Exchangr 2010 Error.

Hi guys,

I'm having this error message, when i'm trying to install Ex2010 SP2 on my lab.

Just to to be clear on my enviorment.

I'm running 2 2008 r2 dc's, the exchange 2010 sp2 that i'm trying to install is the same version i had in my lab before disaster strikes...(btw, i tried to install exchange again using setup /m:recoverserver but it didn't help so i created a new windows 2008 r2 server in my vmware lab).

Anyway, i ran setup from the Exchange sp2 installation, and here is the error i'm getting in the ExchangeSetup log.
