Hyper-V Server 2008 - Error: 'The requested operation could not be completed due to a file system limitation'

When attempting to attach a VHD (or simply create a new virtual machine for that matter) by utilizing the Hyper-V manager on a remote computer (to manage Hyper-V Server 2008) I was having issues--I was receiving the error Error: 'The requested operation could not be completed due to a file system limitation' which was not too simple to figure out.

Turns out I was attempting to use a UNC path to point to the VHD (as I figured I would have to).  This is not the case--instead, in the management console on the remote machine I needed to use the local path on my actual Hyper-V server.

This resolved my issue.

Exchange 2003--How to force message stuck in 'Messages with an unreachable destination' to retry

I was in the middle of a migration from Exchange 2003 to 2010 and was troubleshooting public folder replication when I noticed my replication emails to the new public folder database were stuck in the unreachable messages queue.

The solution is to simply restart the SMTP service:

net stop smtpsvc
net start smtpsvc

Then the messages flowed out the appropriate connector.
