You may have left the security scoping code in the report when you pasted the other report?
Try clearing everything in the Parameterized Query box and pasting in this:
DECLARE @v1_TrusteeScope nvarchar(max)
SET @v1_TrusteeScope = N'%TrusteeScope%'
SELECT DISTINCT vc.Guid AS [_ItemGuid], vc.Name, IP.[IP Address], IP.[MAC Address],
IP.[Subnet Mask], IP.[Default Gateway], vc.[OS Name], vc.[OS Version], va.Status, va.Manufacturer, va.Model, va.[Serial Number]
FROM dbo.Inv_AeX_AC_TCPIP as ip
Left Outer JOIN
dbo.vComputer as vc ON IP._ResourceGuid = vc.Guid INNER JOIN
dbo.vAsset as va ON vc.Guid = va._ResourceGuid
WHERE
(
(ip._ResourceGuid IN (SELECT [ResourceGuid] FROM [ScopeMembership] WHERE [ScopeCollectionGuid] IN (SELECT [ScopeCollectionGuid] FROM dbo.fnGetTrusteeScopeCollections(@v1_TrusteeScope))))
)
ORDER BY vc.Name, IP.[IP Address]
