sql connectivity issue

We have developed an app in vb6 and are having problems with connecting to sql server. OUR REQUIREMENT IS VERY SIMPLE. all we need to do is be able to connect to a remote sql server either by using sql manager or any 3rd party software. We have tried the ports configuration on the router etc... but no luck. We need someone who knows sql server and networking inside out and can help us with it. The os is winxp and 2003 server. we will give the address of a server in our company for the coders to test it. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
