hi all If you have UAC enabled and support a win7 client in a domain with remote assistent look at things with uac answer the helper become a black screen. has anybody a workaround (not disable uac)

This issue arises when you use UAC with the Secure Desktop. (default) You can work around on this situation with Group Policies. These policy settings are located in Security Settings\Local Policies\Security Options . When you enable the User Account Control: Allow UIAccess applications to prompt for elevation without using the secure desktop setting and enable the User Account Control: Switch to the secure desktop when prompting for elevation setting, you can remotely approve UAC prompts
