We have two sql servers using Windows authentication. One is sql 2000 the
other sql 2005. When logged in as "sa", I can link these servers and run a
SELECT distributed query without any problem.

But when one of our developers runs the same query (he is "dbo" of each
database on each of the servers) he gets the error:

"OLE DB Provider "SQLNCLI" for linked server <Servername> returned message
"Communication Link Failure"
...
Login failed for user '(null'). reason: Not associated with a trusted SQL
Server connection"

Despite that,  I, as "sa" equivalent,  have no problem so it appears to be a
permisisons issue. Any ideas what is going on here?

TIA,

Bill
