If you ever need to look up which subnet is associated with which active directory site then just paste the below into vbs and pipe its output to a text file.
‘Get list of AD subnets
Set oRootDSE = GetObject(“LDAP://RootDSE”)
sConfigurationNC = oRootDSE.Get(“configurationNamingContext”)
Set oRootDSE = Nothing
sSubnetsContainer = “LDAP://cn=Subnets,cn=Sites” & “,” & sConfigurationNC
Set oSubnetsContainer = GetObject(sSubnetsContainer)
For Each sResult In oSubnetsContainer
aSNInfo = Split(sResult.cn, “/”)
If Instr(sResult.siteObject, “,”) = 0 Then
sSN = aSNInfo(0)
Else
sSN = aSNInfo(0) & “,” & _
Mid(Left(sResult.siteObject, Instr(sResult.siteObject, “,”) – 1), 4)
End if
wscript.echo ssn
Next
If you name the script listsites.vbs and want to output to a file call sitelist.csv and the script sites in a folder called “support” you can just run the following command line.
cscript c:\support\listsites.vbs > c:\support\sitelist.csv
Sometimes the Citrix licensing server doesn’t get accessed for a long time, maybe the admin leaves and is replaced and no-one made a note of the password. Suddenly, you can’t access the licensing server any more. What to do ?
If you have access to the disk sub system (ie.. the files) on the licensing server then it is possible to reset the admin password.
1. Open the “server.xml” file in C:\Program Files\Citrix\Licensing\LS\conf. If on Win2k8 you will need to open your editor as an admin. (Take a copy of the file first – if anything goes wrong you can simply copy the file back to restore the original settings).
2. Find the entry that looks something like this:
<user firstName=”System” id=”admin” lastName=”Administrator” password=”(ENC-01)LKJ338u98uxkllS(*U+ljljlja-$78923ghJgs” passwordExpired=”false” privileges=”admin”/>;
3. Erase the contents between the double quotes after “password=”
4. Enter a plain text password , for example password=”TemporaryPassword”
5. Change the passwordExpired value to be “true” and save the server.xml file.
6. Restart the licensing services or, at a push, reboot the server.
7. Log into the licensing console using user name “admin” and the password set above.
8. You will be prompted to change your password. The new password will be encrypted in the server.xml file.
To connect to the registry, we can list our possible choices using get-psdrive. The output will be similar to the below:
Name Used (GB) Free (GB) Provider Root
—- ——— ——— ——– —-
Alias Alias
C 240.39 57.60 FileSystem C:\
cert Certificate \
D 5.81 FileSystem D:\
E 3.64 FileSystem E:\
Env Environment
Function Function
HKCU Registry HKEY_CURRENT_USER
HKLM Registry HKEY_LOCAL_MACHINE
Variable Variable
WSMan WSMan
To mount the registry as a drive enter the command set-location: for example
set-location HKCU:
Note the colon at the end of the command.
You can then list the various items by using ls or Get-ChildItem. Setting the drive to the environment (Set-Location Env:) and then using Get-ChildItem lists all of the environment settings for the system
Want to have your powershell environment the way you want it each time you start PowerShell ?
Find the location of your default profile by typing profile$ at a PowerShell prompt. That will show you where your default profile script is held. For example:
C:\Users\philipflint\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1
Any statements that you add to this script will automatically be run each time you start PowerShell.
In this way you can call any plug ins or other scripts that you want.
Need to know the value of an environment variable on your computer such as the temp path ? Nothing could be easier.

Wnat to know who you are logged on as ?

Just access the advanced tab of computer properties and click on the “Environment Vaiables” button
