"Please test the connection with mssql client tools first." This was the first
initial test and authentication through Enterprise Manager or QA is fine.
"Connecting to mssql servers requires that the ports uses is open in the
firewall" There are no FW in use as this is a purely an internal connection.
"that the correct user id and password is used" User and password have already
been confirmed as correct.
"If
Integrated NT authentication is used you must specify
mssql.secure_connection = On in your php.ini file." The sql servers use Mixed
mode authentication with the connection string requiring the sql login user and
password, which are correct.
This was clear from the fact that web server A could not connect to sql server
B, however, using the same script a connection is possible from web server b to
sql server b. If the username or password was incorrect, no connection would
be possible, from anywhere.
Basically is there a problem when trying to connect to an SQL server with
mssql_connect when the web server is in a different non trusted domain to the
sql server?

Please test the connection with mssql client tools first.
Connecting to mssql servers requires that the ports uses is open in the
firewall, that the correct user id and password is used (if the SQL server
allows SQL server authentication) or that the user account used to execute the
PHP script is authneticated on the web server. If Integrated NT authentication
is used you must specify mssql.secure_connection = On in your php.ini file.

Description:
------------
Webserver A is in an active directory VHOSTS, webserver B is in Active
directory VHOSTS2. MSSQL Server A is in VHOSTS and MSSQL Server B is in
VHOSTS2. If an attempt is made to connect to MSSQL Server A from Webserver B
using mssql_connect the connection fails. However, if an attempt is made to
connect to MSSQL Server B from Webserver B using mssql_connect, the connection
will succeed. This also applies if you change the test around so webserver A
connecting to MSSQL Server B. This is purely an internal connection with the
only difference in the webservers and ms sql servers is being they're in
different domains.
Reproduce code:
---------------
<?php
db_connect();
?>
<?php
function db_connect ()
{
$db = mssql_connect ("sql2k230", "*****", "******");
if (!$db) {
echo "\nError connecting to SQL Server, User = '" . "" . "', p/w = '" . ""
. "' \n\n";
die('Could not connect to server: ' . mssql_get_last_message());
}
$result = mssql_select_db ('master', $db);
if (!$result) {
die('Could not select database: ' . mssql_get_last_message());
}
}
?>
Expected result:
----------------
The script above should have html included, in which case whatever html is
included should be produced in the browser after the db connect has taken
place. Or a blank page if using the code only.
Actual result:
--------------
Warning: mssql_connect(): Unable to connect to server: sql2k227 in e:\********
on line 28
Error connecting to SQL Server, User = '*****', p/w = '****' Could not connect
to server:
