Hi We have a medium sized Active Directory that has been in place for about 3 yrs, apart from the deployment of the Office Suite against the "domain policy" we have OU's that represent each group of machines and in turn we have associated applications for each department trying to install from these OU's. The office installation succeeds by the way. However it has come to light that these other apps fail to be deployed successfully, the LOG entry says that the "source installation file is not available". So we see that when we reboot a client workstation it says that it is installing the required application, it all appears to go through ok, the log in box finally appears, but yet the deployed application has not been installed. The source files are available at the share location, and all security and rights are available to everyone as read only. Any pointers as to why the apps are failing to deploy would be a huge help, thanks in advance. Craig Judd ICT Network Manager Parkstone Grammar School, Sopers Lane, Poole, Dorset.
