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

How to Configure IIS to Host a Web Page







IIS (Internet Information Services) is an easy to use web server from Microsoft. It is not installed on Windows XP Professional by default. However, it is installed when the user upgrades from Windows NT or Windows 2000 to Windows XP Pro. IIS can be installed as follows:

Click Start, click Control Panel, and double-click Add/Remove Programs.
 The Add/Remove Programs application starts. 

In the left column of the Add/Remove Programs dialog box, click Add/Remove Windows Components.
When the Windows Components Wizard appears, click Next.
In the Windows Components list, select IIS.
Click Next and follow the instructions.





inetmgr


Install in Windows 7:
  1. Click the Start button (or the Windows button) then Control Panel. 
  2. Click Programs and Turn Windows features on or off under Programs and Features. 
  3. In the list that appears, check Internet Information Services and Internet Information Services Hostable Web Core, click OK, and wait for it to install. 


IIS allows the user to host a web page on his/her own computer that others using the DNSname or the IP address of the PC on the network can access. The IP address can be found by using the command ipconfig in command prompt.


The IIS is configured with the IIS snap-in, previously called the Internet Services Manager. This can be accessed in one of three ways:


Method 1:
  • From the Start menu, select Settings then Control Panel 
  • Open Administrative Tools 
  • Open Internet Information Services 


Method 2:
  • Right click My Computer on the desktop 
  • Select Manage to open the Computer Management console 
  • Select Internet Information Services under Services and Applications 


Method 3:
  • From the Start menu, select Run 
  • Type inetmgr and run the command 


The Internet Information Services snap-in provides server management options to control content and access to the Web or FTP sites. For example, if a developer is testing a site before uploading it to an intranet or the Internet, he/she can use this tool to test the settings exactly as they will be on the final server. When the IIS is installed, a default website and FTP site are created. Information can now be published on these default sites by following the steps outlined below:
To Publish Content on a Web Site
Create a home page for the website with any web page design tool
Name the home page file Default.htm or Default.asp
Copy the home page into the default Web publishing directory for IIS, also called the home directory, located in inetpubwwwroot or inetpub/wwwroot on the main partition (usually C:).
If the network has a name resolution system (typically DNS), then visitors can simply type the user’s computer name in the browser’s address bar to reach user’s site. If the user’s network does not have a name resolution system, visitors must type the computer’s numerical IP address.
To Publish Content on the FTP Site
Copy or move the files into the default FTP publishing directory. The default directory that Setup provides is inetpubftproot.
If the user’s network has a name resolution system (typically DNS), visitors can type ftp:// then the computer name in their browser’s address bar to reach the user’s site. If the user’s network does not have a name resolution system, visitors must type ftp:// and the computer’s numerical IP address.


With Windows XP Professional, users can host one website and one FTP site on a single computer. To host multiple web or FTP sites on a single computer, consider upgrading to a server product.

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
