Here's the situation: My production environment has two SQL Servers 2000,
call them S1 and S2. S1 also hosts IIS and my ASP.NET application.
On S1, I have created a linked server for S2. Thus, on S1, I can write:
SELECT * FROM S2.myDB.dbo.myTable
and everything is happy.
My development environment is slightly different. I have a single machine
running a single instance of SQL Server 2000 (acually, MSDE). I have made
local copies of the tables from both S1 and S2 in my local database. In
order to be able to copy, without modification, the stored procedures I
write on my development machine, I need to be able to access the tables in
my database as either:
myDB.dbo.myTable
OR
S2.myDB.dbo.myTable
To this end, I created a linked database on my development machine, but
instead of selecting type SQL Server (which forces the linked server name
and the hostname to be the same), I selected Microsoft OLE DB provider for
SQL Server (which allows specifying different hostname and data source
names). I specified my hostname as the data source and named the linked
server S2. SQL server dutifully made the linked server. Note that I have
confirmed the creation of the linked server by running sp_helpserver, which
does show both the local server (identified by the machine name) and the
linked server (identified by the assigned name) [but see more info below].
Despite this seeming success, I have been unable to do anything with this
linked server. Under the security tab, I selected 'Be made using this
security context', and entered 'sa' and its password. I then ran the query:
SELECT * FROM S2.someDB.dbo.myTable
and received: SQL Server does not exist or access denied.
Some additional information:
1- On the development machine, sqlservr runs under the SYSTEM context
2- Looking in the table master.dbo.sysservers, I saw the following
srvname datasource srvnetname
S1 S1 S1
S2 S2 S2
when running the query, it takes a while to respond, thus I am thinking that
it is searching the net for a server named S2 instead of using itself as the
datasource. If this is so, what can I do differently to resolve this
problem?

gerry@.pairofdocs.netYou could try adding a host entry for the linked server
with the same ip address as the development server using a
different name.
i.e.
192.168.1.1 development
192.168.1.1 Dev_Link
This will allow you to add the linked server as another
sql server.

Isn't a second instance for the dev box the most logical, desirable
solution?

I suspect that the problem is due to a bug in the documentation and a bug in
Enterprise Manager. Reviewing the document shows that the string 'SQL
Server' can be used as the product_name along with SQLOLEDB as the
provider_name. Trying this with sp_addlinkedserver yields the error message:
You cannot specify a provider or any properties for product 'SQL Server'.
but doing the same from Enterprise Manager results in success, even though
the entry in master.dbo.sysservers is incorrect.
