Question : SQL Server instance just disappeared

I'm running SQL Express on my Win Server 2008 R2.  I hadn't touched the server in a few weeks, then needed to run some SQL queries.  When I try to connect to the Database Engine, as I normally do, it can't find the Server SQLEXPRESS.  I've been able to connect this way for months, and all of a sudden it can't find it.  

When I try to browse to the server, NO servers show up in the Local Servers list.  Yet my web page is still able to pull data.

Please help!  

Answer : SQL Server instance just disappeared

Have you tried a reboot of the SQl servers?
