Dear friends,

We have a iis 6.0 in a w200 member server in our domain, we also have
sql2005 in the same computer. We deployed a BI solution (integration,
analysys and reporting services), reporting services uses IIS as a frontend.
The problem is the next , i have integrated authentication selected in the
default site (is the site used to acces the reports folder), when clients
access the site via netbios name they don't get prompted for authentication,
and work in the reports they have permissions. When users user the fqdn of
the machine they get prompted for credentials, they use their domain account
and use the resources they have access to.

I checked the setspn for the principal name registered in kerberos and all
seen ok

Registered ServicePrincipalNames for
CN=COMPUTER,CN=Computers,DC=DOMAIN,DC=ORG:
    HTTP/computer.domain.org
    HOST/computer
    HOST/computer.domain.org

i can't understand why if i use computer/reports it user integrated
authentication and when i use computer.domain.org/reports it prompts.

A kerberos issue??

It's an IE security feature - you would need to get your users to put
http://computer.domain.org into their Trusted Sites zone for IE to
automatically use integrated auth without prompting. If the FQDN contains a
.. then it will prompt, if it doesn't then it won't.

Dan,

No way,  i tried to put in trusted sites the fqdn of the computer and it
continues to prompt for authentication (if i put the right credentials i can
acces). i also changed the app pool user to localsystem (more security
privileges). I used also authdiag and all seem correct. If i use ip or the
netbios name all goes well.

Any help?

Hi Jason,

Trust site zone shouldn't work. You have to add the site to Local Intranet
zone. IE will perform automatically integrated windows authentication with
IIS only in case the site is in local intranet zone, or if you access it
with http://servername which is considered a local site.

All the details can be found in below article:

Internet Explorer May Prompt You for a Password
http://support.microsoft.com/?id=258063

Let me know if there is any further issue.

Have a nice day.

Sincerely,

WenJun Zhang

Oops, I should have written Intranet Zone. I see WenJun gave you the correct
answer. Unfortunately I had no newsgroup access last week so couldn't post a
reply earlier.
