Simplify Windows Server 2008 Hyper-V migrations by providing
a shared 
storage LUN to all host servers. All physical hosts have
concurrent 
read and write access to all virtual machine images. Virtual
machine 
migrations do not require changing the storage connection
between 
hosts. Simple and intuitive to install and manage using any
SAN 
storage hardware.

PROF. POWERSHELL: On File

By Jeffery Hicks 

A common administrative task is to save the results of a
command or 
query to a text file. In the CMD shell the traditional
method is to 
use the console redirection characters > and >>.
You can still use 
these operators in PowerShell:

PS C:> get-process > processes.txt

There's nothing wrong with this technique in PowerShell. I
have yet 
to find a situation where it doesn't work.

But PowerShell has a cmdlet called Out-File which offers a
bit more 
flexibility. This cmdlet should be at the end of your
pipelined 
expression:

PS C:> get-process | where {$_.workingset -gt 10mb} |
out-file 
LargeProc.txt

Used without any parameters, Out-File will overwrite any
existing 
file with the same name. The cmdlet includes an -append
parameter
which will give you the same result as if you had used the
>> 
redirection operators.

However, the cmdlet also has a nice feature to keep you from

accidentally overwriting a file. You can use the -NoClobber

parameter:

PS C:> get-process | where {$_.workingset -gt 10mb} |
out-file 
LargeProc.txt -noclobber

When you use this parameter, if the file already exists
PowerShell 
will display an error message:

Out-File : File C:LargeProc.txt already exists and
NoClobber was 
specified.

The cmdlet also supports the -whatIf and -Confirm
parameters. These 
are also great "sanity-checkers."

By the way, you don't have to rely on the pipeline to use
Out-File. 
You can use its -InputObject parameter which will take the
specified 
object and send it to a file:

PS C:> $p = get-process
PS C:> out-file myprocs.txt -input $p

Finally, depending on your situation or the expression,
Out-File 
supports several encoding schemes. Use the -Encoding
parameter. 
The default is Unicode, but you can choose from ASCII, OEM,

Default, BigEndianUnicode, UTF7, UTF8, and UTF32.

SHARING PROBLEM: I have two PCs and the first PC uses Vista
and 
the other uses XP. I tried sharing using the same workgroup,
but 
it doesn't work. The XP PC can find the Vista PC, but the
Vista 
PC can't find the XP PC. What do I need to solve this
problem?

FULL SCREEN FOR DOS APP IN REMOTE DESKTOP: I have this old
MS-DOS 
program that when I run it locally on my Windows 2003
server, I 
can change the screen size to full screen (Alt+Enter). When
I do 
a remote connection to the server and run the program, if I
do 
Alt+Enter I get this error: 

The video device failed to initialize for fullscreen mode. 

What can I do to be able to run this program in full mode
when 
using it through a remote connection?

ADDING GROUP REMOTELY WITH USER PRIVILEGE: Would anyone
knows how 
to add domain group to local administrators group using 
administrator privilege on the remote PC running restricted

user privilege? Here is my command:

net localgroup groupname admingroup /add 

This has worked fine in administrator privilege, so how do I

deploy this command using admin right on workstations?

OUTLOOK EXPRESS UPDATE TO OUTLOOK: I am using Windows XP
Hhome, 
which came loaded on my e-machine. This XP version has
Outlook 
Express and my new phone contact list will not sync with
this 
product. I have also tried a copy of Microsoft Office 97
which 
contained an earlier version of Outlook and this version
would 
not sync.

What would be my best bet at this point? Download a copy of

Outlook from somewhere and hope that it will work with
Windows 
XP Home or completely switch my OS for one that includes
Outlook.
Should I look at Vista? Not so sure that I want to do that!


Has anyone had this problem in the past and if so what was
the 
cheapest fix?

PASSWORD DISABLE UBS PORTS: I'm looking for a way to disable

USB Ports in Windows XP SP 2, unless a password is entered
or 
authenticated user can access the ports. I can disable the
ports 
in Device manager, but I want to have security on the ports
so
authenticated user can use them and unauthenticated user
cannot 
use the port(s) for anything like a flash drive.
