Remote Assistance offers over a VPN

In this day and age of Business 2.0, many organizations relay on VPN access for their users. You can offer them remote assistance. The process may be a bit more difficult. First off, you may have to use the clients IP address. You can ask the user for the IP address, but with Vista assigning both IPv4 and IPv6 addresses to each physical and virtual adapter, this could be frustrating for all parties. If you have access to the RRAS server the user is connected to, you can look up the properties of the connection. This should tell you the IP address to use in the offer. If DHCP Relay is enabled on the RRAS server, you may be able to look at your DHCP server for the IP address or use the name of the client.

Port issues on the local client, as well as the local network the client is on, will have an impact on your connection. I’ve found that DCOM port 135 seams to be the one most people are talking about. Here is the procedure to create an exception in the Windows Firewall for it (http://support.microsoft.com/kb/954386). Nothing can be done about a remote networks firewall settings. I found that Startbucks (Pay for use) and Panera Bread (Free Internet) allows me to remote access a VPN client.

Adding a Comment to a GPO with PowerShell

As I'm writing this article, I'm also writing a customization for a PowerShell course I'm teaching next week in Phoenix. This customization deals with Group Policy and PowerShell. For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material. I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO. This is a feature that many Group Policy Administrators may not be aware of. This past summer I attended a presentation at TechEd on Group Policy. One organization in the crowd had over 5,000 Group Policies. In an environment like that, the comment section can be priceless. I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

Return duplicate values from a collection with PowerShell

If you have a collection of objects and you want to remove any duplicate items, it is fairly simple. # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2 # Remove the duplicate values. $Set1 | Select-Object -Unique 1 2 3 4 5 6 7 What if you want only the duplicate values and nothing else? # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2 #Create a second collection with duplicate values removed. $Set2 = $Set1 | Select-Object -Unique # Return only the duplicate values. ( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers. The first command creates a collection with 2 duplicates of both 1 and 2. The second command creates another collection with the duplicates filtered out. The Compare-Object cmdlet will first find items that are diffe
