In DS 7.1 one of the challenges is that SMA clients do not always register to a local Task Server unlike Package Services, and because DS tasks are coded to look to the Task Server to which the client connected, DS task such as images can go across WAN.
Below is a sql query that can be used for mapping a client to connect local Site Server...
SELECT TOP 1 ds.[Task Server]
FROM [dbo].[vComputer]
JOIN [dbo].[Inv_AeX_AC_TCPIP] ON [dbo].[vcomputer].[Guid] = [dbo].[Inv_AeX_AC_TCPIP].[_ResourceGuid]
AND [dbo].[Inv_AeX_AC_TCPIP].[IP Address] = [dbo].[vcomputer].[IP Address]
JOIN [dbo].[vSubnet] ON [dbo].[vSubnet].[Subnet] = [dbo].[Inv_AeX_AC_TCPIP].[Subnet] and [dbo].[vSubnet].[Subnet Mask] = [dbo].[Inv_AeX_AC_TCPIP].[Subnet Mask]
JOIN [dbo].[vSiteSubnetMap] ON [dbo].[vSiteSubnetMap].[SubnetGuid] = [dbo].[vSubnet].[Guid]
JOIN [dbo].[vSite] on [dbo].[vSite].[Guid] = [dbo].[vSiteSubnetMap].[_ResourceGuid]
JOIN (
SELECT
[vSite].[Name] as Site
,[vComputer].[Name] as [Task Server]
FROM [dbo].[vComputer]
JOIN [dbo].[Inv_AeX_AC_Client_Agent] on [dbo].[Inv_AeX_AC_Client_Agent].[_ResourceGuid] = [dbo].[vcomputer].[Guid]
AND [dbo].[Inv_AeX_AC_Client_Agent].[Agent Name] = 'Deployment Task Server Handlers'
JOIN [dbo].[Inv_AeX_AC_TCPIP] ON [dbo].[vcomputer].[Guid] = [dbo].[Inv_AeX_AC_TCPIP].[_ResourceGuid]
AND [dbo].[Inv_AeX_AC_TCPIP].[IP Address] = [dbo].[vcomputer].[IP Address]
JOIN [dbo].[vSubnet] ON [dbo].[vSubnet].[Subnet] = [dbo].[Inv_AeX_AC_TCPIP].[Subnet] and [dbo].[vSubnet].[Subnet Mask] = [dbo].[Inv_AeX_AC_TCPIP].[Subnet Mask]
JOIN [dbo].[vSiteSubnetMap] ON [dbo].[vSiteSubnetMap].[SubnetGuid] = [dbo].[vSubnet].[Guid]
JOIN [dbo].[vSite] on [dbo].[vSite].[Guid] = [dbo].[vSiteSubnetMap].[_ResourceGuid]
) ds on ds.Site = [vSite].Name
WHERE [dbo].[vComputer].[Guid] = '%COMPUTERID%'
