Child Domains + SD / OpManager Integration

Hi There

We have just started using OpManager and have been looking at using SD+ for software and hardware asset/inventory.

We are in the UK and are a child domain of our US head office.

I am having a few problems though.

1) When performing a domain scan - it also scan's the parent domain too, causing alarms in the US and a lot of errors in SD+ as the domain user does not have rights over the parent domain.
Is it possible to have it scan only the child domain?
Also, it doesn't list the domain controllers in the assets, but works when I do a manual scan.

2) In OpManager, it has discovered some servers as as their dns alias's instead of their NetBios names, so when you click on the Service Desk Asset button in OpManager, it can't find the server, even if you edit the server name.

I would be grateful of any help.

Cheers

Tim
