Oh by the way since we are on the subjects of ditribution groups. I would just like to ask one more question. Does it matter if you put the contacts in a Global>>Distribution Group or a Domain Local Distribution Group. I've only made distribution groups for internal domain users. I usually just set this to Global Distribution and everything works fine for this scenario. Also is there any other advantage of using security groups in this way other than the fact that you can apply them to objects within the domain and set appropriate security permissions. Thank you again for your assistance.
