j2ee -jdbc driver error

sir,
kindly solve the error.When I do a database updation in the
ejbcreate function the driver is working properly but when
I tried to use a user defined function I am thrown an the
exception listed below.This means that teh classpath
settings are fine .Probably the access writes are not
defined properly so I am posting you server.policy file
also just in case there is some problem.

java.sql.SQLException: [Microsoft][SQLServer 2000 Driver
for JDBC]Can't start a
cloned connection while in manual transaction mode.

Issues trying to connect to SQL Server

I am trying to connect to my SQL Server from my website and am trying to solve my issues with"...not a tursted SQL Server connection." but in the process I have created a new problem. Everytime I try to register a new server I get the error message:

'Connection Open (PreLogIn handshake())

Any ideas what I did to create this issue and how I can fix it?

Thanks!Check the default NETLIB is TCP/IP and listening ports are configured as per the protocol. BTW any firewall is involved here.|||I got it figured out but...

What concerns do I need to allow for since I do have a hardware firewall in place?|||Any firewall on the environment, access should be enabled to allow users. In fact we had an issue earlier with such behaviour and figured out the culprit is FW.
