SBS 2008 DNS stops working for .uk, .eu and some other TLDs outside USA

Filed under: SBS 2008 — Rahul Patel @ 1:45 pm

In SBS 2008, when first installed or rebooted, DNS queries succeed, but after a period of about 1 day users report that they are unable to access some web sites. On inspection, it may be noticed that the inaccessible web sites are in the .uk and .eu Top Level Domains (TLDs) or certain other TLDs that are outside of the USA.

If left for several days, the problem may appear to resolve itself then re-occur after another day or so.

If the DNS server service is restarted, or the DNS cache on the server is cleared, then the problem is temporarily resolved but re-occurs after a day or so.

The cause of this problem is that in EU countries (and certain other TLDs outside the USA), nameserver records are typically cached for more than 1 day. SBS2008 has a cap on the maximum time that it will allow nameserver records to be cached, which defaults to 1 day. This default works fine in the USA but When the .uk and .eu records become stale, they are not deleted from the cache but are no longer returned as valid records. Therefore, they effectively prevent DNS lookups in those TLDs from succeeding until the records expire and are deleted from teh cache, or the DNS Server service is restarted.

The fix is to increase the maximum Time To Live (TTL) setting in the DNS server so that it recognises records older than 1 day. Experience has shown that setting the value to 4 days is usually enough, but the maximum setting is 30 days.

Solution

For a permanent work around, the MaxCacheTTL value needs to be changed to a value larger than the TLD TTL (Default value is 1 day, maximum value is 30 days). On SBS2008 there is no negative impact since this is the TTL for the cache of Resource Records. This is just the maximum value that it will be stored on DNS server. If the actual TTL is shorter, the shorter value will be used.

1. Start Registry Editor (Regedit.exe).
2. Locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
3.On the Edit menu, click New, click DWORD (32-bit) Value , and then add the following value:

Value: MaxCacheTTL
Data Type: DWORD
Data value: 0×69780 (432000 in decimal = 5 days)

4.Click OK .
5. Quit Registry Editor.
6. Restart the DNS server.

Shadow a Terminal Server Session Without Prompt for Approval

Filed under: Server 2003,Tips n Tricks — Rahul Patel @ 3:15 pm

Using windows 2003 and want to gain session access to another users session. Perhaps the person you are asking for shadow permission has an issue on his desktop and cannot figure it out,

To “Shadow” you have to know the session id of the user’s session that you want to view and or take over. Right click on your taskbar and select task manager. Go to Users and pick the users name and the session number should be located to the left of the name.
Shadow 0 and on the users session it will pop up a dialog box asking the other user for permission for you to access the session.

Of course this can be denied from the other user. Frustrating? :(

To shadow any other session, without a prompt, you would use the RDP-TCP Properties dialog, on the Remote Control tab, and clear the require users permission box.

To remote control the console (session 0) without a prompt for approval:

1. On the Terminal Services server, Start –> Run –>Gpedit.msc –> OK.

2. Navigate through Computer Configuration–> Administrative templates –> Windows Components –> Terminal Services.

3. Right-click Remote Control Settings and press Properties.

4. Select the Enabled option.

5. Select Full Control without user’s permission, under Options.

6. Press OK.

7. Exit the Group Policy Editor.

8. To force this local policy to update now, open a CMD prompt, type gpupdate /force, and press Enter.

When you establish a Remote Desktop session, you can connect to the console and remote control it:

1. Open a CMD prompt.

2. Type Shadow 0 and press Enter.

The user will NOT be prompted for permission.

Well this can be exploited and used in many wrong ways. So just be careful and use it wisely… :)

“Automated Troubleshooting Services” for Windows XP & Windows Vista

Filed under: Windows Vista,Windows XP — Rahul Patel @ 9:29 am

Common system maintenance tasks

Automatically detect and fix common maintenance problems such as broken desktop shortcuts, unused icons, disk volume errors, and incorrect system time display.

What it fixes…

* Problems with desktop shortcuts and icons
o Shortcuts on the desktop don’t work or are broken
o Desktop icons are broken or have not been used in 3 months
o Startup items don’t work or are broken
* System maintenance tasks
o Free up disk space by repairing disk volume errors such as bad sectors, lost clusters, cross-linked files and directory errors
o Free up disk space by removing error reports and troubleshooting history older than 1 month
o Set the correct system time and synchronize system clock with the time server
* You receive the following errors:
o Windows update error 0x80072F8F
o The item that this shortcut refers to has been deleted

How it works…
Microsoft Automated Troubleshooting Services scans your computer and detects the root causes of common problems, then
Automatically fixes the problems that it finds, and
Offers additional resources if the problem isn’t fixed

Windows 7′s “God-Mode” Hack

Filed under: Tips n Tricks,Windows 7 — Rahul Patel @ 3:15 pm

One irritation with Windows – even the well-designed Windows 7 – is that various control panels (Autoplay, Action Center, Administrative Tools, etc.), tend to be spread around the OS in multiple locations, making management more time consuming.

Some may have known this already, but a new tweak is just now gaining public attention, which allows all of these control panels to be congregated in a single folder. To get access to this “God-Mode” super folder, all you have to do is create a new folder named:

GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}

Once you’ve completed the (re)name the folder’s icon will switch to a control panel. You’ll then be free to start performing all the administration tasks you’ve been putting off.

Introduction to Google Public DNS

Filed under: My Knowledge — Rahul Patel @ 11:42 am

As web pages become more complex and include more resources from multiple origin domains, clients need to perform multiple DNS lookups to render a single page. The average Internet user performs hundreds of DNS lookups each day, slowing down his or her browsing experience. As the web continues to grow, greater load is placed on existing DNS infrastructure.

Since Google’s search engine already crawls the web on a daily basis and in the process resolves and caches DNS information, we wanted to leverage our technology to experiment with new ways of addressing some of the existing DNS challenges around performance and security. We are offering the service to the public in the hope of achieving the following aims:

* Provide end users with an alternative to their current DNS service. Google Public DNS takes some new approaches that we believe offer more valid results, increased security, and, in most cases, better performance.
* Help reduce the load on ISPs’ DNS servers. By taking advantage of our global data-center and caching infrastructure, we can directly serve large numbers of user requests without having to query other DNS resolvers.
* Help make the web faster and more secure. We are launching this experimental service to test some new ways to approach DNS-related challenges. We hope to share what we learn with developers of DNS resolvers and the broader web community and get their feedback.

Google Public DNS is a recursive DNS resolver, similar to other publicly available services. We think it provides many benefits, including improved security, fast performance, and more valid results. See below for an overview of the technical enhancements we’ve implemented.

Google Public DNS is not, however, any of the following:

* A top-level domain (TLD) name service. Google is not an operator of top-level domain servers (generic or country-code), such as Verisign.
* A DNS hosting or failover service. Google Public DNS is not a third-party DNS application service provider, such as DynDNS, that hosts authoritative records for other domains.
* An authoritative name service. Google Public DNS servers are not authoritative for any domain. Google maintains a set of other nameservers that are authoritative for domains it has registered, hosted at ns[1-4].google.com.
* A malware-blocking service. Google Public DNS does not perform blocking or filtering of any kind.

To try it out:

* Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers or
