3.5 Active Scan error: domain.com dc01.domain.com Index was out of range

[MattG]

Domain.com is throwing this error when trying to get 3.5 Active Scan to scan my network:

3/11/2009 10:32:02 AM: domain.com dc01.domain.com Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
at System.Collections.ArrayList.get_Item(Int32 index)
at System.DirectoryServices.ResultPropertyValueCollection.get_Item(Int32 index)
at LansweeperService.mdlActivescanning.ActiveScan()

I have a sub.domain.com that is scanning fine.

Could you try a "dcdiag /e /q" on a topdomaincontroller of your domain please.
