What is the difference between the "Extract data-tier application" and "Export data-tier application" in the SSMS Options when right-clicking on a database?
Within Citrix XenServer...I want an internal network, not dependent on a physical NIC, that only the HyperVisor and virtual machines can see. I believe I want to implement a "Single-Server Private Network."
How do the VMs communicated with the Hyper-Visor? If I want to manage the Hyper-Visor from one of the VMs, how do I access it?
I know the other option is having a network associated with a physical NIC, but I don't want the LAN to be able to access that Network.
We have two domain controllers, HOST0 and HOST1. When HOST1 goes down, OWA is not available. When looking in exchange and running:
Get-ClientAccessServer -Identity HOST0 | FL
It shows HOST1 as the "Originating Server."
A) Why is OWA dependent on HOST1 when HOST0 is the Exchange Server?
B) Is there a way to change this behavior?
I broke my squid proxy. It stopped blocking HTTPS sites in the acl.denied_domains file, but still blocks the HTTP sites.
This was working till I edited my squid.conf file, and I do not have a backup.

I have used Piranha to setup fail-over for httpd. I set the servers the same, but one shows the VIPS and the other doesn't. Is this normal?

We have an SQL 2005 Server we need to upgrade the Hard Disks on. The most efficient way I can think of to do this is the following;
- Run a backup using Backup Exec on the D:\ Partition (This partition holds the SQL DATA Files)
- Disable the SQL Services from starting on start-up
- Reboot the Server into the RAID Controller
- Remove the old Hard Disks
- Insert the new Hard Disks
- Initialize the New Array
- Boot into the OS
- Assign the Drive letter D: to the new array
- Use backup exec to restore all the Data files to the D:\ partition
- Enable SQL Services on Startup
- Reboot the server
Is this the best way of doing this? Am I missing something?
