Communication between SQL6.5 and SQL200

Hi!
I'm in a fix, we're changing domains and I need to communicate between SQL6.5 and SQL200 for a short while.
Both servers reside in the same domain (at the moment) so all I want to do is communicate between 6.5 and 2000.
There seems to be a problem with that...
Is this a common problem?
WCS is to install 2000 on all machines, but time is agains me. I will get to that evenually.

Any ideas?

The communication I want is to access data in a table in SQL2000 using a SP on the sql2000 server. The call is invoced by a SP on SQL6.5.

Anu ideas?

Thanks!

And as I can see it, there was no problem...
It worked just as it's supposed to do, but I had other errors to handle first.
