There is currently an Exchange 2003 server in the enviroment that all mailboxes, ect will be migrated to the new 2010 server.

Please my message again carefully. I have performed everything you had mentioned. this is a single domain that has a total of 8 servers, 4 of which will be decommissioned once the new exchange has been installed. The server can talk, ping, resolve, ect to the domain controller. The account has all of the needed permissions and more. regardsBryan May

As per my research - looks like you need to start from Scratch.. -- Lets see someone as - any other solution. -- Did we used an OS image or Ghost to install OS ? & Is this the first attempt installing exchange in this machine ?Satheshwaran Manoharan | Exchange 2003/2007/2010/2013 | Blog:http://www.careexchange.in | Please mark it as an answer if it really helps you ------------- I do not represent the organisation I work for, all the opinions expressed here are my own.

I have started from "scratch" 3 times, this is a virtual machine, that has all of the requirements. it talks to all DC's. DNS servers, ect. This is a fresh build server, 2k8r2 w/sp1 all patches and hotfixes Bryan May

Check is there any inheritance block on the OU's -- Check is there any inheritance block on the Group policy over the DC's as wellSatheshwaran Manoharan | Exchange 2003/2007/2010/2013 | Blog:http://www.careexchange.in | Please mark it as an answer if it really helps you ------------- I do not represent the organisation I work for, all the opinions expressed here are my own.

yes on both. FYI this is not the first time I have setup Exchange 2010, just have never ran into this issue. and so far, no one has any answers.Bryan May

I understand Bmay -- When you Revert the OS - It reverts only the OS information But the AD information Never gets Reverted it will have the Entries of your OLd hub failed information only -- So Format the Machine or Create a New VM with a Different Name and install it Or you got to remove the Server object from Adsiedit and Format the machine - Reset the Computer account Join the machine into the domain again And start the setup again. --Satheshwaran Manoharan | Exchange 2003/2007/2010/2013 | Blog:http://www.careexchange.in | Please mark it as an answer if it really helps you ------------- I do not represent the organisation I work for, all the opinions expressed here are my own.

Incorrect, when you revert from a snap shot, it takes it back to the original state when you took the snap shot. this is not Hyper-v, this is vmware. Also, I have done both, deleted the vm and started over and reverted from snap shot, and get the same results. Bryan May

Setup Does Numerous Changes in Active Directory When you Revert the Snapshot you mean to say ? Active Directory Objects get deleted and starts from Scratch ==== You can see your server object in the below location in the Active directory even after your "Revert" -- Click Start, point to Programs, point to Windows 2000 Support Tools, point to Tools, and then click ADSI Edit.

Its not Possible-- As because For Example Take a Snapshot of your Exchange2010 Sp1 -- Upgrade to Sp2 -- When your Revert only your machines information and Registry get reverted Not your AD information -- Until you do a Restore of the AD - you cannot acheive that.Satheshwaran Manoharan | Exchange 2003/2007/2010/2013 | Blog:http://www.careexchange.in | Please mark it as an answer if it really helps you ------------- I do not represent the organisation I work for, all the opinions expressed here are my own.
