The thing which bothers me is that OP appears to have taken Shakespeare's solution (undoubtedly the correct one here) as a silver bullet, and edited his sqlnet.ora, without actually trying to understand what is going on (hint: it's going all over the Windoze network trying to find a database which is probably on the same box).

IMHO, this attitude is unfortunate; it won't aid him in thinking through his next problem.
