Solved: Eseutil on running on DPM 2010

As i was protecting an Exchange 2003 (on Windows 2003 R2) from DPM 2010 (on Windows 2008 R2), i needed Exchange 2007 32-bit version of eseutil to be installed on DPM 2010 server.

i had naturally copied the eseutil from Exchange 2003, which did not work so.

So i downloded the Microsoft Exchange Server 2007 Management Tools (32-Bit), installed on a test Windows 2008 Std, 32bit (it had AD installed). i then extracted the eseutil dll and exe and copied to the DPM 2010 server.

This is where i pretty much got the idea that i needed the Exchange 2007 tools.

If you installed DPM 2007 on a Windows Server 2008 operating system, and you are protecting Exchange Server 2003 on a Windows Server 2003 computer, you must install the Exchange Server 2007 version of the eseutil.exe and ese.dll files. You can download this version from the Microsoft Exchange Server 2007 Management Tools (

Installing DPM 2010 Beta in my production.

Installed DPM 2010 beta in a live production environment.
There was very little data on migrating from DPM 2007 SP1 to DPM 2010.

Procedures (#HINT: Read the beta documentation for the basics on the setup. There are also documents on recovery, client protection, SharePoint item level restore etc.).
1. Stopped protection group and retained the protected data.
2. removed the agents (DPM 2007 Sp1) from protection machines.
3. DPm 2010 was installed on a new hardware. Windows 2008 r2 base OS and DPM 2010 Beta. Installation went on without a problem .
4. Installed agents DPM 2010 beta to the servers. They were automatically installed from DPM 2010 Management Console.

Protections Group
Servers i wa protecting in DPM 2007 SP1 were:
Windows 2003 R2 / Windows 2003
SQL Server 2005
SharePoint 2007 SP2
Exchange 2003 Sp2 (Front end and mailbox)
Windows XP SP3 clients.

Moving these servers to protection with DPM 2010 beta, i had this issues.
For a Windows 2008 R2 protected machine i had to install a Windows Server backup before i could successfull add server to a protection group. This was my domain controlller running Windows 2008 R2 which was trying to get the System State back-ed up.

On my exchange 2003 SP2 servers on a Windows 2003 Sp2, i needed a Windows 2003 patch. KB940349 to allow me to backup the exchange storage groups.

Now i am getting issues with Exchange files eseutil not executing. The DPM 2010 is x64 and my exchange 2003 is 32 bit (of course). i loaded the eseutil files to the DPM as requested but seems like it is not working.

The SharePoint 2007 SP2 protection worked like a charm once i had solved the WSS Writer Failures issues with ConfigureSharePoint.exe.

Will write about eseutil once i get it solved.

Mathematics for Automotive Engineering

Cylinder volume = (π/4) x bore2 x stroke

Displacement = (π/4) x bore2 x stroke x number of cylinders

Displacement of overbore = (π/4) x (bore + overbore)2 x stroke x number
of cylinders

Stroke = displacement/( π/4 x bore2 x number of cylinders)

Compression ratio = (cylinder + chamber volume)/chamber volume

Piston speed in inches per minute = 2 stroke in inches x rpm

Horsepower = (rpm x torque)/5252

Bhp loss = (elevation in feet/1000) x 0.03 x (bhp at sea level)

Horsepower = (mean effective pressure x displacement x rpm)/792,000

Torque = (mean effective pressure x displacement)/150.8

Theoretical cubic feet per minute = (rpm x displacement)/3456

Racing carb cfm = 1.1 x (rpm x displacement)/3456

Center of gravity behind front wheels = (rear wheel weight/overall
weight) x wheelbase

Drive wheel torque = flywheel torque x first gera x final drive x 0.85

Wheel thrust = drive wheel torque/rolling radius

g = wheel thrust/weight

rpm after shift = (ratio shift into/ratio shift from) x rpm before shift

mph = (rpm x tire diameter)/(gear ratio x 336)

tire diameter = 2 x (section width x aspect ratio)/2540 + rim diameter

Actual mph = (new tire diameter/old tire diameter) x indicated mph

Blood alcohol concentration = (ounces x %alcohol x 0.075)/weight — (hours x 0.015)
