Sorry for the vagueness of my post. The SQL Server is located outside our LAN. Our SQL server is being hosted in the internet (Innerhost.com). What we are doing is connecting to that server on the internet using Enterprise Manager to transfer databases/tables. And our problem is that it seems that the ISA is blocking 1433 port thats why we are encountering the DBNETLIB error. I configured our ISA for outbound/inbound access for port 1433 but still in no luck. Please advise us on necessary steps..Thanks in advance!
