Can you access the basic SRS reports at
http://<servername>/Reports? If
not, you have an SRS issue, not a CRM double hop authentication issue, and
you will need to troubleshoot your SRS install.
A good document to get is the RSSetupTfD.doc from Microsoft. It goes over
additional steps needed for accessing SQL Reports. You can access it at
http://www.microsoft.com/downloads/details.aspx?FamilyID=51bf9f20-bd00-4759-8378-b38eefda7b99&DisplayLang=en Sometimes just adding the following entries to the ServicePrincipleName for
that machine under ADSIEDIT helps as well...
HOST/<servername>
HOST/<servername>.<domain>
HTTP/<servername>
HTTP/<servername>.<domain>
However, please make sure they do not exist already. The RSSetupTfD.doc
describes how to query for these in AD.
