Hi everyone,

I have a windows server 2003 VM running on an ESX server and managing via VMWare Infrastructure Manager. I was removing the AV from the machine, afterwards it needed a restart, i proceeded with the restart and after it came back up it did not allow me to log back in. i get the message:

windows cannot connect to the domain controller, either becuase the domain controller is down or otherwise unavailable, or because your computer account was not found. please try again later.

just a heads up, i am able to log in with my account to other servers without any issues. any help with this would be deeply appreciated. thank you.

Can you login via safemode? Is this a domain controller or a member server?  If member server login via local administrator account and check event logs

unfortunately i don't have the local admin account information, it is a VM, what is strange is that i was able to remote into it before the reboot attempt.

Can you safe boot with networking? If so you may be able to use cached profile.  With Windows 2003 you may be able to use a 3rd party utility such as ERD Commander to reset the local administrator passord and unjoin/rejoin from and to the domain.

suggest u try the following;

1) boot into erd enviornment, erd commander and select the system restore, this will hopefully take u back into the vm enviornment with ur av. if you are able to get past this point, you can log into your vm into the domain, and disbale ur av. reset ur local administrator password. check ur LAN connection settings. check ur vm time settings.

2) are you able to rdp to your windows vm, can u remember if there has been any changes, eg windows updates, etc etc, that could be coming your way. use psexec utility to reset the this vm's local admin password from another pc or server.

depending on how critical this vm is to you and your enviornment, i'd suggest you shut down this vm and take a snapshot, or clone vm as a backup, unless u have vm level backups software, this is to be, jsut safe side to roll back to.

let me know, i have a 30day erd commander cd, that i can upload for you.

Did you change and other settings on the VM?  Machine name for example?

Are the network interfaces ok for the VM?

If you set the virtual network adapter to disconnected it should allow you to log in via cached credentials. At that point you might be better positioned to perform some diagnostics and fix the problem.
