Mikal,
You do not deploy applications via GPO to groups. This is your first
problem! You deploy applications either to user account objects or to
computer account objects which directly reside in the OU ( assuming that we
are talking about this level; it is possible that we are talking about
another level...possibly the Site level? ) to which the GPO has been linked.
You have to make sure that the user account objects ( or computer account
objects, but since you are trying to deploy this to user account
objects.... ) have both the Share and NTFS permissions to the shared folder
in which the .msi file is located.
You have to make sure that you tell Active Directory where the .msi file is
via the UNC method ( \\servername\sharename\file.msi ) and not via a mapped
network drive ( n:\someserver\somefolder\file.msi ).
Now, in reference to my first point: it is possible that you are using
Security Group Filtering. This is - on the Security tab of the GPO itself -
where you would remove the group 'Authenticated Users' from the security and
add your own security group. If you have done this you need to make sure
that this group has both the READ and APPLY GROUP POLICY rights.
What troubleshooting have you done? What would the OS on the clients be?
Also, you need to make sure that your clients are pointing O*N*L*Y to your
internal DNS Servers ( and not to any external DNS Servers - such as your
ISP's ) in their TCP/IP configuration settings.
