Hi All, While confeguring SSO i am getting RPC error and log say User MYDOMAINNAME\USERNAMEUSEDBYSSOSERVICE failed to configure the single sign-on server. The error returned was 0x80070995. Verify this account has sufficient permissions and try again. The account has proper rights over the sql server and WFE server. Properly added to all the groups. We are using trial enterprice version of MOSS 2007. What could be the problem? manoj.verma
