Yesterday everything was working perfectly.
Today, I came in and tried to load the Lansweeper Web Console, and I get the message "You are not authorized to view this page". 401.1.
Nothing that I can think of has changed. The database is still running in SQL Server 2005, the SQL and Lansweeper services are running, the Lansweeper Configuration utility works fine. Computers are still being scanned, and the results updated in the configuration utility. Just the web console is hosed.
I'm logged into the server as "Administrator", which is the same account everything was installed as.
I've tried connecting from another computer, I've tried restarting all the services, I've tried reinstalling just the web portion of the program.
What could possibly have gone wrong?
