Went to log into the ESXI 6.5 box today via the web ui and it will not take the username/password. Tried SSH. Will not work. Tried he local console. Same result. It is just like the password has changed... This is the Dell server build. Any suggestions on what to do?
Attached is a link to a possible unofficial solution.
Another way is to reinstall ESXi with the option to keep the VMFS.
You will have to reconfigure the ESXi and manually register the VMs.
