When I try to create a new database connection, the Data Sources (ODBC) programs hangs or takes a very long time to find the list of available SQL Servers.

This only happens when there are other computers on the network, when my machine (a standard Windows 7 laptop) is alone, it works just fine.

ODBC Window - hangs when I try to select SQL Server

My question is: What should I look for in terms of SQL server or ODBC configurations that will take away this random behaviour?

It's not direct answer to your question, but in Server field you can write in ServerAddress or ServerAddress\InstanceName:

write address

So when you know this value don't do server discovery (expand the list). List all Sql Servers in (large) network usually takes long time.
