Hi, I saw a post saying that using the active directory management pack in combination with Scom gateways doesn't properly work. I tried to monitor remote AD's and indeed I got some security errors. But I can't seem to find information about limitations using the scom gateway server. Does anyone know where I could find this information?

The security issue isn't really any different as in a 1 domain/forest scom environment, only the scom admins would have access to multiple domains/forests. Also the security isn't any different that any other tool that would try to monitor the same things. But agreed you should be aware of this." Tony. edit--- I just installed the active directory helper, this wassn't installed I think this might have been the problem. http://social.technet.microsoft.com/Forums/en-US/operationsmanagergeneral/thread/8d6936aa-1ea5-4156-8d46-1285d268e050/ About the limitations I think there aren't after reading the AD guide they fixed it.
