Problems then installing datawarehouse

Hi Im installing a Commerceportal site with the following configuration. CP server Windows 2003 Navision 3.70 Commerceserver 2002 SP3 SQL server Windows 2003 SQL 2000 SP3 I get a error message the im unpackiong the Datawarehouse that say: “Invalid connection information for OLAP service” Before I installed the new servers I installed everything in a test enviroment there both the commerceserver and sql server was on the same machine and it worked fine. Anyone got a clue what i missed? I have no problem testing the database connection to the DW database during the part of the “pup” where I select databases.
