Strange Timeout

Hi! I usually work with Apache webserver but now Im working with a php project that uses ms sql server 2000 This webserver is running IIS6 and I get som strange errors. As i said earlier i get a strange CGI error when I use the header("Location: ".$_SERVER["PHP_SELF"]."?page=something"); I just upgraded to php 4.3.8 and that problem seems to have been solved. But now I have encountered another strange one. On some of my pages i insert alot of data into the sql server, and if that is successful I send the user to another page. But this times out... all the data goes into the database without any problems, but as soon as the script reaches the header(); it dies... and after a while i get a execution timeout error. I know that its not the sql queries who kills the server, becouse if i Replace the header with i.e print("IT ALL WENT WELL! "); it prints and all data gets stored. Have anyone else encountered this problem? or do anyone have a clue about what to do ? .odde --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
