Databse Link will not connect

P: n/a

I have a couple new servers - Windows 2003 R2 - with SQL Server 2000
SP4 installed. They are all Active/Active clustered instances (my
first ones).

I am trying to create database links to other SQL Server instances, but
there are 3 that I cannot connect to.

The dblink works if I connect to the instance as "sa", but not as my
Windows Authenticated account. We use Active Directory and I am in the
Administrator group on all of the boxes.

Of the 3 I can't get to, 1 is a cluster (Active/Passive) and the other
2 are just regular Enterprise instances. They are all SQL 2000 SP4.

I have several other instances, all SP4 on 2003 boxes and I can connect
to all of them.

Also, on the instances where the dblink does not work, I can actually
connect to these databases w/in Enterprise Manager successfully.

I am using a different port for the instances, but I have set them up
in the Client Network Utility as well and still can't connect.

I can connect via a dblink TO these new instances from the older boxes
fine.

I'm really stumped - I've had the Network people verify we don't have a
firewall issue or something.

Must be some sort of permissions problem, but I don't know what else to
check - - -

Please help!!

THANK YOU!!

Not completely sure what you mean by a dblink, but what SQL permissions
do the Administrators have on each server? Are you sure the
BUILTIN/Administrators Windows group have the appropriate permissions
on the databases you want to select from?

Thank you!

By dblink I am referring to a linked server. (I apologize - I come
from an Oracle background).

The BUILTIN/Administrators group has all of the System Roles and it
still did not work.
Other boxes have links into the server/instance which work fine, and
the new server can link to other servers.
It's strange because it's just this one combination that does not work.
Group A: oldest servers; non-clustered; Win 2003 SP1

Group B: medium servers; 1 a/p cluster; 2 non-clustered; Win 2003 SP1

Group C: newest servers; 3 a/a clusters; Win 2003 R2

All SQL Server 2000 SP4

Group A can link to Group B
Group A can link to Group C
Group B can link to Group A
Group B can link to Group C
Group C can link to Group A
Group C CANNOT link to Group A if logged in using Windows
Authentication

All of the links are set up using "sa".

You may want to google "double-hop" and SQL Server; I'm not sure that I
understand your scenario, but a few articles might ring true.

Thanks -

we're not double-hopping.

If you go to Enterprise Manager, under Security there is "Linked
Servers".

If I am on one of the boxes in Group C, I am unable to open the link to
any of the instances in Group B if I am logged into the instance using
Windows Authentication. (Sorry I had a typo in the last message).

I've recently discovered that if I change the port back to 1433, the
database link will work. However, I am uncomfortable going back to the
default port.
All of my other links work fine.

Also, the servers in Group C are using 64-bit Windows (but 32-bit SQL).

thanks,
tc
