[ccnet-user] Task exceution failed

[sam]

Currently I am using cc.net1.4.4. After running the build I am getting
Task exceution failed. In dashboard, it is showing me the projects and
their versions but when i click to see their details It says page
cannot be displayed.

Following is copy of my task block

      <tasks>
        <!--MSBuild task to build a .msbuild file that basically
builds a .sln file-->
        <exec executable="C:\cc\test\files\DFiles.bat"/>
        <msbuild>
          <executable>C:\WINDOWS\Microsoft.NET\Framework
\v2.0.50727\MSBuild.exe</executable>
          <workingDirectory>C:\cc\test\code\</workingDirectory>
          <projectFile>Com.Test.sln</projectFile>
          <buildArgs>/noconsolelogger /p:Configuration=Release /
v:diag</buildArgs>
          <timeout>900</timeout>
          <logger>C:\Program Files\CruiseControl.NET\server
\ThoughtWorks.CruiseControl.MsBuild.dll</logger>
        </msbuild>
      </tasks>

Any idea what I am doing wrong.
