controller winsrv2003 ,the information bar
require to install active x and after i install it ,the information bar say
that my security setting prevent from running the installed activex (error
code=0x8ddd0004)

but i go to the internet option and open the security seeting of interent
zone and make syre that all activex is allowed also i go to the trusted zone
where i add all the websites of updates and check that security setting allow
