IIS 7 Authentication: What happened to the IUSR_MachineName account?

In previous versions of IIS, the IUSR_MachineName account is created for anonymous authentication. This is an actual user account created on the server (a domain account can be used in domain environments), and like all user accounts— it has a SID, and an account password with the accompanying management costs and risks.

One of the resulting annoyances (for me): when you install IIS first and then change the computer name, the computer name and the MachineName in IUSR_MachineName account don't match.

IIS 7 gets rid of the IUSR_MachineName account in favor of a built-in IUSR account that's guaranteed to have the same SID on all computers. This ensures ACLs copied from one web server to another work, domain accounts are no longer required, and applications can be easily deployed across multiple web servers. The IIS_WPG group (for IIS Application Pool identities) is replaced by the built-in group IIS_IUSRS.

Note: The IUSR_MACHINENAME account isn't completely gone— it is used for anonymous authentication to FTP, and gets created if/when you install FTP.

Creating a Dynamic Distribution Group for all mailboxes on a Database

I posted about this in Adventures with OPATH: some annoyances if you're used to LDAP, shortly after Exchange Server 2007 RTMed (Yes, it has really been that long... ). Here's a quick recipe to create a Dynamic Distribution Group to include all mailboxes on a database.

$DB = (Get-MailboxDatabase "SERVER\Storage Group\Mailbox Database").distinguishedName

New-DynamicDistributionGroup MyGroup -RecipientFilter {Database -eq $DB} -RecipientContainer "DC=MyDomain,DC=com" -OrganizationalUnit "OU=Distribution Groups,DC=MyDomain,DC=com" -RequireSenderAuthenticationEnabled $false

The first step gets the distinguishedName of the mailbox database in a variable called $DB.

Parameters:
- OrganizationalUnit: Specifies the container/OU where the group will be created
- RecipientContainer: Specifies container to pick up recipients from. If not specified, this gets set to the same value as the OrganizationalUnit parameter (the OU/Container where the group is created), and the filter may not return the expected recipients (or worse— may not return any recipients at all... )
- RequireSenderAuthenticationEnabled: As discussed in 'New Distribution Groups do not receive internet email by default', new groups do not receive internet email (that is, email from unauthenticated/anonymous senders)) by default. If you want the group to receive internet email, set this to $false.

Controlling OOFs per domain and per mailbox

OOFs can be controlled per domain using Remote Domain settings. By default, setup creates the default Remote Domain for address space *. (As with Connector namespaces, * translates to all domains for which Exchange isn't authoritative/has an Accepted Domain for, and doesn't have an explicit Remote Domain for).


Figure 1: Remote Domains allow control of OOF messages to the internet or specific domains

The choices:
None: OOFs are disabled for the remote domain.
External: Allows only external OOFs to be sent to the remote domain. OOFs created using legacy Outlook clients and those sent by Exchange 2003/2000 servers will be not be allowed. If blocking OOFs to external domains in Exchange 2003/2000, this allows you to restrict legacy Outlook clients from sending OOFs, but allow Outlook 2007/Exchange 2007 users to send external OOFs.
ExternalLegacy: Allows external and legacy OOFs to be sent to the remote domain.
InternalLegacy: Allows internal and legacy OOFs to be sent to the remote domain.

Allowing Internal OOFs to Remote Domains

The InternalLegacy setting sends internal OOF messages to a Remote Domain. If verbiage or content of internal OOFs isn't something you want to share with the outside world, do not use this for Remote Domains.



The InternalLegacy option can be useful in distributed organizations with multiple address spaces and multiple email systems, or specific cases where you may want to share such information with a trusted organization.

Controlling OOFs per-mailbox

Besides the settings in Remote Domains, you can also control external OOFs per-mailbox. This is done using the Set-Mailbox cmdlet. The ExternalOofOptions parameter defaults to External. You can change it to InternalOnly to restrict a mailbox user from sending OOFs outside the organization:

Set-Mailbox foo@mydomain.com -ExternalOofOptions InternalOnly

Released: RDP Client for Mac 2

If you're a Mac user, connecting to Windows servers and desktops just got a lot better. The much anticipated RDP Client for Mac 2 has been released.

The RDP Client for Mac 2 is available in 8 languages (including English). Download it here.

New features include multi-session support, new Network Level Authentication (NLA) that completes authentication before establishing an RDP session, a more Mac-like UI, wide-screen resolutions, automatic reconnects, and printing support (ability to print documents from a RDP session to the locally attached printer on your Mac).

This comes close on the heels of Microsoft Messenger for Mac 7 (M3?), released in late April. It's compatible with Office Communications Server 2007, and includes Bonjour support— go to the Office for Mac team blog to find out more.

While we're still on the subject, have you looked at Office 2008 for Mac? If you're already using it, let me know what you think!

Released: ISA 2006 Service Pack 1

ISA Server 2006 SP1 has been released. SP1 brings some new features, and improvements such as support for SAN certificates. Download SP1.

New features:

• Configuration Change Tracking: Registers all configuration changes applied to ISA Server to help you assess issues that may occur as a result of these changes.
  
• Test Button: Tests the consistency of a Web publishing rule between the published server and ISA Server.
  
Traffic Simulator:Simulates network traffic in accordance with specified request parameters, such as an internal user and the Web server, providing information about firewall policy rules evaluated for the request.

• Diagnostic Logging Viewer: Now integrated as a tab into the ISA Server Management console, this feature displays detailed events on packet progress and provides information about handling and rule matching.

Improvements for existing features:

• Support for integrated NLB mode in all three modes, including unicast, multicast, and multicast with Internet Group Management Protocol (IGMP). Previously, ISA Server integrated NLB-supported unicast mode only.
  
• Support for use of server certificates containing multiple Subject Alternative Name (SAN) entries. Previously, ISA Server was able to use either only either the subject name (common name) of a server certificate, or the first entry in the SAN list.
  
• Support for KCD cross-domain authentication. Credentials from users located in a different domain than the ISA Server, but in the same Forest, can now be delegated to an internal published Web site by using KCD .
  
• Support for client certificate authentication in a workgroup deployment. This removes the requirement to map each client certificate to an Active Directory® directory user account when forms-based authentication is used as the primary authentication method and client certificates are used as the secondary method.

SP1 fixes the following issues:

• 894679 Users who do not have the appropriate permissions can receive restricted content from ISA Server 2004

Monitoring Exchange Server 2007 Performance: Perfmon counters and thresholds

Monitoring mission-critical services such as email is a necessity in most organizations. Whereas monitoring software like Microsoft SCOM can use Exchange monitoring expertise and rules encoded in Management Packs, and many third-party monitoring solutions ship with some embedded knowledge, if you're setting up a monitoring system or creating a home-grown app to do so, you need to know what to monitor.

I was fortunate enough to (sort of) take a course on Exchange performance monitoring at my previous employer, and get a lot of input on the subject from some great minds in the business. The resulting fondness for performance monitoring and performance counters is probably understandable.

If you share my enthusiasm for performance monitoring, here's some documentation and guidance you may find very useful:

- Monitoring Mailbox Servers
- Monitoring Hub Transport Servers
- Monitoring Client Access Servers

Exchangepedia turns 4!

Yes, Exchangepedia Blog is 4 years old today! Exchangepedia saw its first posts in June 2004. Hundreds of posts, 1 major Exchange release and 2 service packs (Exchange Server 2003 SP2 and Exchange Server 2007 SP1) later, it's great to look back at some of the stuff I've enjoyed writing, and some posts that got great feedback.



Feedback?
Feedback about the content and other aspects of Exchangepedia is always welcome and valued. Sorry, I'm unable to reply to each comment and cannot respond to each question, I do read all of them.

With that in mind, if you have any feedback on the posts, screenshots, "screencasts", scripts, design, content, topics, etc., please leave a comment.

- Has it been useful for you?
- Is it interesting to read?
- Do the posts here help you resolve any deployment/operations issues or clarify a concept?
- Are there additional topics you'd like to see covered here?
- Would you like to see any changes to anything on the blog - the content, the design, anything? (Except for adding a Search box, which is on the top of my list... )?

In the 5th year of its existence, I do intend to finally move Exchangepedia off the Blogger platform, and no— it being a Google product really has nothing to do with it. I love Wordpress, and would like to play with Joomla! or Community Server as well— time permitting. Migrating all the content, comments, and keeping existing URLs is a bigger and more complicated project than I thought.

Finally, the traffic has been rising steadily, and the existing server that's been hosting this blog since day 1 seems to be limiting. I would really love to move off the 400-Mhz. Pentium 3 box that's been serving this site (and quite a few other web sites, including some Wordpress ones)— maybe to a Windows Server 2008 web server running inside a Hyper-V virtual machine. If my tests with Wordpress on Windows 2008 go well, I will hopefully be able to do that soon.

Meanwhile, if you know of a "Migrate This" button I can click on to migrate all posts, comments and URLs from Blogger to Wordpress, please email me!

Save XP, Rick Mercer Style

It's June 30th! I had the date marked because of two reasons. The first one has to do with Windows XP, and if you haven't heard enough already, CBC's Rick Mercer has his own view of how to save Windows XP. Caution: May not be entirely work-safe for some.



The second reason's coming up in a post after the break, and it has absolutely nothing to do with Windows XP or Windows Vista!

Released: Windows Server 2008 Hyper-V

While I was away yesterday, Windows Server 2008 Hyper-V made its public debut (RTMed in Microsoftese). I know what you're thinking: Let the Microsoft PR storm begin, VMWare has a better virtualization product, and other unbloggable thoughts... :).

I've been using Hyper-V for a few months now, and all I can say is— it's been a great experience way before RTM, and I am impressed! Of all things Hyper-V that impress me, I'm blown away by the performance - it flies! This, on a desktop class machine (one that meets the CPU and other requirements, of course, but poorly-configured to be used as a server/Hyper-V box that's running quite a few virtual machines).

Next, the simplicity and ease-of-use. As InfoWorld's Randall C. Kennedy puts it:

As with most Server 2008 "roles," enabling Hyper-V was a simple matter of ticking a check box in Server Manager and picking a NIC for use by the virtual network manager.

Read more of Randall's review in Test Center review: Microsoft's Hyper-V does the trick.

Scott has a post with plenty of links to Hyper-V resources and blog posts— Hyper-V has RTM'd and is Available!

As Scott mentions in the post, Microsoft will have a support statement about Exchange Server and virtualization 60 days from Hyper-V RTM. This was announced at TechEd IT Pro in Orlando little over 2 weeks ago.

Exchange Quick Audit: mailboxes created in last 7 days

I remember writing plenty of scripts to report on different things such as user accounts created every week/month, user accounts modified, accounts disabled, etc. for SOX compliance. Some of those scripts used to be rather long, and in hindsight— involved a lot more lines of code than an administrator should have to write. Although I had a lot of fun (and still do... albeit with PowerShell), I would totally understand if you said you never wanted to hear about things like Wscript, VBScript, WSH, COM objects, ADSI, and WMI ever again.


Let's take a look at how the shell (EMS) makes it so easy.

In this examnple, we need to get a list of all accounts created in the last 7 days. When a user account is created, its whenCreated attribute gets stamped with the time of creation. Here's how it can be used:

Get-User -resultsize unlimited | where {$_.WhenCreated -gt (get-date).adddays(-7) | ft Name,whenCreated -Autosize

Similarly, when an AD object is changed, it's whenChanged attribute gets stamped with the time the change was made. This makes it easy to determine which objects were changed in a given period, a useful tool for auditing/reporting as well as troubleshooting. In the following example, we determine if any Receive Connectors were changed in the last 7 days.

Get-ReceiveConnector | where {$_.whenChanged -gt (get-date).adddays(-7)}

Another frequently required and requested report— how do I get a list of mailboxes that haven't been accessed in the last X days. Let's use 100 days as the value here:

Get-MailboxStatistics -resultsize unlimited | where {$_.LastLogonTime -lt (get-date).AddDays(-100)} | ft displayName,lastlogontime,lastloggedonuseraccount,servername

Or mailboxes that have never been logged on to:

Get-MailboxStatistics -resultsize unlimited | where {$_.LastLogonTime -eq $null | ft displayName,lastlogontime,lastloggedonuseraccount,servername

Note, you can filter mailboxes by Database or ServerName to restrict the results to a more manageable size.

Next, let's list mailboxes disabled in the last 14 days:

Get-MailboxStatistics | Where {$_.DisconnectDate -gt (get-date).AddDays(-14)} | ft displayName,ServerName,DatabaseName,TotalItemSize -Autosize

Modifying Display Templates and additional attributes

Recently got a question about customizing the GAL and my previous post that talks about it: "HOW TO: Modify Display Template to make default email address appear in Address Book/GAL".

The new Details Template Editor in Exchange 2007 (in EMC | Tools) makes it much easier to modify templates and give your GAL the kind of look you want (short of adding that 5 Mb. purple bitmap file as a background and an extra-large company logo perhaps... :). Screenshots and more information about Details Templates can be found in Managing Details Templates.

So, you're trying to customize the properties pages of your address lists and want to add an attribute such as ipPhone. You don't see the attribute you're looking for. Can you add additional attributes to the list? Or should you? Dave Goldman explains in Adding attributes to the Exchange details templates.

Exchange Server 2007: Listing Exchange ActiveSync users and device information

In How to get a list of Exchange ActiveSync users we list EAS users on Exchange 2007. Some users may have more than 1 device, or perhaps the user simply got a new smartphone and the old device partnership has not been removed.

Output from Get-ActivesyncDeviceStatistics -mailbox foo@somedomain.com:

Here's a a quick code snippet (it can probably be scrubbed up a little... ) that will list users and all their devices, along with first sync and last successful sync times:
