An internal server error could occur for numerous reasons like - incorrect database server, incorrect username / password etc etc. The best way to approach this would be to find out what's the actual error. You have said that you could see the 1st page, but the error happens after you enter the user name/ password. What type of authentication does your web application / site use ? See if it's setup correctly in IIS under the "Authentication" module. Also, go to the server and visit your page there, instead of from a machine that just acts as a client. If you use the server itself, it will give you much more information than a useless "500 internal server" error. If you could do that and see the actual error, it might be helpful If you have qns. post it here and one of us will help! Its difficult to help w/ just the general 500 error...

Sometimes you have to load your project on the web server, and debug it from there. Some things that work on Server 2003 don't work on Server 2008.

So you can take a stab in the dark, and pick out just the login page code to debug on the server.

You may have to setup a temp server at your shop, to test and debug on, before you deploy to a production server.

I ran into that the first time I deployed on Server 2008, mostly things like

Request.Server("some context") failed.
Get IP Address instead of GetUserHostAddress
Folder Security issues, incorrect permissions for writing to the disk drive

If there is a long pause, then the Server Unavailable error, probably folder permission.

Thanks for your reply. Actually i didn't publish that site. i made two pages site without DB using MVC3 framework. I run on 2008 server but it was showing error. when i assigned the port number and publish it again now it runs.

Oh, so you had a problem with IIS7.5 Server, and did not make a bind on port 80 for that website. I think that should of resulted in a page not found error.

Well whatever. I read your words, you contacted the server, and the server replied with an error, so the port number must of been correct.

Good Luck.
