Just to update this. I have found a way to remotely connect via SQL. However, this is not the answer to the question. It appears to be a limitation of querying the Index Server remotely. I can workaround with a remote COM+ object, but I am hoping for an answer without having to resort to this. Can anyone provide me with any limitations of querying the Index Server remotely (I know this is a bit off topic, but there doesn't appear to be any forums on the Index Server on wrox)?
