Dear All, Today i resolved an issue which is very basis but the solution is little bit tricky. The problem was related to accessing the website on LAN through IP or the domain name by anonymous user. I setup the site through IIS and run it on local host, the website runs perfectly. But when I tried to access the same website through IP Address or Domain Name it's prompting the user name and password. I do the following steps but i did not get any success 1) Open the site property in IIS through website property and allow anonymous access Result the website still ask me user name and password 2) Open the web.config and add the following code <authorization> <allow users="*"/> //Allow everyone </authorization> Result the website still ask me user name and password 3) I made the the directory permission on every one and IIS user Result the website still ask me user name and password 4) I change the IIS_USER to Administ
