Working with IIS 4 and ISAPI, and having added the following lines to php.ini

*snip*
mssql.textsize  = 8192 ;
mssql.textlimit = 8192 ;
*snip*

a request of a field with Data-Type Text  > 4kB gives back only the first 4kB of the text (in general).

The interesting phenomenon is:

After restarting IIS completely (net stop iisadmin), the WHOLE text  out of the DB (appr. 6kB) will be returned, but only ONCE (meaning a reload in the browser, taking another browser, etc. gives again only the "cutted" text-field). 

Working in CGI-mode, the whole text will be returned every time.

A exemplary code-snippet, if it helps:

**shortened snip**
  $check = "SELECT * FROM $table WHERE $QUERY_STRING";
  $result = mssql_query($check) or die("Konnte die Datenbankabfrage nicht durchf?hren.");
  $row=mssql_fetch_row($result); 
  $head  = makehtmlchar($row[2]);
  $body  = makehtmlchar($row[3]);

  $mytext .= "
    <table width=610>
    <tr><td><h4><b>$head</b><br><font class=stdtext>($row[1])</font></h4></td></tr>
    <tr><td><font class=bigtext>$body  </font></td>\n";
