We are in the process of migrating to server 2008R2. We now have 2 2008R2 DC's in mixed domain with the original SBS 2003 server still as operational master. If we run nltest nltest /server:server_name /sc_query:Domain_name on a Windows 7 client and point to the (old) SBS sever we get ERROR_NO_SUCH_DOMAIN, although we have occasionally seen other errors. If we point to one of the new 2008R2 DCs, we get successful completion. Please advise.

Hello, for SBS questions post in SBS forums. I think that you have a problem with your IP configuration. Could you please post the output of this command ipconfig /all > ipconfig.txt on all the servers you mentioned and on teh client computer you used?
