Reporting Services is loosing stores credentials during connecting to Analysis Services

Hi, experts.
I have another strange problem with Reporting Services.
There are two machines:
-machine A with ReportingServices +IIS but without SQL SERVER nor
Analysis Services
-machine B with SQL Server and Reporting Services.
There is a web application in the machine A that collects data that
the web user
sends to the web server in order to pass it as parameters to Reporting
Services using a POST method. This POST method is sent from the
browsers (the web server
generates a form with hidden fields that are automatically sent to
Reporting Services by means of JavaScript).
Stored credentials are used in the datasource configuration and I've
put
all Services Packs that are available.
When the user wants to see the report for the first time, everything
works smoothly. Once it returns to the main page in order to visualize
other report or the same report once again, it is not possible to
connect to Reporting Services due to the security issues (dimension
not found error is obtained).
If I close the web browser and open it again, I can seee one report
and then
I obtain the same error.
I think that stored credentials are lost, but I have no idea how I can
fix it.
Thank you in advance for any ideas
Maciej Kiewrahmm...Are both your RS servers set up for Win Auth?
Depending on how your domain is configured, Windows credentials can be
passed across one computer connection before they expire. A user connection
to a report server counts as the first connection. If the user opens a
report that retrieves data from a remote server, that login counts as a
second connection and will fail if you are using Windows Authentication and
Kerberos is not enabled.

I´ve solved it. The problem was related with the user that
executed the web application ReportServer (IWAM anonymous access).
I´ve put a user that has access to Analysis Services in the anonymous
access option and now
everything works fine.
