Reporting Services not working after Windows 2003 Service Pack 1 installed

Help. After we installed Windows 2003 service pack one the SQL reporting is
getting an error:
The request failed with HTTP status 401: Unauthorized.
Can anybody help?Check if the 401 error has the same call stack as discussed in this thread:

Reporting services fail to return large report

I have a huge report (approx. 120MB) needs to be returned from reporting
services. However, most of the time the request die before the report is
returned.
While I am debugging this problem, I realize that an exception is thrown
between the BeginRender() and EndRender() methods of Reporting Service.
Exception:
Unable to read data from the transport connection.
I am not sure if there is any limit in report size that can be
generated/transported from reporting service. Reporting service is called
from another ASP.Net web service. This web service also resides in the same
box as reporting service and SQL server 2000. This box is running Win 2003
and IIS 6(IIS 5 isolation mode).
Here is the code snippet:
----
ReportingService oRS = CreateReportService(sRSession);
IAsyncResult pWait = oRS.BeginRender(m_sReport, sFormatName, null,
sFormatInfo, aParams, null, null, null, null);
if (pWait.AsyncWaitHandle.WaitOne(new TimeSpan(ReportGenTimeout(), 0, 0),
false))
{
byte [] abResult = oRS.EndRender(pWait, out sEncoding, out sMime, out
aUsedParams, out aWarnings, out asStreams);
}
else
{
oRS.Abort();
throw new ApplicationException("Report Generation Timeout Expired");
}
Any help will be greatly appreciated. Thanks.
JocelynHave you tried the report from Report Manager to determine if it is an
integration issue or running a report issue?
What format are you rendering it? If it is not html then instead of report
manager test it using URL so you can specify the render type.
My guess is that it is too big. RS is not designed for this sort of thing. A
lot of rendering goes on in memory so something this large could be
problematic which I why I suggested the above tests.

> Jocelyn|||A little over 100MB report was able to be generated and viewed from report
manager. The report is in html format.
All the smaller reports are able to be generated with the same codes. I am
not sure what kind of intergration issue may cause the huge report failed.|||That does tell you something (that it works from Report Manager). It could
be a timing out issue with IIS. Could be something different when using web
services that isn't there when using it from Report Manager.
