Why?
So I get back from annual leave and I can't check-out / check-in any files in a Visual Studio 2010 project. All my colleagues can.

What?
Rather silly I know and the solution is one of those obvious ones for those that know how but for those who can't remember, then it can take a while.

How?

What?
I installed Business Intelligence Development Studio 2008 (BIDS) and connected it to a Team Foundation Server 2010 (TFS) instance and set my working local folder to my home directory. When the rest of my colleagues installed it however, they decided to use a common local directory for all workstations so configuration files would not need to be modified.

So?
Once installed, my BIDS install would continuously check-out files and store these in the home directory. I tried the general settings (Tools > Options) but to no avail.

How?
