MSSQL slow on IIS 6

[php-taz]

I built a PHP website on Windows 2000 (using IIS) that connects to a
SQL Server 2000 database using the mssql functions. I migrated the
website and the database onto a Windows 2003 machine, and now the mssql
functions are significantly slower. On the Windows 2000 machine, the
mssql_connect takes .03 seconds to run, and the odbc_connect takes the
same amount of time. On Windows 2003, the mssql_connect takes a full
second to run, but odbc_connect only takes .017 seconds. I have tried
both ISAPI and CGI for the php configuration in IIS, and I have
experimented with different values for the output_buffering parameter
in php.ini, but neither of these seem to make a difference. Why would
the mssql commands be so much slower on IIS 6? I would rather not have
to change all the database calls to be odbc instead of mssql

How do you authenticate? SQL user/password or secured connection?

I think an mssql newsgroup might be a better place to ask this. I
suspect it's going to be in some parameters in mssql.

There shouldn't be any difference from the PHP end.

I am using a secured connection:

$sqlconnect=mssql_connect("10.4.61.156","","") or die ("unable to
connect");

Try it with SQL Server authentication instead and see what happens.

Same thing, it takes a full second to connect. Another difference
between the two servers is that SQL Server on the old machine is set up
to use just Windows Authentication, while this new server uses Mixed.
Would this effect connection speed?

Fixed. In IIS, the web site was not set to Integrated Windows
authentication. It was using the anonymous user account

[php-taz]

Actually this is not quite fixed. I need to use Integrated Windows
authentication, and that is what's slow. When I enabled Anonymous
Access with a username that is in the local Administrator's group,
connection was fast. When I remove anonymous access, and the user
accessing the web site is a local Administrator, it is still fast. Any
non-admin has a slow connection with Windows authentication. How can I
use just Windows authentication and have the connection be fast for
users who are not local Administrators?

Sounds like you need to follow up in a Windows related newsgroup. This
definitely isn't a PHP problem.
