Question

Server Error in '/' Application, Login failed for user 'Doamin\user$'

2956 1

I am migrating a web application from one server to another new server. Everything is fine until I publish the project on the new server. After I logon I get a server error in '/' Application. The error message is:
Server Error in '/' Application. Login failed for user 'Domain\user$'. An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I could logon if I run my ASP project "start without debugging". Any clue to fix it? Thanks.

Hi @2956 ,

How you migrate the application? You need to figure out what the Domain\user$ used for. If it is used to login SQL Server, you need to check if it can login SQL Server directly in MS Server management. If it just a custom user, you need to check if it still exists in web.config. Web.config should has an item like this: <identity impersonate="true" userName="domain\username" password="********"/>.

So you'd better check event viewer for more detailed stack trace message.

On the old server check which account is used for the app pool and match on the new server. Also check the account used for anonymous access.
