We have a large number of Win2k3 boxes running IIS 6. They all run identical codebases. On only two of the machines, we have a simple scenario where when a form posts back to itself the viewstate is truncated, or it appears to be. All of these
boxes are in a farm configuration.
Things I've checked on these machines when compared to other "working" machines:
IIS setup appears to be the same - gone through page-by page and compared everything.
app-level web.config files are identical
machine-level web.config files are identical
machine.config files are identical
codebase is identical.
I wrote a simple page to test this:
viewstate_test.aspx:
<%@ Page Language="C#" AutoEventWireup="true" trace="true" CodeBehind="viewstate_test.aspx.cs" Inherits="WebApplication1.viewstate_test" %>

<body>
<form id="form1" runat="server">

<asp:TextBox ID="TextBox1" runat="server">testvalue</asp:TextBox>
<br />
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br />
<asp:CheckBox ID="CheckBox1" runat="server" Checked="True" Text="CB1" /><br />
<asp:CheckBox ID="CheckBox2" runat="server" Text="CB2" /><br />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<br />
<br />
<asp:Label ID="Label1" runat="server" Text="ViewState Keys Count= "></asp:Label>
<asp:Label ID="lblViewState" runat="server"></asp:Label></div>
</form>
</body>

if (IsPostBack)
{
lblViewState.Text = ViewState.Count.ToString();
}
}
}
}
Viewstate on the "good" machine is:
/wEPDwULLTE5MTE1Njg1NDEPZBYCAgMPZBYCAg0PDxYCHgRUZXh0BQEwZGQYAQUeX19Db250cm9sc1JlcXVpcmVQb3N0QmFja0tleV9fFgIFCUNoZWNrQm94MQUJQ2hlY2tCb3gytQ77ey6g63AYTBfWWEx/xpnW3oY=
Viewstate on the "bad" machine is:
/wEPDwULLTE5MTE1Njg1NDFkGAEFHl9fQ29udHJvbHNSZXF1aXJlUG9zdEJhY2tLZXlfXxYCBQlDaGVja0JveDEFCUNoZWNrQm94Mmd3mL/ZR16BJ9WOc9ByTG/p+EfV
I'm at a bit of a loss on this one. Anyone have any ideas?
