MSIs install via Group Policy but not that reliably
Clients: Win XP Server: 2008
We're installing a lot of applications via group policy. In the past, on other networks, I've never had problems with reinstalling 25+ computers simultaniously from one server - even over wireless. It's slow, but I leave them over night and by the next day they're done!
On this network (much larger: 200+ computers) if I try to install even 10-15 some applications will fail to install.
It's not always the same app and not the same computers. Last time I reinstalled a room Bodywise (300MB) failed more than any other app. This time it was IE8, WMP (MSI wrapping an EXE) and Zig Zag Tudors (6MB)!
What's annoying is that Windows thinks the application is installed. There are no errors in the event log and if you try to install the program again, it will bring up the repair/remove dialogue. Normally if an app fails it will keep trying to reinstall it.
I thought it was dodgy networking - in the first room computers took ages to get an IP but in the 2nd room I tried they were getting IPs in 1second and network speed is 80mbps.
Some ideas I've had.
- Load balance accross multiple servers - I've used DFS as path names so we could easily set this up in the future.
- Have packages installed as admin installs - so the cabinet files are extraced on the server rather than compressed in the msi. Does anyone know if this makes any difference?
Anybody got any idea if these might work or a better idea?
