I just gotSharePoint2010 Server installed and had a few lessons learned.

First, I followed the directions at:

Everything installed perfectly but when Central Administration came up the page was blank. So... I uninstalled and reinstalled SharePoint (4 times) and then went to bed. After a good nights sleep I realized it had to be an IIS issue.
