Old Windows 2000 DC and new Windows 2008 DC

When transferring the Infrastructure roles from my old Windwos 2000DC  to my new Windows 2008 DC a message tells me that this role should not be transferred to a DC which is also a Global Catalog. Is it a serious message ? Can I do it anyway? SHould I install another DC which is not a GC to transfert the infrastructure role ?

Thank you

Single server dc is not recommended because you need some backup in case you have issues with your main dc.

That being said, if you have a single server dc and you want to use it like that then go ahead and install infrastructure master alongwith gc

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Your goal should also be to try and make every DC a GC,  see bullet 1

In 2008 and 2008 R2 the GC role is even selected by default

Jorge has a great short entry on the IM   http://blogs.dirteam.com/blogs/jorge/archive/2006/07/18/the-infrastructure-master-fsmo-and-the-gc-role.aspx

...also totally agree with Sunny...having at least two DCs is important.

Thanks

You say "having 2 DC is important" for backup and of course I agree with that
But since every DC will also be a GC, how could I separate the infrastructure master from a GC ?

Unless one DC will not be a GC I do not see how to do

Thanks

If every DC is a GC then you don't split out the IM role, the IM role also doesn't really play a role in a single domain environment

Great short blog post by Jorge  http://blogs.dirteam.com/blogs/jorge/archive/2006/07/18/the-infrastructure-master-fsmo-and-the-gc-role.aspx

Thanks

Infrastruture master doesn't require to be on a seperate DC unless all of your DCs aren't GCs and\or if you are running a multi-domain environment
