Are you sure you have permissions setup correctly on the shares? Keep in mind GP software assignments process under the machine account. Trying giving explicit access to the "Domain Computers" group and see if that helps. Packages Assigned to Computers with Group Policy Are Not Installed <http://support.microsoft.com/kb/278472> If that doesn't work you may be experiencing a race condition with Group Policy trying to process before the network is up. There are a few things you can try that may help out with that, but since Office is installing okay, I could be wrong. 1. Configure the GpNetworkStartTimeoutPolicyValue setting (KB840669 <http://support.microsoft.com/kb/840669> ) 2. Disable Media Sense for TCP/IP (KB326152 <http://support.microsoft.com/default.aspx?scid=kb;en-us;326152> ) 3. Disable Fast Logon Optimization on Windows XP clients (ie. "Always wait for network at computer startup and logon"). (KB305293 <http://support.microsoft.com/kb/q305293/> ) If that doesn't help either, you should enable logging for both the Application Management CSE <http://support.microsoft.com/kb/246509/> and Windows Installer <http://support.microsoft.com/kb/314852/en-us> . That may give you some more clues as to what is going on. //signed// Jamie R Nelson Systems Engineer Ingenium Corporation 72 CS/SCBNF 405.739.2811 (DSN 339) ________________________________ From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Craig Judd Sent: Wednesday, February 14, 2007 2:45 AM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Installing Applications Fails 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.
