Case Study: 5
Proseware, Inc
Overview
General Overview
Proseware, Inc., is an international manufacturing company that has 3,000 users. Proseware
has a sales department, a marketing department, a research department, and a human
resources department.
Proseware recently purchased a small competitor named Contoso, Ltd.
Physical Locations
Proseware has two offices. The offices are located in New York and London. The offices
connect to each other by using a WAN link. Each office connects directly to the Internet.
Contoso has one office in Chicago.
Existing Environment
Active Directory Environment
The network of Proseware contains an Active Directory forest named proseware.com. The
forest contains a single domain and two sites named London and New York. Each site
contains two domain controllers that run Windows Server 2008 R2. The domain controllers
in the New York site are named DC1 and DC2. The domain controllers in the London site are
named DC3 and DC4.
All FSMO roles are hosted on DC3 and DC4.
The network of Contoso contains an Active Directory forest named contoso.com. The forest
contains five domain controllers and one site.
Exchange Server Organization
Proseware has an Exchange Server 2013 organization that contains two database availability
groups (DAGs) named DAG-NYC and DAG-LON. The DAGs are configured as shown in the
following table.
The certificate used for Exchange Server 2013 has a subject name of mail.proseware.com
and a Subject Alternative Name (SAN) of autodiscover.proseware.com.
Each mailbox database has three copies. All users connect to an active copy of the database
on a server in their respective office. Native data protection is implemented.
NTLM communication is used exclusively for Outlook Anywhere both internally and
externally.
Problem Statements
Proseware identifies the following issues:
• Users report that sometimes, they fail to access the free/busy
information of the other users. You also discover that some users fail
to retrieve Autodiscover settings.
• Users in the London office report that during a 24-hour WAN
outage, they could see only new users in the global address list (GAL)
from Outlook Web App.
• The manager of the human resources department in the New
York office cannot see new London office users in the GAL until
several hours after the help desk confirms that the users were
created.
• A hung MSExchangeOWAAppPool in Internet Information
Services (IIS) on EX1 causes all of the database copies to fail over.
Despite having the same CopyQueueLength and ReplayQueueLength
as the copies on EX2, the copies on EX3, which have a higher
activation preference, are activated, forcing user connections over the
WAN.
• A custom application named Appl recently malfunctioned and
sent hundreds of false positive email notifications that had a subject
of System Alert: Sales Database Reaching Capacity to all of the users
in the organization. While attempting to remove the email messages,
an administrator ran the Search-Mailbox -DeleteContent command
and erroneously deleted valid email messages from the mailboxes of
some executives.
Requirements
Business Goal
Proseware identifies the following business goals:
• Reduce the costs associated with using bandwidth on the WAN
links.
• Improve social media integration by using a Microsoft Outlook
app that will be deployed to all of the users in the sales department.
Planned Changes
Proseware plans to make the following changes:
• Implement a lagged copy for the mailbox database of the
executives.
• Implement an RBAC-linked role group for the administrators at
Contoso to manage the mailboxes of the Proseware users.
Technical Requirements
Proseware identifies the following technical requirements:
• End users must be notified after one hour if the email
messages that they send are not delivered.
• If mailbox database storage fails, the IT department must be
able to recover old email messages that were sent up to five days
earlier to the mailboxes of the executives.
• All new users hired at Contoso must have a user account in
contoso.com and an Exchange Server mailbox in proseware.com. All
new user accounts in contoso.com must have a user principal name
(UPN) that ends with proseware.com.
• Administrators at Contoso must be able to create and manage
recipient objects in the Exchange Server organization of Proseware by
using their existing contoso.com administrator account. All Contoso
recipient objects must reside in an organizational unit (OU) named
proseware.com/
Security Requirements
The Chief Security Officer (CSO) introduces the following security requirements:
• All Outlook users who connect from the Internet must use
Basic authentication only.
• All Outlook users who connect from the internal network must
use NTLM authentication only.
SLA Requirements
Due to productivity losses during some recent maintenance windows, the Chief Information
Officer (CIO) introduces a new service level agreement (SLA) requiring that all servers
entering or exiting a maintenance window must be taken in and out of service properly.
The SLA contains the following requirements:
• All mounted databases on the server undergoing maintenance
must be activated on another server.
• All message queues on the server undergoing maintenance
must be empty before maintenance can begin.
• The server undergoing maintenance must be prevented from
becoming a Primary Active Manager (PAM).
• Databases copies on the server undergoing maintenance must
not be activated while maintenance is occurring.
