In our scenario we have roaming profiles, but we have the GPO setting enabled to delete these profiles (computer config/admin templates/system/user profile/delete cached copies of roaming profiles set to enabled). This is set at the domain level of the organisation and there is only one domain. This is so that if the profile becomes corrupt there won't be any local remnants of it and we also found that as we're a uni campus with many students logging on to one machine we eventually end up with the hard disk becoming full!
However, if I look on to a machine I still see remnants of users profiles, but I also see folders that are something like %username%.%domainname%.001, %username%.%domainname%.002, %username%.%domainname%.003 where %username% is the username and %domainname% is the domain name. It looks like the folders are incrementing with each log on, which is actually the reverse of what we are trying to achieve! From this I'm assuming that the policy itself isn't working, but we're not getting any clues as to why. There's no event log messages saying that GPO's aren't being applied, no blocking of inheritance, etc. Two of us have been through the AD completely and double checked everything individually and we can't see anything wrong there, so any help would be very much appreciated.
