Migration to ESXI 5.0 went terribly wrong

Posted on 2011-10-31
Last Modified: 2012-05-12
Here is the situation:

- We had a Windows 2008 server running on a unbuntu server with vmware player
- We had a DC Windows 2008 SBS server running on a unbuntu server with vmware player
- We made copys of the virtuals to external hard drives
- We installed new hardware: 2x Intel core i5, Asus P7Q57-M DO, 16GB DDR3 memory
- We kept de hard drives
- We installed Esxi 5.0 on both servers
- We converted with Vmware VCenter Standalone the 2008 servers with success
- We installed Vmware tools on th servers
- We made a software raid configuration on both servers: we made another virtual disk which serves as RAID1
- Everything seemed to work, untill:

- Our server 2008 suddenly gave a "The username or password is incorrect" error, this hapend after 3 days (this server runs our databases)
- Clients when logging in often get a acces denied when showing their desktops, after reboot it sometimes goes away
- We decided to convert the database server again, after 5 hours we get "The username or password is incorrect"
- Now I get the following error on my SBS 2008 while accessing the active directory: naming information cannot be located the target principal name is incorrect.

Can anyone help?

    Please confirm if the error is when the users are logging on to the domain, if such is the case, remove the machine from the domain and add it back. This might caused because of the secure channel between the domain and the member server is broken.

    Did the MAC addresses change on the servers when you powered them back on under Vspehere 5?  Maybe there were also DHCP entries pointing to the wrong DNS addresses.  Check the DNS listing for accuracy also.

    Check to see that you networks and vswitches are configured for the correct networks from before you migration as well.

    There was a startup script disabled on the database server. If this script was not run, the netlogon services failed to start.
