Server Manager

Does anyone know how to run a server manager tool on a NT network with a Windows 2000 Prof. workstation ?

Our Chief Financial Officer runs a company wide Accounting s.w. that from time to time needs to have all users off the accounting s.w. so she can perform some prevented maint. to this s.w. The problem is that she needs to have all users off this program when she is doing this but sometimes users have the program open. Instead of her coming to me, is their a way for her to see who has theprogram open like you can on a NT server through server manager so she can notify whoever has the program open ? this accounting s.w. has administrator limitations to say the least.
