Trying to connect sqlserver client wiht sql server desktop engine over internet. Here is the connection string

conString = "Provider=SQLOLEDB.1;Persist Security Info=True;Initial Catalog=" & dbName & ";Network Address=" & IPAddress & ";Data Source=" & DataSource & " ;User ID=" & UserId & " ; Password=" & Password

there is no firewall. Because i m trying in one room with two computers connected directly with the internet. I want this to be confirmed that any window operating system like win98 or win 2000 would do the work or there is any restriction.

i must also put here that the ping is not even working. this could be the main problem. i m not a master of network. so plz guide me out of this scene.
