need definitions for these Win Services

Hi There,

I am currently writing policies for what services should run on our windows servers and am having a hard time finding documentation for the following services. Any documentation you can point me to (especially a description of what happens if you turn it off) would really be helpful. Here they are:

EnterpriseAdmin Agent & Server, HASP Loader, Independant Management Architecture, MSDTC, PCNet DMI, QuotaAdvisor Server, Reflection Server, SecurityService, Win32SL
