SQL Server access denied

[ksbrace]

Hello,
I have 2 people working on a project that accesses SQL Server DB. One of the people have the DB on their pc. The other cannot get to the DB. They keep getting "SQL Server doesn't exist or access denied" on the connection.open() line.
Here's what my connection string looks like:

<add key="ConnectionString" value="server=10.0.0.2;database=IBS;uid=username;pwd=password" />

Both users are on the "10" network. The uid and pwd work just fine on the pc that holds the DB. Any help or ideas would be greatly appreciated. Thanks in advance!

Does the computer where the SQL DB is installed has an Firewall? Maybe the 1433 port (default SQL TCP port) is blocked for incoming connections.
