERROR:
System.Security.Cryptography.CryptographicException: Padding is invalid and
cannot be removed.

I googled but I cannot find an answer.

I would really appreciate if anyone could help. Thanks!!!

Is this on a web farm by any chance?

Nope, this is not on a web farm.

There is no compression enabled and the error appears on all the
workstations. OS is Windows XP.

I am receiving the same error on my production server, but not on my
development machine. Were there any solutions posted to this problem?

Update: I was able to solve my own problem. I am using a third party
product on my Web Server called SecureIIS (by eeye.com). When I went into
SecureIIS and disabled the security for the website in question, my
JavaScript / WebResource.axd - 404 error went away, re-securing the site
brought the error back. Feeling that my SecureIIS program was unhappy with
the fact that the WebResource.axd file didn't physically exist in the root
folder, I went ahead and created a blank text file and named it
"WebResource.axd". No more errors.

Hope this might help someone.

I tried your solution. However the problem still exists after I created a
blank file with the name "WebResource.axd" in the webroot.

The WebResource.axd is a handler in 2.0 that serves specific client code. It
does not physically exist and you should not add it manually.
