How to move a DHCP database from Windows Server 2003 to Windows Server 2008


I needed to duplicate my primary DHCP scopes to a secondary DHCP server so I could perform maintenance on my domain controller. Both of my servers are 2003 R2. I came across the following procedure on the Microsoft support site for moving from Server 2003 to 2008 and decided to give it a try.

http://support.microsoft.com/kb/962355

The procedure worked and was quick and easy to implement. I received an error message at the end however upon stopping and restarting the DHCP service I could see all my scopes and reservations on the secondary DHCP server.

Creating WebMarshal Database on SQL Server 2012, Error “Could not find stored procedure’sp_dboption'”


Version 6.9.6.7487  of WebMarshal is not officially supported on Microsoft’s SQL Server 2012 and I wanted to find out if it would work. I installed WebMarshal on to a Windows Server 2012 box for the application server with a backend SQL Server 2012. Following the install procedure for WebMarshal was pretty simple and everything worked great up until the option to create an SQL database. I had previously created my SQL authentication login and password created and I had allowed for SQLServer, SQLBrowser and SQLServer (Port 1433) Inbound on my database server. However I received the error “Could not find stored procedure’sp_dboption'”. The database and log files had been mostly created but the process crashed out.

I proceded to do some research on changes to SQL2012 and came across a few others that had similar problems with other applications. It turns out (suprisingly) that Microsoft had removed the ‘sp_dboption’ from SQL 2012. I continued researching this across Microsoft sites and others until I came across a site by Paul Nezhencev. On this site Paul stated that you can recreate the ‘sp_dboption’ from 2008R2 on the SQL 2012 server and provided an SQL script to do so. The script was great except for a minor error, due to Microsoft having removed (what a surprise) the built-in function ‘databaseproperty’ in favour of ‘databasepropertyex’.

After making the minor modification to the script and running it in the SQL Server Management Studio, I received the message Command(s) completed successfully.

I then went back to my WebMarshal install which I had left at the point of error and told it to create the database again but replace existing as I had no data in the current one. The install proceeded smoothly after this and within minutes I had a fully functioning WebMarshal application.

I have included below the code from Paul with the modifications in case anyone else as the same problem.

SQL Server Does Not Exist or Access Denied


I was unable to see my SQL 2012 Server from my Applications Server and was getting the error “SQL server does not exist or access denied.

I checked in the SQL Server Configuration Manager that TCP/IP was enabled.

I also checked in SQL Management Studio that the SQL Server Agent was running and in the properties of the server, within Connections, that the “Allow remote connections to this server” setting was enabled.

The cause of the issue was the Windows Firewall on the SQL Server. I added the following to the Inbound Rules of the Firewall.
Firewall - SQL Server Ports
The program file paths I used are below.

SQL Browser: %ProgramFiles% (x86)\Microsoft SQL Server\90\Shared\sqlbrowser.exe
SQL Server: %ProgramFiles%\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn\sqlservr.exe

I was now able to select my SQL server from my Application Server.

Setting the Time on Windows Server Using NTP Server.


To configure an external time source on the PDC emulator, execute the following command (pool.ntp.org, used here only as an example):

w32tm /config /manualpeerlist:pool.ntp.org /syncfromflags:MANUAL /update

Always restart the windows time service (w32time) when making any changes:

net stop w32time
net start w32time

To force synchronization with the external time source:

w32tm /resync

To verify the time source you just set:

w32tm /query /source

On Domain Members

To synch  a domain member server or workstation to the domain hierarchy, execute:

w32tm /config /update /syncfromflags:DOMHIER

restart W32Time Services:

net stop w32time
net start w32time

To verify time synchronization  is functioning:

w32tm /query /status

Guide to Setting Up SQL Server 2008 R2


Not being a fulltime DBA I came across a great guide to setting up SQL Server 2008 R2. I used this to help setup my SQL Server 2012.

Windows Server 2012 Storage Spaces: Virtual Disks Detach After Reboot


I built myself a NAS\SAN in my test lab using Windows Server 2012 Storage Spaces, a WD Black 1.5TB disk and a WD Green 2TB disk, Initially this worked well. With the success I decided to upgraded the physical disks to WD Red 3TB disks the process of adding the WD Red disks appeared to go smoothly and I was able to see the new storage from my virtual hosts.

A couple of days later I was preping to migrate the data from my WD Black to the new WD Reds before doing so I rebooted the server. Upon reboot within Server Manger – File and Storage Services – Storage Pools I noticed a yellow warning triangle next to my virtual disks.

My virtual disks had become detached and would not reattach as I was told the disk and name were already in use in the system.

After spending some time attempting to re-add the disks I tried some of the Powershell commands to diagnose the problem.

Get-VirtualDisk

Upon running the Get-VirtualDisk command I noticed that the ISManualAttach values were set to TRUE which did not sound right.

Upon searching for the Set-VirtualDisk parameters (http://technet.microsoft.com/en-us/library/hh848712.aspx) I was able to change this setting by using the following command in PowerShell.

Set-VirtualDisk -FriendlyName yourdiskname -IsManualAttach $False

I checked the settings had changed by running another Get-VirtualDisk and they had.

Upon rebooting and checking in Storage Pools my disks were attached and all my volumes and iSCSI disks were restored.

Where is the “All Users” profile in Windows 7 and Windows Server 2008 R2?


In Windows 7 and Windows Server 2008/R2 the “All Users” profile can now be found as the C:\ProgramData directory.
There can be shortcuts in the C:\Users\All Users directory to the new location, for compatibility reasons, but in most cases you will get an Access Denied message if you attempt to use these.
