help with authentication problem between Windows servers

Hi, We need someone in the US, Canada, or the UK for this one as we're going to have to get on the phone to discuss this project. The ideal person for this job knows AD well and probably has an MCSE or other MS certifications. We want someone that we can use for future projects as well. This link describes the problem we have: [login to view URL] We are not developing software but we are running a software application on 3 servers. When someone logs into Server A, Server A communicates with Server B. At that moment, we are getting the error described in the link. We feel this is probably a simple project for a knowledgeable person in this area. Specifically, we need help with setting up the SPN as describe in the article. Knowledge of setting up SPNs is required.
