Who are you impersonating?

Been going through the pains of installing VS Team Foundation Server.
Here are a couple of pointers for others who may be suffering through the same process.
Make sure that Sharepoint, Reporting Services and TFS are all using the same account. That is, LOCAL SERVICE or NETWORK SERVICE but not a combination of BOTH.
Have the user that is creating a process also be a content manager and a administrator within Reporting Services.
