VMware on AWS - How to restore NSX DFW firewall rules to previous state

Image
Customers who uses NSX day-in, day-out would like to have a point-in time restore functionality of DFW firewall rules. Many customer have a large footprints in VMC and make changes to DFW quite often. This feature was missing for long time and we could see its included in recent versions . Let's see how DFW configuration roll back works  NSX DFW configuration has versioning, and it is stored in the NSX Manager.  Every time when someone update DFW configuration, NSX creates one more version but keep storing the previous ones. You can rollback for previous config but reapplying it once again.  You can find the options under Networking & Security tab , > Security > Distributed Firewall . In the right side we see an Actions drop down. Choose View to get to the below screen.  Let’s go through the use case:  1. Original state- default config with no custom rules:  a. There are no saved configurations during last 30 days: In my existing test setup, with the current setting

Set up your target and communications infrastructure



Before you install the iSCSI initiator on any of your servers or workstations, you must have something to which the initiator will connect. This can be one of the enterprise class arrays, such as those available from LeftHand, EqualLogic, Dell, or EMC or, if you’re on a tighter budget and want to build your own array, a target running iSCSI target software, such as StarWind.

I recommend that, whenever possible, you use either a physically separate infrastructure or separate IP network/VLAN for your iSCSI traffic. By doing so, you simplify troubleshooting and configuration later on.

What is a Sysvol?

Image
SYSVOL is the acronym for the SYSFOL folder and all of the files stored in it on the Windows Operating System (OS). It stores the server’s copy of public data and files for the domain. These files consist of group or user policy information. The information stored in the SYSVOL folder is copied to all domain controllers on the respective domain. What are the SYSVOL Requirements? First, the SYSVOL folder has to be located on a Windows NTFS volume. The information stored in the SYSVOL folder is replicated on all domain controllers’ local disk via the File Replication Service (FRS), which must be installed for the operation to work properly. For network clients to access the SYSVOL tree’s contents, they must gain permission to access the NETLOGON and SYSVOL folders. The SYSVOL folder is used for a number of common networking applications, including adding a domain to an existing set or “Forest” of domain servers and locally creating a new logon script.

HOW TO EDIT THE BCD REGISTRY FILE

Image
The BCD registry file controls which operating system installation starts and how long the boot manager waits before starting Windows. Basically, it’s like the Boot.ini file in earlier versions of Windows. If you need to edit it, the easiest way is to use the Startup And Recovery tool from within Vista. Just follow these steps: 1. Click Start. Right-click Computer, and then click Properties. 2. Click Advanced System Settings. 3. On the Advanced tab, under Startup and Recovery, click Settings. 4. Click the Default Operating System list, and edit other startup settings. Then, click OK. Same as Windows XP, right? But you’re probably not here because you couldn’t find that dialog box. You’re probably here because Windows Vista won’t start. In that case, you shouldn’t even worry about editing the BCD. Just run Startup Repair, and let the tool do what it’s supposed to. If you’re an advanced user, like an IT guy, you might want to edit the BCD file yourself. You can do this

First, we will install the AD LDS Instance: 1. Create and AD LDS instance by clicking Start -> Administrative Tools -> Active Directory Lightweight Directory Services Setup Wizard. The Setup Wizard appears. 2. Click Next . The Setup Options dialog box appears. For the sake of this guide, a unique instance will be the primary focus.

The instance name will help you identify and differentiate it from other instances that you may have installed on the same end point.

Click Next to display the Ports configuration dialog box. 7. Leave ports at their default values unless you have conflicts with the default values. 8. Click N
