We are considering migrating from a multi-network/single subnet workgroup to a domain environment utilizing Server 2008.
We have a resource that is hosted on Server 2003 and accessed via IIS by our workgroup clients at a remote location. This proprietary software operates with SQL server and it is confirmed with the vendor that the package will not operate correctly INSIDE a domain, thus the reason for the workgroup set up. They refused to give a reason why this is the case leaving us to guess.
Is there a method (perhaps through a trust relationship?) to allow domain client computers running Win7 Pro or WinXP Pro to access this resource without migrating the resource to the domain?
I am very new at network and server administration ( < 1yr) so please be gentle.
