Windows 2000, XP and XP SP2 end of support

Posted in Active Directory, Client OS on March 26, 2010 by Mahmoud Magdy

As you may be aware, there are a number of Microsoft Windows versions which will go out of support during the coming year. We want to help customers avoid the risk of running unsupported products in their environment.
Windows 2000 Professional and Windows 2000 Server are approaching 10 years since their launch and both products will go out of support on July 13, 2010.
Windows XP was launched back in 2001. While support for the product will continue, Service Pack 2 will go out of support on July 13, 2010. From that date onwards, Microsoft will no longer support or provide free security updates for Windows XP SP2. Please install the free Service Pack 3 for Windows XP to have the most secure and supported Windows XP platform.
Finally, Windows Vista with no Service Packs installed will end support on April 13 2010. Please install the free Service Pack 2 for Windows Vista to have the most secure and supported Windows Vista platform.

How to reinstall ADRMS role on windows server 2008 R2?

Posted in RMS/Rights Management with tags on March 2, 2010 by Ahmed Elnaggar

We may face that we must remove ADRMS (Active Directory Right Management Services) from RMS server because of ADRMS role doesn’t work as expected or for any reason.

But, how we can do that and what are the steps we should follow to do that?

At first, we should remove ADRMS role from RMS server by default steps:

1 _ Server Manager

2 _ Remove roles

3 _ Uncheck Active Directory Right Management Services

4 _ Click next

The second and the importance step in this process, is that how to delete the ADRMS server from DC server? Why we need to do that? Because if we reinstall ADRMS role without removing it from DC, there will be conflicting in DC server. Because he already contains the SCP (Service Connection Point) of RMS server and he will not agree to register RMS server again with the same server name.

So, how to remove ADRMS server from DC Server?

1 _ At DC server, go to administrative tools, then go to Active Directory Sites and services

2 _ Click View

3 _ Go to RightManagmentServices folder

4 _ Delete it

At completing last step, you can now reinstall ADRMS role on RMS server.

Redirecting to OWA & HTTP to HTTPS Automatically

Posted in Exchange Server with tags , on February 23, 2010 by Karim Hamdy

Most Customers requires auto redirection from HTTP to HTTPS and to OWA virtual directory , here is the way on how to do it :

Redirecting to OWA Virtual Directory :

  1. Start the Internet Information Services (IIS) Manager snap-in.
  2. Expand the local computer, expand Sites, and then click Default Web Site.
  3. At the bottom of the Default Web Site Home pane, click Features View if this option is not already selected.
  4. In the IIS section, double-click HTTP Redirect.
  5. Click to select the Redirect requests to this destination check box.
  6. Type the absolute path of the /owa virtual directory. For example, type https://mail.contoso.com/owa.
  7. Under Redirect Behavior, click to select the Only redirect requests to content in this directory (not subdirectories) check box.
  8. In the Status code list, click Found (302).
  9. In the Actions pane, click Apply.
  10. For the new settings to take effect, open a Command Prompt window, and then type iisreset /noforce to restart IIS.

Redirecting to HTTPS from HTTP :

Open note pad create new file and paste the following code in it :

<!– beginning of HttpRedirect.htm file –>
<script type=”text/javascript”>
function redirectToHttps()
{
var httpURL = window.location.hostname + window.location.pathname;
var httpsURL = “https://&#8221; + httpURL ;
window.location = httpsURL ;
}
redirectToHttps();
</script>
<!– end of HttpRedirect.htm file –>

<!– beginning of HttpRedirect.htm file –><script type=”text/javascript”>function redirectToHttps(){var httpURL = window.location.hostname + window.location.pathname;var httpsURL = “https://&#8221; + httpURL ;window.location = httpsURL ;}redirectToHttps();</script>

<!– end of HttpRedirect.htm file –>

save it as “HttpRedirect.htm”

Now go to IIS Manager and create New Error Page with code 403.4

from response action click insert content from static location and from file path insert the Httpredirect.htm path

from Action Menu click edit feature settings , and select Custom Error Page and set the default page to the HttpRedirect.htm file path and that’s It.

Exchange 2010 ActiveSync Issue

Posted in Exchange Server on February 22, 2010 by Karim Hamdy

Today i’ve faced an issue regarding ActiveSync in Exchange 2010 , users cannot connect to ActiveSync after checking EventViewer the following error found :

Exchange ActiveSync doesn’t have sufficient permissions to create the “CN=<name>,OU=<OU Name>,DC=****,DC=****,DC=***” container under Active Directory user “Active Directory operation failed on <server>. This error is not retriable. Additional information: Access is denied.

with EventID 1053. after searching it appears to be this user does not have permissions on Exchange Servers . so here is how to resolve it.

Open Active Directory Users and Computers > Advanced Features > Open the user account Properties > Security > Advanced >Select Exchange Servers, and tick the Include inheritable permissions togglethen Apply and OK.

it seems to be this is a bug when upgrading from Exchange 2003 to Exchange 2010 although any new created users does not suffer this issue.
