IIS and SQL Server on separate machines

[stephen]

Hi,

I am facing this problem:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL
Server connection
IIS and SQL Server on separate machines using NT security and I am able to
access the page...
I asked another developer to access the page and he was not able to get to
the page...

I checked the SQL Server logins and both the developer and me were users of
the database...
both of us are in the same domain
I tried <identity impersonate="true" /> and still no result....

I read this article
http://support.microsoft.com/kb/q176379/
Is this the way to go?

I want to user Windows NT authentication method...

Thanks,
Stephen
