Analysis

The issue was related to reference to System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 which was missing in the GAC. System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 was present, but the version 1.0.61025.0 was missing.

This was true even thought within the configuration of monitoring server it explicitly stated that ASP.NET 2.0 AJAX 1.0 was installed.

 

Resolution

This issue was resolved by installing ASP.NET 2.0 AJAX 1.0, which in turn installed the missing System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 in the GAC.

 

Note: Within the configuration of monitoring server it explicitly stated that ASP.NET 2.0 AJAX 1.0 was installed originally.
