Windows Server 2008 R2 Best Practices in VMware vSphere 4.X

VMware, Windows Server
Be sure the virtual machine has at least 2GB of RAM. Hard drive for the virtual machine must be 20GB or larger. Single VCPU works better for Windows 2008, Because Windows 2008 uses high bit rate address space for context switching when compared with Windows 2003, which creates multiple cycles of high bit range contexts and these are better addressed by Single VCPU. (this again vary if it is a DB server). VCPU will get hit, when VMware have wide variety of hardware components attached to VM (Majorly Serial and Parallel COM ports, USB controllers, Sound Cards etc), if any of these components are not required, remove them and disable them from VM BIOS. Zeroed Thick: Space required for the virtual disk is allocated at creation time, hoVMwarever the data…

Linux, Windows Server
I was getting an error " The WinRM service failed to create the following SPNs: WSMAN/hostname; WSMAN/hostname. " at startup on Windows 2008 R2 Domain Controllers. Additional Data Log Name: System Source:  Microsoft-Windows-WinRM Event ID: 10154 Level:  Warning Solution: WinRM runs under " Network Service " account. You can eliminate this problem by giving Validated Write to Service Principal Name  permission to the NETWORK SERVICE using the ADSIEDIT.msc. This will allow WinRM to auto create the necessary SPNs on that domain controller. After granting this permission, re-sync all DCs and do a reboot to each domain controller where you did the change,  after that reboot you will see that the warning is gone and the required SPNs were created successfully. Steps: 1- Use ADSIEDIT.msc 2- Choose Default naming context and…
