Hi,
but when i install oracle express edition 10g on that machine i am able to connect to the remote database
Does the client machine have an Oracle Client installed before you do this at all? An Oracle Client is required in some fashion to use ODP.NET - either a full-client or the instant client if you are using a version that supports instant client.
