Reporting Services - Web Service Credentials

Dim objRptServ As New ReportingService
'Assign default credentials for web service access
objRptServ.Credentials = System.Net.CredentialCache.DefaultCredentials
Guys, I was hoping someone might be able to shed some light on this subject.
The above lines of code made available via an asp.net web form locked down
using windows auth and inpersonate=true set in web.config does not pass
domain user creds to report server.
I'm assuming problem relates to IIS 6.0 security model and application pool
security identity. Here is my therory.
Page works as expected on a WindowsXP development machine running IIS v5.1
and ASP.NET worker process security. When page is copied to IIS v6.0 web
server page no longer works? the only thing that has changed is the version
of IIS ? Your thoughts please? and any suggestions as to how this may be
overcome would be appreciated.
Thanks in advance for your assistance.
-BenHi Ben,
From your descriptions, I understood that it works fine with IIS 5 while
you encounter credentials issue. If I have misunderstood your concern,
please feel free to point it out.
First of all, please reconfirm the configuration of IIS 6 is the same as
IIS 5. It seems you should be using IIS 6 with Windows Server 2003? If so,
please make sure nothing was blocked.
Secondly, please package your Reporting Services log files in a zipped file
send to v-mingqc@.online.microsoft.com (please note that 'online' is only
for SPAM)
Thank you for your patience and cooperation. If you have any questions or
concerns, don't hesitate to let me know. We are always here to be of
assistance!
Sincerely yours,
Michael Cheng
