DNS Scavenging

Scavenging is a feature that will remove expired records based on their time stamps.
Scavenging is not enabled by default.
Scavenging will NOT remove statically configured records, the ones you manually create unless you run dnscmd /AgeAllRecords, which will stamp them making them eligible for scavenging (more below on this). Without running this command, DNS will scavenge dynamically updated records that have reached their time stamp. To look at the time stamps of a record using Windows 2003 DNS, put the DNS console “view” in the menu to Advanced View, then look at the individual record properties, and you will see the time stamp. If using Windows 2008 or or newer, it will show up in the console as a separate column.

Vulnerability in SSL 3.0 Could Allow Information Disclosure

  • Disable SSL 3.0 and enable TLS 1.0, TLS 1.1, and TLS 1.2 in Group Policy You can disable the SSL 3.0 protocol that is affected by this vulnerability. You can do this by modifying the Turn Off Encryption Support Group Policy Object.
    1. Open Group Policy Management.
    2. Select the group policy object to modify, right click and select Edit.
    3. In the Group Policy Management Editor, browse to the following setting:Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Explorer Control Panel -> Advanced Page -> Turn Off Encryption Support
    4. Double-click the Turn off Encryption Support setting to edit the setting.
    5. Click Enabled.
    6. In the Options window, change the Secure Protocol combinations setting to “Use TLS 1.0, TLS 1.1, and TLS 1.2“.
    7. Click OK.
  • Disable SSL 3.0 and enable TLS 1.0, TLS 1.1, and TLS 1.2 in Internet Explorer You can disable the SSL 3.0 protocol that is affected by this vulnerability. You can do this by modifying the Advanced Security settings in Internet Explorer.To change the default protocol version to be used for HTTPS requests, perform the following steps:
    1. On the Internet Explorer Tools menu, click Internet Options.
    2. In the Internet Options dialog box, click the Advanced tab.
    3. In the Security category, uncheck Use SSL 3.0 and check Use TLS 1.0, Use TLS 1.1, and Use TLS 1.2 (if available).

How to Autoredirect a Page with Java or HTML

<html>
<head>
<title>A web page that points a browser to a different page after 2 seconds</title>
<meta http-equiv="refresh" content="2; URL=http://example.com/services/computing/">
<meta name="keywords" content="automatic redirection">
</head>
<body>
If your browser doesn't automatically go there within a few seconds, 
you may want to go to 
<a href="http://example.com/">the destination</a> 
manually.
</body>
</html>

…or it can done with JavaScript. This JavaScript example opens the new site in a new browser window after a 4.5-second (4500 ms) delay:

 <script language="javascript" type="text/javascript">
     <!--
     window.setTimeout('window.open("http://example.com/","newsite")',4500);
     // -->
 </script>

OWA Showing Blank Page

I am presented with the OWA Authentication page and enter my credentials and then it throws an “HTTP 500” error instead of opening the mailbox.

You tried to issue an “IISReset /NoForce” and even rebooted the server and still see the symptom.

So the issues is typically caused by the “Microsoft Exchange Forms-Based Authentication” service being in a stopped state. Starting the service immediately fixes the issue.

Equallogic Fun

Well I got some new hardware in. This has allowed me to play with some various configuration settings – settings that I wish I had known about some years earlier.

Above, you can see where I’ve got two members, ONR1, and ONR2 in differing RAID formats, connected (below) the same storage pool,

Below you can see the volumes setup on the storage pool.

After some time, you’ll see that the volumes redistributed across the two sans.

Pretty sweet eh?

USING SYSPREP WITH VIEW

Occasionally it is necessary to use Sysprep instead of Quickprep when creating a desktop pool with View. This usually is because of some legacy software requiring unique local computer identifiers (SIDs). I recently got asked about it because of some older antivirus software that needed it to centrally manage its in-OS agents.A comparison of the two customization techniques can be found in the View Administration Guide on pages 95 and 96. KB article 2003797 gives a quick table of the differences:

Function QuickPrep Sysprep
Removing local accounts No Yes
Changing Security Identifiers (SID) No Yes
Removing parent from domain No Yes
Changing computer name Yes Yes
Joining the new instance to the domain Yes Yes
Generating new SID No Yes
Language, regional settings, date, and time customization No Yes
Number of reboots 0 1 (seal & mini-setup)
Requires configuration file and Sysprep No Yes

To setup and deploy a pool using Sysprep the high-level steps are as follows:

  1. Copy the Sysprep files to the vCenter server (Note that this is only required for Windows XP as Windows 7 comes with sysprep). Full details on this are in KB article 1005593.
  2. Create a Guest Customization Specification in vCenter.
  3. Add a desktop pool and tell it to use sysprep and the guest customization spec you have created.

Create a Guest Customization Specification

  • In vCenter from the Home page select the option for Customization Specification Manager.
  • Add a New customization and on the Properties page enter a name. DO NOT use a custom sysprep answer file.
  • Continue through the wizard until the Computer Name page. Set this to use the virtual machine name.
  • Step through the wizard entering license keys, administrator password, time zone, etc until you get to the Network page.
  • Make sure you leave the network at the default of typical settings. This will then use DHCP
  • .
  • On the Workgroup or Domain page leave this as the default. Any domain / administrator information entered here is not used. Instead the VM is joined to the domain using the guest customization settings defined in the pool settings through View Manager.
  • On the last page Operating System Options make sure that the Generate New Security ID (SID) is checked. After all the whole reason we are using Sysprep is because unique SIDs are required for our use case.
  • Finish the wizard.

Add a desktop pool

  • In View Manager add a desktop pool as you would normally. The only deviation from using Quickprep comes on the last page for Guest Customization.
  • Select the Domain. This list (normally only one in most environments) is what you defined when you configured the vCenter server in View Administrator and defined the Domains for View Composer. This settings is what will control which domain is joined and which credentials are used when customizing the linked clones.
  • Select the appropriate AD container as normal.
  • Select the option to Use a customization specification (Sysprep) and select the spec you created earlier.
  • When you complete the wizard your pool should deploy although provisioning can be a bit slower than using Quickprep especially as there is an additional reboot of the linked clone required.

So what are the steps that take place when View customizes with Sysprep?

  1. Once the linked clone disks have been created, View Manager puts the VM into the Customizing state.
  2. View Manager calls the vCenter API customizeVM_Task to customize the VM with the customization specifications.
  3. View Manager powers on the linked clone.
  4. Inside the Guest OS on the linked clone, the View Composer Agent sees that it is starting for the first time and calls NetJoinDomain with the machine password cached on the internal disk.
  5. The machine is now joined to the domain.
  6. Sysprep is now run on the linked clone from within the guest.
  7. The  View Composer Agent waits for Sysprep to finish before notifying the View Agent that customization is complete. Then the View Agent sends a message to the View Manager server.
  8. The View Manager Server powers off the clone and takes a snapshot of the customized, powered off clone (to give us our refresh state).
  9. View Manager puts the linked clone into the Provisioned state. If the VM is then powered on, it moves into the Available state.

How to Update Force10 S50n Firmware

Here is the Firmware FTOS-SB-8.4.2.7.bin

You’ll need a tftp program installed on your desktop.

Copy the new firmware to your tftp server folder.

Here is the command to upgrade the system

upgrade system tftp://192.168.1.xxx/FTOS-SB-8.4.2.7.bin

Output will look like this:

Force10#upgrade system tftp://192.168.1.xxx/FTOS-SB-8.4.2.7.bin

You can use the serial cable or ssh into the switch to do this operation.

Don’t forget to write, before issuing the reload command.

Here’s an example of my running config:
