Can't Connect SQL Server

I Have Three Server , Only One Can't Connect SQL Serve , Another Can Connect
SQL Server
I don't Know What Happen
Who Can Tell Me what can I do?
Hi,
This error will come due to below reasons:-
1. Network issue - Not able to connect from client to SQL server machine
2. SQL server Service might be down
3. Connecting to wrong machine
Can you try creating a Alias of the SQL server in you client using "CLient
Network utility". USe the TCP/IP protocol , IP and port number of server.
After that use this Alias name to register in enterprise manager.
See the below link.
