So I ran in to a copy of SQL 2005 Embedded today... first time I've seen it. It was on a MOSS install that some folks were testing, and they wanted the content moved over to our Production environment. No Problem, says I... I went to go make a backup of the Context DB to import in to the Production farm to move the content, but I couldn't connect to the DB server with my Management Studio.
Scratching my head with a perplexed look on my face, I loaded the Management Studio on the local server and tried opening it up there. No Dice... Apparently, it is an IP disabled version that only allow local named pipes connections, or something.
The only way I found to connect to the thing was by telling the Management Studio to connect to \\.\pipe\mssql$microsoft##ssee\sql\query
Not very intuitive... but it works...
