Hi Everyone,
I faced this same issue today and was able to resolve following two basic steps:
1) Checked CMC for FQDN, followed by check on the hosts file found in path "C:\Windows\System32\drivers\etc". I had removed the ID and used the correct name there. Also please ensure concurrence between the entries in host file and CMC -> Applications -> Web Service Name.
Do ensure all the relevant services are ON.
2) I checked the privacy and content policies on the Internet Options of Internet Explorer [Main Browser used for portal activities], I had reset them to a lower security level than current with pop-ups allowed from this portal and other content and trust level activities. After adjusting them I was able to successfully re-login and goto my dashboards.
Regards,
Abhishek Sharma
