SQL 2012 and Scale-out-file-server. Unable to Attach a Database

Working with a client with an installation of a Clustered SQL 2012 R2 servers with a Clustered File Server providing SMB3 shares to a Scale-Out-File-Server, we discovered that we could not attach an existing Database file. The error message is: Cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists. As a test, we can create a new database, verify that it exists, detach it, and then immediately try to re-attach it, and we get the error.

SMTP and Spamhaus blocking. What I learned today.

I was setting up a new client with an Exchange Server, and we discovered that we could not send email to any Microsoft Hosted email addresses.  Basically, to a subdomain of Outlook.com. All office 365 hosted email domain are subdomains of this address.  The issue was discovered when we tried to send an email manually using a text based email tool. The dialog looks like this (note that the unique data has been modified for privacy): blat.exe -body "this is a test" -to someone@ o365hosted .ca -server o365hosted .mail.protection.outlook.com -f me@legit.ca -s "Test of SMTP" -debug Blat v3.1.1 (build : Feb 27 2013 20:04:23) 32-bit Windows, Full, Unicode << 6:46 +0000 >>>putline>>> EHLO lab1-exch2013 << << ...
