On Tuesday I wrote about installing SharePoint Foundation
2010 on my home windows server, which also acts as a domain controller, and I
concluded by saying that I’d encountered performance issues as a result of that
(non-recommended) setup.

Turns out, the performance issues were a complete coincidence,
and everything is now running just fine.

The problem I was experiencing was that two of my three forward
DNS servers weren’t working correctly. Now that my
service provider has corrected their issue, everything is great.

For a small setup like mine, I’d say go ahead
and install SQL Server Express and SharePoint on the domain controller. It
works great!
