I am using 5508 controllers, configured for WEB-AUTH passthrough, Windows XP clients work fine but Windows 7 clients are hit and miss getting redirected to the splash screen.
The login page is customised showing T's & C's with two buttons Except or Reject.
Do I need to Pre-Auth with ACL's? Has anyone had similar issues, or any good doc's etc.
Thanks in advance for any replies.

Can you check the web browser ? is it the same on XP an 7 ?
Just for testing, can you try Chrome or Firefox ?
It may be a browser issue rather than an OS issue

Well in order to get the Webauth page, the user's homepage can't be a secure page... Https. I have many installs with guest Webauth and no issues at all. The only thing is depending on your java script, sometimes an active x Erving appears in which they have to accept before the accept button works.

Nicolas,
Many thanks for your relpy, the problem is that this is a guest network that's also avalable to the public and I dont have any control over the end clients.
After doing a quick search on the net I found this.
NCSI : Uses a combination of DNS and/or HTTP look ups to tell if you are connected to the Internet. The way NCSI does this is either via a HTTP request for http://www.msftncsi.com/ncsi.txt or a DNS look up for dns.msftncsi.com that resovles to 131.107.255.255.
NCSI does this whether you are logged on or not.
Do I need to Create a Preauthentication ACL on the Guest WLAN interface:-
Configure a preauthentication ACL on the WLAN to allow wireless clients to allow:-
1. Permit DNS resolution (UDP/53) to 213.199.181.90
2. Permit TCP port 80 to 131.107.255.255
