I am having issues mapping printers via Group Policy Preferences. When I take away the "everyone" group from the security tab the printers will not map (using User Preferences). As long as the member is in the security group it can still access and print via \\Printserver\printer but in the application log I get this error "Group Policy object did not apply because it failed with error code '0x80070005 Access is denied.' This error was suppressed.". If I go to the security settings on the Printserver (Server 2003) and give the "everyone" group print access it maps correctly.
I am testing on XP SP3 computers with Client Side Extensions installed.
