New Post: undeploy and redeploy option is not visible in start menu under the applicaiton

Thanks for your reply. we are using 5.0 version. i mean to say all start->programs->biztalk application. under that i see deploy option. i understood that there is undeploy and redeploy options as such. There should be one configuration file where all these setting to be done.Please can you provide some clue on this.
I see uninstallwizard and installwizard.xml files also there in the deploytools option.
