Can alias in SQL Server contain slash?
You can create a client alias on the application server. You will have to run CLICONFG.EXE on the client, click add on the alias tab, click TCP/IP add the server alias B and set the connection paramters to be FC\SQLSRV after this all connections to server B from that client/application server will be forwarded to FC\SQLSRV If your application is 32bit you will also have to do the same for the 32bit registry and run %systemroot%\syswow64\cliconfg.exe
