If you experience TF255437: Access is denied while installing TFS 2010 on a remote/separate data tier, likely, the setup account is not a member of the local Administrators group on that data tier machine.
[Google ranking skyrockets... ;-)] I'm a big fan of TFS/VSTS. However, there are a good pocket of folks who take issue with the way TFS handles or implements a certain feature. Well this is your chance to vent! I'm planning a presentation around the "Top 10 TFS/VSTS Hates and How to Alleviate Them"...or something along those lines. But I need your help. Post a comment below detailing your dislike. If it's legitimate, I'll highlight it in the presentation and [hopefully] provide an alternative, resolution, or work-around. Thanks in advance!
