Connection reset by peer error when using pubdbexecSQL

I am trying to connect to a SQL Server database using the execSQL service in the developer and I keep getting the same error:

Error in JdbcConnectionTester.main()
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Connection reset by peer: JVM_recv in socket input stream read

Has anyone seen this before? How did you get around it?

I am pretty sure that my connection information is correct and the database is up and running.
