Server 2008 64-bit & Exchange 2007 64-bit with 32-bit do

wedge1988

Hi guys,

Does anybody know if you can install exchange 2007 64-bit with server 2008 64-bit on a 32-bit server 2003 domain?

I read somewhere that it doesnt matter if any machine is 64-bit in a 32-bit environment. As long as the drivers are installed on the server. Clients dont recognise 64-bit from 32-bit?

anybody have any ideas that could help?

thanks.

Operating system makes no difference (as long as it is Windows).

Only consideration is that the 32bit domain must be in Windows 2000 native mode or above.

Doesn't matter. I actually have a mix of 32 and 64 bit DC's. From the networking side, it doesn't matter.

Really? Where did you see that? (not that we see much mixed-mode anymore

)

It's true. Your domain has to be in native mode. It's somewhere in the prerequisites. I'll go look later if you actually care to see it in the docs.

Interesting, learn something every day (but like I said, very few people would need to be in mixed mode these days).

Any thoughts as to the why it's required. I could see it being necessary for 64-bit DCs to exist, but for member servers it doesn't make sense - or at least I can't think of a good reason. Any ideas?

Well if you remember, Windows 2000 mixed mode allows for Windows NT4 DC's to be mixed with 2000 DC's, I believe. Exchange 2007 does not play nice with NT4/Exchange 5.5 at all... so this is why you cannot have mixed mode.

Also, you don't HAVE to have 64bit DC's. The only 64bit machine must be the Exchange Server.

Thanks for the reply everbody!

I thought exactly as you speak, it shouldnt matter.

And im sure that server 2008 doesnt even offer mixed mode when you install it.

thanks again! very helpful, it saves me loads of time!

royal

Wedge, that is correct. Windows Server 2008 does not offer any mixed mode options. The minimum functional level is Native Mode.

gorebrush

Wedge, where did you get your signature from...

I like it, and I would like one

Does that mean you cannot install Windows Server 2008 as a domain controller until you raise the functional levels, then?

Lol, i forgot we were talking about Exchange in the OP... I thought you guys were saying to add a 64-bit Windows server to the domain you needed to be in native mode - duh.

lol, dont worry bout it astorrs, its still useful to know!

@ gorebrush - I made it myself! & i watermarked it to stop people stealing it lol.

If any moderators would like to pin a new post ill make with the images, then ill add the entire set i created. I dont have the certs yet to use them all

I'm sure I'd seen a website years ago which let you pick a load of images and it would generate an online sig for you, and it looked exactly like the style you've got, but lord knows where that is now.
