Description:
------------
After you run mssql_query("sp_help") all following queries fail. I am using PHP4.3.4 running as ISAPI module in IIS5 on Windows XP. SQL Server 2000, version 8.00.760.

When you uncomment both lines in the reproduce script:
while (mssql_next_result($result));
mssql_free_result($result);

the script does work.


Reproduce code:
---------------
if ( ! $connect_id = mssql_connect( $sql_host,$sql_user,$sql_pass ) )
{
	die("Could not create a MSSQL connection, please check the SQL values entered");
}
	
if ( ! mssql_select_db($sql_database, $connect_id) )
{
	die("MSSQL could not locate a database called '{$VARS['sql_database']}' please check the value entered for this");
}

$result = mssql_query("SELECT @@VERSION");
$row = mssql_fetch_row($result);
echo $row[0]."<br />";

$result = mssql_query("sp_help", $connect_id);
while ($table = mssql_fetch_array($result))
{
	if (($table[2]=="user table") && (!($table[0]=="dtproperties"))) {
		echo $table[2]." | ".$table[0]."<br />";
	}
}
// while (mssql_next_result($result));
// mssql_free_result($result);

$result = mssql_query("SELECT @@VERSION");
$row = mssql_fetch_row($result);
echo $row[0]."<br />";
mssql_close($connect_id);	
?>

Expected result:
