According to this syntax:

Class.forName
("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
Connection c = DriverManager.getConnection
("jdbc:microsoft:sqlserver://DEV-
ACC:1433;DatabaseName=dev",user,password);

what should I put instead of DEV-ACC if my server name \\HOME\EHSAN

for example the below code has got problems and is not working

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection c = DriverManager.getConnection
("jdbc:microsoft:sqlserver://HOME/EHSAN:1433;DatabaseName=roshd","ehs
an","ehsan");
