Selenium times out / throws Exception when run in CCNET as a service - selenium

Question

I'm currently working on wiring up Selenium tests to be run by CCNET which runs as a service in our build server.
This is my Project.build file:
<Target Name="AutomationTests">
<Message Text="~~~~~~~~~~~~~~~~$(HARD_NEW_LINE)" />
<Message Text="cmd.exe /interactive /c $(MSBuildProjectDirectory)\Nunit.bat $(SourceFolder)\Project.Web.UI.Automation\bin\Release\Project.Web.UI.Automation.dll"/>
<Exec Command="cmd.exe /interactive /c $(MSBuildProjectDirectory)\Nunit.bat /run:Project.Web.UI.Automation.Test.login $(SourceFolder)\Project.Web.UI.Automation\bin\Release\Project.Web.UI.Automation.dll" ContinueOnError="true" />
</Target>
Note : I resorted to run Nunit from a batch file following the advice in this post.
This is my CCNET.config file:
<msbuild>
<executable>C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe</executable>
<workingDirectory>C:\Projects\Project\AutomationUpdate\</workingDirectory>
<projectFile>Project.build</projectFile>
<buildArgs>/p:Configuration=Debug</buildArgs>
<targets>AutomationTests</targets>
<timeout>1800</timeout>
<logger>C:\CCNET\server\ThoughtWorks.CruiseControl.MSBuild.dll</logger>
</msbuild>
My problem is that, even though Nunit starts up (I can see it's output in the MSBUILD log), Selenium is throwing a timeout exception. This is an excerpt from the build log as seen in CCNET.

Anything I'm doing wrong here?
EDIT :
The previous error was due to an outdated Selenium driver. Now we're getting a different Exception:
SetUp : OpenQA.Selenium.WebDriverException : An error occurred while connecting to Firefox
----> System.IO.IOException : The directory is not empty.

The same code runs perfect when run under CCNET console. Any ideas?

Answer 1

probably a security problem, or a 'user interactive one'
since ccnet runs as local system, it does not have a real 'home' folder.
so probably it can not find the firefox exe, did you specify a path to it?
or it may not access the path
there are a few things you can do :
run ccnet service as the same user you do interactively
alter the security of the folders, so that local system may access them
option 1 is the easiest :-)

Answer 2

Seems my requirement cannot be met by CCNET after all. This is a technical impossibility. We chose to go with another CI server.
