Migrating a windows 2008 R2 SP2 to a new Windows 2008 R2 SP2 server

Im getting this error "the procedure entry point I_NetpathType could not be located in the dynamic link library NETAPI32.dll"

What do you migrate? Do you just want to add a secondary DC?

dariusg: i mean 2008 r2 to 2008 r2. What i'm trying to do is replace the existing DC with a lower specs computer (this is my test environment) the DC that i wanna take out is gonna be reformatted and put in to Production environment and on that DC i have windows 2008 R2

Then you would just need to add an additional domain controller like the first link.

Make this server a GC.

Run dcdiag to see if you have any errors.

Transfer fsmo roles

You can then demote the other server.

This is what i'm getting at the end of my installation

You need to check your versions make sure they are both Windows 2008 server R2. The error states that the one you are trying to promote is not R2 but instead Windows 2008 server or below.

All of that has been done and checked and all updates has been loaded.  However i am now getting another error that is completely different

It's now saying "Fail to detect if Active Directory Domain Services binaries were installed.  The error was: The remote procedure call failed"

this happens after running windows update then restarting the computer.

Alright so you were able to get pass the above error?

I was not talking about windows updates.

Windows 2008 server and Windows 2008 Server R2 are different versions. The error above was stating your current AD is at R2 so you can not install the older Windows 2008 Server edition as a Domain Controller.

both OS are compatible thats what i'm saying.  So what i did was made sure both are fully updates with all updates and thing, then restart servers and up came this error that i just send.  I now need to get pass that error.

I have never seen this error before. RPC are connection errors or DNS issues. When are you getting this error? Make sure you are pointing to the existing DC for DNS

Is this the new server giving this error?

About the version what I am saying is that the error states that is not Windows updates do not determine versions.

When you get to the command prompt type ver on both servers and post results.

Ver. for both Servers

Is the secondary joined to the domain as a member?

Yes it is.  can I just reformat the SDC give it another name and start from beginning since this is for a test environment?

Yes, you can if you want. Has this server been a DC or is a DC currently?

I would run dcdiag on your current DC to see if any errors come up.

I have reformatted the server, add it to the domain, add Active Directory Role, run dcpromo and it is now a GC DC Type so, so far so good.  Whats my next step to making this the PDC and removing the first PDC?

Run dcdiag check to for any errors

Transfer fsmo roles.

Point the server to itself for DNS.

Run dcdiag again.

If you have DHCP on this server move your scope.

Ok after all that, do i run dcpromo to demote the server? how do i give the new server the name of the demoted one?

Thanks a lot for your help.  I'm now up and running.

Roling out Exchange 2010 next.

Good I am glad I could help out.

you guys are great
