all dc's 2008 r2

hello,

"we using vmware , machines vm's copy made of storage , presented @ other site. the  cloned/copied vm's started , how dc's , exchange servers site hence reason why dc's\gc's not available because not vm's started in other site"

you cannot built dr site way. if dcs prepared way , connect machines in case of problems dr site, run problems. computers loose secure channel machine passwords not date anymore, users not able logon password may changed before etc.

so if have need dr still have built dc/dns/gc in seprate location/datacenter must assure machine replicates other dcs. in case of problems dc has still inforamtion , users can connect one. , not forget firewalls must open ad http://technet.microsoft.com/en-us/library/dd772723(ws.10).aspx

for exchange dr suggest ask in exchange server forum: http://social.technet.microsoft.com/forums/en-us/category/exchangeserver/

and keep in mind have in dr site 2 dc/dns/gc available.

for worst case scenario please prepare forest recovery http://technet.microsoft.com/en-us/library/cc786327(v=ws.10).aspx
