SYSVOL FSR problems

File Replication Service (FRS) is used for synchronising the SYSVOL shared folders on domain controllers and for synchronising DFS link targets on servers running Windows.
 
Recently i had a DC that was strangely not replicating policies over a WAN link.
 
after scratching our heads and looking over very long and boring event logs from the server and SCOM i download a tool called SONAR, free download from Microsoft  <HERE>.
 
this spotted strangely the SYSVOL share had been unshared…….. Strange but true,,, anyway without this tool it would have taken several hours longer and more scratching my head over event logs.
 
Download it and see for your self.  Worth its weight in gold.

Boot from VHD

 
One of the hidden gems in the new Windows BETA offering from Microsoft is one that allows you to boot from a VHD file.
Windows 7 Beta and Windows Server 2008 R2 Beta support booting into the OS from a VHD file attached to Virtual PC or Hyper-V.
Follow the simple steps below and be amazed how easy it is…….
 
Right-Click on “Computer” and select “Manage.” From there expand “Storage” and right-click on “Disk Management” and select “Create VHD.”
 
 
Select what VHD you would like to boot from and select the VHD size and click OK.
 
 
Once you have created the VHD file, boot your machine with the OS DVD in the drive and choose “Install Now,” then press SHIFT+F10 to get the command prompt. Type the following:
 
 
When you return to the installation procedure, you will see a 20GB partition.You will be warned that you cannot boot from this volume – ignore this message and continue the install.
 
When you boot up, it will make Windows 7 the default boot option. You can change this using bcdedit
 
This is a great way installing multiple copies of Windows 7 or Windows Server 2008 R2 on a machine or storage area network without creating multiple partitions
 
To give you an idea of where this could be use useful take a school that has hundreds of students PC’s that could share the same VHD file that would be write protected and simply refreshed every time the machine is rebooted.  or a call center that used windows during the day for office based tasks and then swop’s to Linux during the night for data mining……. the possibilities are endless, WELL done Microsoft!
 
Have a play and enjoy… I think you will be presently surprised how cleanly this works.

Active Directory Health Check

This blog post outlines a basic procedure for validating the health of your domain and is a good practice for iterative maintenance and an excellent pre-check before doing any potentially dangerous domain operations.

Before doing anything that might jeopardies the integrity of your domain, it is important to ensure that there are no outstanding health issues.  While important, doing this kind of check needn’t be horribly complicated or take a lot of time.  It is important to do every time to be sure that you aren’t replicating problems across your forest as you do domain maintenance.  This is especially critical before schema operations and domain migrations.  Using a few simple Microsoft tools in the Windows Resource Kit, the general health of the domain can be validated and much of the risk associated with the projects can be mitigated.

         Tools & Resources

DCDiag —  Basic Domain Diagnostics
NetDiag — Domain Controller Network Diagnostics
REPLMon — Replication Monitor
NETDom — Domain and Trust Diagnostics

 Procedure Steps

Domain Controller Health Check

Preparatory Work

Update Server Documentation

Gather Inventory of domain controllers from the ADU&C | Domain Controllers node

Locate current documentation from client on AD structure

Locate current documentation from client of site/ core topology

Document name of every AD domain and Sub-domain

Document name and IP address of every Server

Document all trust relationships

Install Support Tools

Server

Log on to the server with Server Administrator privileges

Insert the windows 2000/2003 disk into the CD drive

Navigate to CD:\\tools\Support Tools

Run Setup.exe

Preparatory Work Completed

 

Verify Health of the Domain

Create Log Directories for all Diagnostic Files

Create a Logs Directory at the root of C:\ on the server as C:\Logs

Verify DNS function with NSLOOKUP

Drop to a Command Prompt

At the Command Prompt, key in ‘Nslookup’ <enter>

Resolve each replication partner

Resolve every AD domain and Sub-domain

Fix any failed resolutions

Verify replication function and topology with REPLMON

<ServerName>

Navigate to Start | Programs | Administrative Tools | Support Tools | Replmon

Select the server (<ServerName>) in the Monitored Servers

Select Action | Server | Generate Status Report

When Prompted, specify the file name as c:\Logs\<ServerName>-DDMMYYYY.log

in the Report Options, select all of the reporting options

Click OK

Verify DC health with DCDIAG /verbose on each domain controller

<ServerName>

Drop to a Command Prompt

Key in ‘DCDIAG /s:<ServerName> /v  /c > c:\Logs\ServerName-DCDIAG-DDMMYYYY.log’ <enter>

Wait as the Diagnostic completes

Fix any errors displayed

Run DCDIAG /s:<ServerName> /fix

Repeat the diagnostic

Verify network connectivity health with NETDIAG /verbose

<ServerName>

Drop to a Command Prompt

NETDIAG /v > C:\Logs\<ServerName>-NetDiag-DDMMYYYY.txt

Wait as the diagnostic completes

Fix any errors displayed

Run Netdiag /fix

Run the NETDIAG diagnostic again

Verify all trusts with NETDOM

<ServerName>

Open a  Command Prompt

Type in ‘NetDom query /verify’ <enter>

Verify that all trusts are working and responding to the stored passwords

Fix all errors before continuing

Repeat for each additional Controller

 
As a last point ALWAYS run a backup before completing any form of AD work and if not and it all goes wrong, expect your P45, and rightly so.

What Does 256 CPUs Look Like In Task Manager?

 
An Intel employee posted a screenshot of the Windows task manager showing 256 cores running on Windows Server 2008 R2.

Windows Server 2008 R2 uses the same kernel as Windows 7, which can now accommodate up to 256 processors.

"Sometime between now and when we’re more likely to see machines with this level of parallelism it might be an appropriate area for some UI redesign," he commented. "I don’t know many IT administrators or developers that have a 30" LCD monitor, okay I know one and it isn’t me unfortunately."

 
 

And development will still moan they need more!!
