Configuring disks to use VMware Paravirtual SCSI (PVSCSI) adapters

PVSCSI adapters are high-performance storage adapters that can result in greater throughput and lower CPU utilization. PVSCSI adapters are best suited for environments, especially SAN environments, where hardware or applications drive a very high amount of I/O throughput. PVSCSI adapters are not suited for DAS environments.

This table shows the support matrix for use of Paravirtual SCSI adapters for data disks and boot disks for the various guest operating systems and ESX versions. Support shown in the table is from the listed ESX/ESXi version and later versions.

Because the default type of newly hot-added SCSI adapter depends on the type of primary (boot) SCSI controller, hot-adding a PVSCSI adapter is only supported for those versions that support booting from a PVSCSI adapter.

Paravirtual SCSI adapters also have these limitations:

  • Hot add or hot remove requires a bus rescan from within the guest.
  • Disks with snapshots might not experience performance gains when used on Paravirtual SCSI adapters if memory on the ESX host is overcommitted.

Active Directory Replication Status Tool

The Active Directory Replication Status Tool (ADREPLSTATUS) analyzes the replication status for domain controllers in an Active Directory domain or forest. ADREPLSTATUS displays data in a format that is similar to REPADMIN /SHOWREPL * /CSV imported into Excel but with significant enhancements.
Specific capabilities for this tool include:

    • Expose Active Directory replication errors occurring in a domain or forest
    • Prioritize errors that need to be resolved in order to avoid the creation of lingering objects in Active Directory forests
    • Help administrators and support professionals resolve replication errors by linking to Active Directory replication troubleshooting content on Microsoft TechNet
    • Allow replication data to be exported to source or destination domain administrators or support professionals for offline analysis

System Requirements

Supported Operating System

Windows 7, Windows 8, Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Vista, Windows XP

      • ADREPLSTATUS does not install on server core installs of Windows
      • Windows 2000 not supported due to lack of support for .NET Framework 4.0

    Domain membership requirements:

      • Must be joined to the Active Directory domain or forest you intend to monitor

    .NET Framework requirements:

When trying to activate you get 0xC004F074 with description "The Key Management Server (KMS) is unavailable"

Error:
image

The KMS host that is used is very probably a Windows Server 2008 KMS host that cannot standard activate Windows 7 and 2008 R2 machines.

When you do not have Windows Server 2008 R2 KMS host key have then you must have a Volume License agreement so that your request your Windows 7 and Windows 2008 R2 kms keys.

Resolution

Step 1:
-If the KMS host a Windows Server 2003 SP2 machine is you have the update from the KB article KB968915 install and restart the machine.
-If the KMS host a Windows Server 2008 SP2 machine is you have the update from the KB article KB968912 install and start the new machine.
-If the KMS host one Windows Server 2008 R2 machine is you have to install any further update.

Step 2:
You the new KMS host key import now. The commands are as follows:

1. Uninstall KMS license Key on host – slmgr.vbs /upk

2. Install Windows Server 2008 R2 KMS license key – slmgr.vbs /ipk <Your Key>

3. Activate KMS server online: slmgr.vbs /ato

4. Net Stop slsvc

5. Net Start slsvc

The clients can now activate

Defrag your Virtual Machines (VMs’)

Just like any other operating system, over time, a disk will become fragmented. Virtual machines are no different. The time that it takes for a disk to become fragmented depends on what data is being added to and removed from the virtual machine hard drive.

Why use MyDefrag instead of the standard Windows defragger?

  • Much faster.
  • Totally automatic, extremely easy to use.
  • Optimized for daily use.
  • Disk optimization, several strategies.
  • Directories are placed together.
  • Reclaims NTFS reserved areas after disk-full.
  • Maintains free spaces for temporary files.
  • Can defragment very full harddisks.
  • Can defragment very large files.
  • Can defragment individual directories and files.
  • Can be run automatically with the Windows Scheduler.
  • Can be used from the commandline.
  • Can be used as a screen saver.
  • Can be run from cdrom or memory stick.
  • Script language, can be customized.
  • Better voor VCB, VDR, DPM & Snapshots.

When you run MyDeFrag.exe with /verysilent it detect automatically the OS and then install x86 or x64 version from MyDefrag. It’s always installed at c:\program files. You can deploy it with MDT 2010 automatically when installing the OS. Or run it from a network share.

You can use Group Policy Preferences to schedule it.

Domain Upgrade van 2003 R2 naar 2008 R2

1. Installeer een Windows 2008 R2 server en zorg dat deze aan het huidige domain is toegevoegd.

2. Zorg er voor dat de eventuele DHCP role al overgezet is.

2. Kopieer van de 2008 R2 iso de adprep map naar c:\ van de eerste 2003 domain controller.

3. Voer het volgende uit: adprep /forestprep > c:\forestprep.log
image image
 
4. Check domain level
image
4. Voor nu het volgende uit adprep /domainprep
image  
5. Nu kun je de geïnstalleerde Windows 2008 R2 server upgraden tot domain controllers door middel van DC promo te draaien.

6. Draai dcpromo op desbetreffende servers. Gebruik hiervoor een account dat lid van is van de volgende groepen Schema Admins, Enterprise Admins, Domain admins.

7. Zet alle rollen over naar de 2008 R2 domain controllers
7.1 RID Master, PDC Emulator en Infrastructure Masters
image image

7.2 Active Directory Domains and Trust

image image

7.3 Active Directory-schema

De module Active Directory-schema installeren

  1. Klik op Start, klik met de rechtermuisknop op Opdrachtprompt en klik vervolgens op Als administrator uitvoeren.

    If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

  2. Typ de volgende opdracht bij de opdrachtprompt en druk vervolgens op ENTER:

    regsvr32 schmmgmt.dll
    image

  3. Klik op OK om het dialoogvenster te sluiten waarin wordt bevestigd dat de bewerking is gelukt.

  4. Klik in het menu Start op Uitvoeren, typ mmc en klik op OK.

  5. Klik in het menu Bestand op Module toevoegen/verwijderen.

  6. Klik onder Beschikbare modules op Active Directory-schema, klik op Toevoegen en klik vervolgens op OK

  7. En vervolgens doe Change Schema Master

 image image 

8. Check met het volgende command of alle FSMO rollen netjes zijn omgezet: netdom.exe query fsmo
image

9. Zo te zien zijn alle rollen netjes omgezet en kan ik win2k3r2x64 gaan demoten.

10. Zorg er voor dat de DHCP scope en overige servers de juiste dns instellingen hebben.

11. Voer dcpromo uit.

12. Nu nog even de win2k3r2x64 server uit het domein halen dan kan daarna de server netjes uitgezet worden.

Standaard domein naam

Wanneer je een Terminal Server omgeving hebt,  wilt je dat automatisch  de domein naam wordt in gevuld ipv WARD-TS01. Gebruikers moeten dit anders handmatig veranderen naar de domein naam.

Windows 2003 Server:

In windows 2003 moet je dit doen door middel van een register waarde aan te passen:
HKLM \ Software \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon
Voeg een nieuwe string value toe genaamd DefaultDomainName en geef als waarde je Domeinnaam.

Windows 2008 Server:

In Windows Server 2008 is deze instelling opgenomen in de Group Policy Object.
Computer Settings \ Administrative Templates \ System \ Logon \ Default domein voor aanmelding
Hier moet je domeinnaam invullen.

Dit is een stuk handiger als steeds te klikken.
