I renamed my KMS host server and everything looks updated in DNS; however, my Windows 7 clients still reports the old server name when I run a slmgr.vbs /dlv I have confirmed that my _VLMCS is correct (I only show the one after I manually deleted the old name reference), I have confirmed the DDNS is enabled in DHCP, I have released and renewed IP, I have run slmgr.vbs /ckhc to turn off host caching and then with the /skhc to turn it back on.... but the client still references the old name. Any ideas?

You can verify that the client sees the appropriate DNS record by running nslookup -type=srv _vlmcs._tcp.<your DNS domain>. If that shows the correct record, is it possible that the KMS server address was manually specified with slmgr.vbs -skms? You can use slmgr.vbs -ckms to clear any manually specified DNS name and restore the default functionality of using DNS SRV records to locate a KMS server.

SRV record comes back correct uplon nslookup. The KMS server was not manually specified at any time, but I went ahead and ran the slmgr.vbs with the -ckms switch as suggested and still no change. Running with the /dlv still reports my old server name.

If you try slmgr.vbs -ato to attempt to activate now, does it succeed? slmgr.vbs -dlv might just be showing the KMS server last used to activate.

Hello Tankster, After clearing the cache, try stopping the service and restarting it ( or rebooting), then try a slmgr /ato.Thanks, Darrell Gorter [MSFT] This posting is provided "AS IS" with no warranties, and confers no rights.
