So, in order to login successfully, you will need to use the built-in Administrator account on Windows XP. If you are using Windows Vista, you will need to enable the administrator account there as well. This account needs to be setup with a password also.
Enable Administrator Account
To enable the administrator account on Windows Vista do the following:
First you’ll need to open a command prompt in administrator mode by right-clicking and choosing “Run as administrator“. Now type the following command:
net user administrator /active:yes
Now if you go to control panel you should see the Administrator account as well:
Click on the Administrator icon and choose to create a password:
Click on the Create password button after which you can try to log into VMware infrastructure web access again, now using these new credentials. It should work.
On Windows XP, the Administrator account is enable by default, so you only will need to setup a password for it.
