Hi,
We are having 8510 Controllers and configured L3/web Authentication for Guest users. Our issue is that when we are enabling DNS recursion on windows dns server, clients is not able to browse internet. They are receiving the authentication page and after authentication its not redirecting to internet. NSlookup is working fine for this clients. After disabling this feature things started working. As a security feature Windows team need to enable this feature, so kindly let me know weather any setting needs to change on controller.
Thanks
Nibin
