I am new to Citrix Metaframe. Recently I had a virus attack and My Citrix server crushed. I have re-installed all the necessary services and also installed Citrix Metaframe 4.0. I have published applications on a myfarm and I can open then in Citrix program neighborhood. The problem comes when I try to access the applications through the web. I am using IIS and Terminal services. When I type my server URL e.g http://localhost/citrix/metaframe/auth/login.aspx, I get the logon window but when I type a username and password, I get the ERROR, The supplied credentials could not be validated. Either they are incorrect, or there is a problem with the authentication system. Try again, or contact your help desk or system administrator for help. I want to authenticate users to a domain and I have configured the correct domain. How would I work around this problem? Thank you
