Software Deployment

Recently I have been noticing weird behavior on our workstations on campus. We deploy software through group policy, during startup using Active Directory. We currently deploy 40+ software packages, which includes all most any major productivity software, such as Office, Adobe CS, Macromedia, etc... Our machines start up, goes through the software installation process, and then after 45 mins it will go to the CTRL+ALT+DEL login screen. It usually takes about an hr to install all software, which is not a problem because the machines are only reloaded about twice a month. Once a user logs in, it will finish installing the rest of the software packages that didnt finish before the login screen comes up. This is weird because all the software packages are set to install during startup, not during login. Once the machine finishes installing the software after the user logs in, it will reboot and start running the appropiate startup scripts. Here is how our process is suppose to work...


Reload machine---->Install software----->run startup scripts----->reboot--->login screen

but this is what is happening

Reload machine---->Install partial software----->login screen


Like I said, this is weird because this has only started happening within the last two weeks, and nothing has been changed within our system configuration. Any ideas..... :-/
