Hi,

Application environment (single server):

Windows 20003
AS2000 SP3
ADOMD.Net, XMLA
ASP.Net application with Windows Authentication, impersonation.

Everything was working fine, we are able to make connections, run MDX
queries, etc.

While running concurrent user tests, couple of users at the same time got
the following error:

Microsoft.AnalysisServices.AdomdClient.AdomdConnec tionException: A
connection cannot be made. Ensure that the server is running. --->
System.Net.Sockets.SocketException: No connection could be made because the
target machine actively refused it

We are about to go production and I need to figure out why this error is
occurring. Are there specific things I should be looking to tune with respect
to AS, XMLA?:
- number of threads,
- number of connections
- number of processes

Thanks for your help
Murthy.
