XMLA .NET connection problems

[Juan]

Hi, After install msxml 4.0 and XMLASDK 1.1, i proceed to configure the datasource.xml file, as follow:
<DataSource>
<DataSourceName>FoodMart 2000</DataSourceName>
<DataSourceDescription>Microsoft Analysis Server 2000 on local machine</DataSourceDescription>
<URL>http://localhost/xmla/msxisapi.dll</URL>
<DataSourceInfo>Provider=MSOLAP.2;Data Source=md001144</DataSourceInfo>
<ProviderName>Microsoft XML for Analysis</ProviderName>
<ProviderType>
<TDP/>
<MDP/>
<DMP/>
</ProviderType>
<AuthenticationMode>Unauthenticated</AuthenticationMode>
</DataSource>

Then i created a Virtual Directory as mentioned in the sdk help
but when i try to connect using the Sample.Net included in the sdk,
the application shows a Message Box: "No Catalog Found at this session"

In the Analysis Server i have two servers running:
mdsqlserver
and
md001144 (local) in which i have the FoorMart 2000 Sample (the one i want to access)
Do You Have Any Suggestions??? Thanks!
