TFS on 64bit... Did I hear a NO CAN DO?

Sitting at a customer we just spedified a new server to host our TFS for internal use... We got our hands on a quad cpu Opteron with 8gb ram... of course we wanted to utilize the 8gb memory, and therefore told the outsourcing partner that they should roll on 64bit Windows 2003 r2.

As everyone knows, if they have been working with a outsourcing, its not the simplest task to get them to install anything within a nice timeframe.

So now we are sitting here, waiting for a reinstall of the server.. and had to apologize to the customer for being naive and trust our gut feeling, that all server products coming out of Redmond was 64bit enabled.

So to narrow it down:

Single server install: 32bit mode ONLY!!!

2 tier install: Application Tier 32bit and Data Tier 32/64bit.
