Description:
------------
When trying to connect to a local MSSQL 2005 Express server using mssql_connect() in combination with IIS 5.1 on Windows XP SP2, I get this error:

PHP has encountered an Access Violation at 7333F15A

When I run the script some more, I get this error.
PHP has encountered an Access Violation at 7333F179

When I run the script some more, I don't have a problem.

When I connect to another MSSQL server than my local one, I don't have a problem at all.

I tried it with PHP 5.2.5 and 5.2.6RC5

I'm not the only one with this problem:

When I use Apache 2.2.2, Apache crashes with PHP 5.2.5 when trying to connect.

BTW: I'm using the newer ntwdblib.dll (2000.80.194.0)


Reproduce code:
---------------
$username = "sa";
$password = "*********";
$database = "plrapport";

$conn = mssql_connect("LAPTOPHP\SQLEXPRESS","$username","$password");



Expected result:
----------------
Nothing should happen, but the connection should be made. I check if the connection is made by running a query.

Actual result:
--------------
When I just try to connect, with or without issueing a query, I get 
PHP has encountered an Access Violation at 7333F15A

I tried to make a backtrace, but I ended up with a very long mht file.
