All We have been told that when we migrate over to Exch2007 and 64 bit OS that we should also migrate all of our DCs over to 64 bit. We were told this is considered a best practice and that Exch 2007 will see big performance improvements if DC are 64 bit. Has anyone heard this??? Comments Thanks Again

Big improvements? I'm not sure, I guess it depends on your environment. See http://technet.microsoft.com/en-us/library/aa996719(EXCHG.80).aspx "The use of 64-bit Active Directory domain controllers increases directory service performance. In previous versions of Exchange, we recommended a 4:1 ratio of Exchange processors to global catalog server processors, assuming that the processors are of similar models and speeds. This recommendation still applies in Exchange 2007." -- Met vriendelijke groet, Jetze Mellema (MS MVP) Lees mijn blog: http://jetzemellema.blogspot.com/ Mijn hobby: http://www.mellema.net/homecomputers How to ask a question: http://support.microsoft.com/?id=555375
You increase your Directory to Exchange processor ration from 4:1 to 8:1, as long as there is enough ram in the 64bit DC's to load the directory into ram. Note however that 64bit DC's are not a requirement, you can keep your current 32bit DC's if they are sufficient. Oliver
Of course 'ration' is actually 'ratio' ;-) Oliver > You increase your Directory to Exchange processor ration from 4:1 to 8:1, > as long as there is enough ram in the 64bit DC's to load the directory > into ram. > > Note however that 64bit DC's are not a requirement, you can keep your > current 32bit DC's if they are sufficient.
If there is not a problem why bother?
