Cookie Problem with IIS/PHP

I'm having a strange problem.

I have a php site with a login. The login works fine on the machine with IIS running and edits a mysql db like it should as well as setting the cookie.

However when i try and login from another machine the cookie doesn't set. It manages the login confirmation and the db edit but no cookie.

I can't figure out why it will work on the server but not on a remote browser. I've tried a few machines.

The odd thing is that i have the same php code on 2 other servers and they both work fine when remote browsers login. It's only this 3rd server thats not working (and as usual the one i need it on). I don't think it's php for this reason but instead something onthe server either permissions based or IIS thats stopping it giving out a cookie.

Unfortunatly it's way above my head what to do to solve it. I've uninstalled and removed IIS, SQL, php and reinstalled them with no success either. I was thinking maybe NTFS as the HDD security settings are very messy atm. But before i format and start over i thought i'd look around and see if theirs anything i've missed.

cookie request is just a simple one like the one below. Server is only running winxp pro too.

setcookie("uname", $name, time()+36000);

I don't use PHP with IIS. I don't know why cookies would have a problem.

ahh well

guess it's just one of those odd problems

I'll just start over. Thanks

You might look around on the php website, or ask in the php section of these forums. There are a lot of php/windows users here.
