Excuse me if this is too open-ended but,
I have a Windows Server 2008 R2 Standard. It's running a SQL Server 2008 database server. (all 64bit if that matters). Earlier today they had a power outage. After the power came back on no clients could connect to the database from any machine other than the server itself.
I made sure Shared Memory, TCP/IP, and Named Pipes were all still enabled (which they were) and the SQL Server (MSSQLSERVER) and SQL Server Browser services are running.
I have a web server on the same network running a php app that only since the power outage can no longer connect.
I can still ping the database server and I can connect to the database locally. Any idea what the problem could be?
