I am using the following dotfuscator task:

<Import Project="$(MSBuildExtensionsPath)\PreEmptive\Dotfuscator\4.0\PreEmptive.Dotfuscator.Targets" />

The build machine has dotfuscator professional installed. Its fully functional and works fine when used manually.

Kindly help in this problem.

This is usually caused by the build service being run under a different account. Dotfuscator requires acceptance of the EULA during it’s initial execution for each user account it runs under.

You can log into the build server using the account that your build is using, run Dotfuscator and accept the EULA. Once you have done that future executions under that account will function just fine.

If you are unable to log in to the build server with the build service credentials PreEmptive technical support can provide you with an alternate method to work around this. You can contact support at [e-mail] or file a support ticket directly at http://preemptive.com/support .
