Windows 7 and LDAP

[jharmor]

The majority of our uses have Win XP as their OS and they can log into Cognos 10 using single sign on and their credentials verify without problems and they can use Cognos. A few users have been getting Win 7 as their OS. For them when they reach the portal a login box appears asking them to enter their user ID and Password. The user enters the information; however, the credentials won't  verify and they are denied access to the Cognos portal. Where should I start looking IE security permissions, Win 7 Security/network settings?
Thanks.

Try Windows Firewall - it got more complicated with Win7.    Also, make sure the site is in Local Intranet zone of IE

Thanks, I give that a try.
