Problem with Configuring BTS 2004 Development edition

Hi everybody! I am beginner in BizTalk Server. And i habe a problem with configuring BTS.
Here is my installation steps:
– windows 2003 enterprise (+ IIS, ASP.NET, FrontPage Server Extensions)
– MS SQL 2000 Enterprise (Setup type – Typical, Services account – domain account, Authentification – mixed)
– MS SQL SP3a
– MS SQL Analysis Services + Analysis SP3a
– SQLXML 3.0 SP2
– MS Visual Studio.NET Professional
– Windows SharePoint Services + SP2 (uninstalled Front Page Web Server extensions before), then configured SharePoint Services according to the \”Installation Guide of BizTalk Server 2004\”
– OWC10.exe (Office Web Extensions)
– sql2000-kb810185-8.00.0878-enu.exe (patch for SQL 2000)
– MS Office InfoPath 2003

Then I installed BizTalk Server 2004 Development Edition (Complete installation)
And then I tried to configure BTS :

– Do you want to create or join a BizTalk Server group? -Create
– Will this SSO server hold the master secret key? – Yes
– Do you want to create a BizTalk Host Application? – Untrusted
– Do you want to create a BizTalk Isolated Host Application? – Untrusted
– NEXT

– Do you to create an Analysis database? – Yes
– Do you want to use Analysis Server for BAM aggregation? – Yes
– NEXT

– URL BAS SharePoint site – http://BTS2004/sites/BASSite

– all windows after this I left by default, till “Windows Service Configurations” window, here I entered \”BTSadmin\” (it is an administrator account)

– in “Windows SharePoint Services site Configuration” window I selected:
– Title – Business Activity Services Site
– email – my personal mail address

– after this steps configuration process started, but in the middle of configuration process \”Configuration succeded\” dialogbox with two buttons [Retry] and [Cancel] has appeared. When I press [Retry] this dialogbox appears again, but when I press [Cancel] all configuration process ralls back.

WHAT DID I WRONG ??? (insatallation is made according to \”Installation Guide\” and on a single computer)

P.S. Sorry for my english, english is not my native lannguage
