Viglen Omnino group policy issue
We have a problem with our new(ish) viglen omnino III pcs in that the group policy permissions don't apply correctly. On all other PCs in the school, pupils of the school cannot access modify content of the "All Users" folder in documents and settings, however on the omnino III's they can. They've been able to move icons to their desktop meaning that they're no longer there for others to use, of course causing problems. We're sure this isn't the only folder they can access that they shouldn't be able to.
Has anyone else experienced this with Omnino III desktop PCs? We have Omnino II's and they don't have this issue.
