Occasionally, I need to stop all of the CRM services ( and web site ) so I can perform some type of update.  I got tired of doing this manually, and as an off-shoot of another project, I created a small utility that will start and stop the following CRM-related services:

The CRM Web Site

MSCRMBulkMailService
MSCRMDeletionService
MSCRMWorkflowService
MSCRMFaxRouterService
MSCRMExRouterService

CRM StartStop can be found in the Premium Content section on my company web site.  Registration is required but the utility is free.
