Hi.. 
I am new for Asp.Net Ajax. I have developed the Demo Application using asp.net Ajax Beta 2. I just created the Grid On Page with
<
asp:ScriptManager ID = "SM1" runat ="server"/>
<asp:UpdatePanel ID = "UP1" runat = "server" UpdateMode ="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID ="btnSearch" />
</Triggers>
<ContentTemplate>
Grid with Page and Sord option
</ContentTemplate></asp:UpdatePanel>
It is working perfectly on My Machine (On which it was developed with XP Professional, VS2005). I tested it on Different Machine it was also XP Professional with .Net Framework 1.1 and 2.0 (Installed from Microsoft Downloads) and didn't Install Asp.net Ajax Beta2 on test machine, all dll related to Ajax are cpoied in bin folder. It worked again properly with out any error. 
But when I upload it on Win 2003 server (installed .Net Framwork 2.0 on it before upload the Application) it loads the Grid properly but gives the Error 'Sys' is Undefined and Ajax do not work
.
I tried some solutions available on Net but unable to resovle this problem. Is this problem is related with Win 2003 server or I have to change My code. One more thing I Copied all Ajax dll into bin folder didn't Install ASP.Net Ajax Beta 2 on Win 2003 server.
Please guide what I do to sole this problem.
