Consider these questions before making a decision: How many and what kinds of users will need access to your system? Are they non-technical people in finance and marketing that only need limited access to certain applications, files, spreadsheets or databases? Do they have access to customer information, company trade secrets or other high-risk data?
As the number of users grows, and the risk level increases, there is less reason to grant admin rights.
Using admin rights to open up your desktops, even if only for logging on to the domain, gives your users rights that you might not want them to have. With these privileges, users can change system resources to add unauthorized software and hardware, open USB ports to allow unauthorized uploading or downloading of data and make changes generally incompatible with the consistency of your enterprise system.
Enterprise desktop use should be based on standards agreed upon for the whole company. Once the setup policy is determined, it should be locked down and kept consistent.
However, it is sometimes necessary to grant admin rights. For example, today many commonly used Windows applications can only be run by those with administrator privileges. Fortunately, Microsoft plans to fix this with the release of the Windows Vista operating system.
