Ok this one is kinda lame… but alas, the fix is simple.
My ultimate goal was to perform a backup of a SharePoint WSS database on a Windows Server 2008 R2 server, with the intent of performing a database restore, to a new SharePoint 2010 Foundation Farm, so that I could perform a Database Attach Upgrade.
However… after installing SQL Server 2005 Management Studio Express on the WSS Server (this went okay), I could not login to the local SQL Server WID (Windows Internal Database) instance despite using the correct account/credentials. I used the correct method to connect to the WID of course (which, for your reading benefit/reminder is: \.pipemssql$microsoft##sseesqlquery). However, no matter what I did, I would get the following returned to me:
Figure 1 : Dude, you should totally let me in… Login Failed … really?
Alas, as you may have already become accustomed to, R2 and its security (Features?) are at play here. Despite the account HAVING access, I didn’t RUN SQL Server Studio Express “as Administrator”.
Alas, just do that, and your account will let you through just fine… Badabing!
