I have a situation where I would like to deploy the MDAC 2.7 Sp1 refresh to 400 systems using SMS. The network is NT 4 Server DC's (no active directory). I would like this update to have no user interaction and be hidden. Due to security measures in place on the network, the users have to be logged on for the update to roll out. I have searched Technet for switches to use with the MDAC_type.exe but I haven't been able to find any. Does anyone have any ideas on how I can accomplish this task
