Cookies PHP 5.2.6 IIS5/2000

I think there may be a cookie issue under my configuration - PHP 5.2.6 on IIS5/2000. I have to manually manipulate my cookie to login/logout of piwik (under multiple browsers) and unique visitors are generating several cookies for one visit- one unique visitor will show up as multiple unique visitors.

Bump.
Is there somewhere else I should post this?

I didn’t seen this problem with IIS7. Most likely a php configuration issue.

“a php configuraion issue” is pretty vague. Have any specifics? Any debugging tips?

Also, I’m not using IIS7, I’m using IIS5. I compared the php configuration to a functioning ubuntu box, and they were identical as far as cookies/sessions go.

Well, the symptoms you describe aren’t something I’ve seen before, and it doesn’t give me many clues as to the cause.

Can you upgrade php? or try the forums on php.iis.net ?
