Microsoft announced the release of four new edX online training courses for Microsoft Exchange Server 2016. If you plan to implement Exchange Server 2016 or Exchange Online, or if you want to make sure that your implementation was done right, the Exchange Server 2016 online training courses are for you.
Course offerings include:
Each Exchange course is targeted to the IT professional audience, with hands-on labs that reinforce student learning. Students are graded on completing each module, as well as on module assessment exams and a final course exam. A Certificate can be earned by completing each course with a passing grade. Courses are self-paced, allowing IT professionals to build Exchange skills at their own pace as their schedules permit.
The first course, CLD208.1x: Microsoft Exchange Server 2016 Infrastructure, is free. The remaining three courses are for-fee courses at $49 USD per course.
edX is a massive open online course (MOOC) provider that was developed by MIT and Harvard University. The Microsoft Learning Experiences team has created a wide range of online training courses for edX, and these four Exchange courses are the team’s latest Office releases. They are the first of seven courses that cover the core skills an Exchange administrator needs to proficiently design, implement and manage an Exchange 2016 and Exchange Online implementation.
Consider the following scenario that takes Microsoft Exchange Server 2013 as an example:
- The Mailbox server role is enabled in Exchange Server 2013.
- Exchange mailboxes use extended MAPI to communicate with the Exchange Server.
- The extended MAPI uses Microsoft RPC over HTTP (remote procedure call over HTTP) protocol.
- Many clients (such as mobile devices) are dropping connections to the Exchange Server.
In this scenario, the CPU usage on the Exchange server may reach 100 percent.\
Microsoft released Azure Active Directory Connect version 1.1.553.0 on June 26, 2017. More importantly, they published an important security advisory one day later.
Microsoft Security Advisory 4033453 – Vulnerability in Azure AD Connect Could Allow Elevation of Privilege explains,
The [ADD Connect version 1.1.553.0] update addresses a vulnerability that could allow elevation of privilege if Azure AD Connect Password writeback is misconfigured during enablement. An attacker who successfully exploited this vulnerability could reset passwords and gain unauthorized access to arbitrary on-premises AD privileged user accounts. The issue is addressed in the latest version (1.1.553.0) of Azure AD Connect by not allowing arbitrary password reset to on-premises AD privileged user accounts.
Microsoft highly recommends all customers update to version 1.1.553.0 or later to mitigate this vulnerability, even if you don’t use the optional password writeback feature. If you are unable to update immediately, the article above describes mitigation steps you can consider.
- If the AD DS account is a member of one or more on-premises AD privileged groups, consider removing the AD DS account from the groups.
- If an on-premises AD administrator has previously created Control Access Rights on the adminSDHolder object for the AD DS account which permits Reset Password operation, consider removing it.
- It may not always be possible to remove existing permissions granted to the AD DS account (for example, the AD DS account relies on the group membership for permissions required for other features such as Password synchronization or Exchange hybrid writeback). Consider creating a DENY ACE on the adminSDHolder object which disallows the AD DS account with Reset Password permission using Windows DSACLS tool.
There is a known issue with the MS16-072/KB3163622 patch. This update will break GPO’s with faulty rights. Examples: Drives appear on domain systems that should be hidden, mapping drives don’t work, and other typical GPO settings aren’t getting applied.
To resolve this issue, use the Group Policy Management Console (GPMC.MSC) and follow one of the following steps:
1. Add the Authenticated Users group with Read Permissions on the Group Policy Object (GPO).
2. If you are using security filtering (WMI), add the Domain Computers group with read permission.
Microsoft is pleased to announce the release of the new MCSA: Windows Server 2016 certification.
The new MCSA can be earned by taking and passing the following three exams:
- 70-740 – Installation, Storage, and Compute with Windows Server 2016
- 70-741 – Networking with Windows Server 2016
- 70-742 – Identity with Windows Server 2016
Exam 740 is scheduled for beta release in early October 2016, with the other exams following soon after.
Individuals who currently hold either an MCSA: Windows Server 2012 or MCSA: Windows Server 2008 certification will be able to upgrade to the new 2016 certification through a single, upgrade exam:
- 70-743 – Upgrade Your Skills to MCSA: Windows Server 2016
Exam 743 is scheduled for beta release in late July 2016.
MOC courses corresponding to all four Windows Server 2016 exams are scheduled for release in September 2016, while practice tests will be available shortly after each exam beta period ends.
New options for specialization and continuing education through the MCSE program will be announced later this summer.
If you want to use EUFI Boot with MDT 2013 Update X.
Don’t use DHCP Option 60/66/67!!!
DC01 = Windows Server 2008 R2 SP1
DC02 = Windows Server 2012
MDT01 = Windows Server 2012 R2
UEFI Client: Dell Laptop E5450
BIOS Client: HyperV Virtual machine with Legacy network adapert
DC1; MDT01 and DHCPServer all in Subnet1.
(IP Helper is set for DHCPServer for DHCP and for DC01 & MDT01 for DHCP and BootP – I checked serveral times if everything is right here)
UEFI Client and BIOS Client in Subnet2.
Situation1 — Using no DHCP Options and WDS running (IP HELPER-ADDRESS):
UEFI Client – Boots perfectly (contacting Server MDT01)
BIOS Client – Boots perfectly (contacting Server MDT01)
Situaion2 — Using no DHCP Options and WDS just running on MDT01:
UEFI Client – Does not boot (no error information is provided)
BIOS Client – Does not boot (no Bootfilename recieved)
Situation3 — Using DHCP Options(Option 66=”IP of MDT01″ Option 67=”\x86\wdsnbp.com”) and WDS just running on MDT01:
UEFI Client – Does not boot (no error information is provided)
BIOS Client – Boots perfectly (contacting Server DP1)
Situation4 — Using DHCP Options(Option 60=”PXEClient” Option 66=”IP of MDT01″ Option 67=”\x86\wdsnbp.com”) and WDS just running on MDT01:
UEFI Client – Boots perfectly (contacting Server DP1)
BIOS Client – Does not boot (taking hours to recieve dhcp options..)
On most switches you can configure ip helper-addresses. This is most time al ready configured for the use of DHCP.
Add the IP of the MDT server als ip helper-address:
description GEBRUIKERS VLAN
ip address 192.168.101.254 255.255.254.0 show
ip helper-address 192.168.25.6 (DC01)
ip helper-address 192.168.25.7 (DC02)
ip helper-address 192.168.25.30 (MDT01)
