In many Enterprise scenarios, primary user for SCVMM is often the person who actually installed SCVMM Server. By default, this person has Administrator User Role in SCVMM and has permission, among other things, to launch SCVMM Admin Console. What happens when Active Directory (AD) account used to install SCVMM is deleted, whether by accident or on purpose? Luckily, any domain account that was in Local Administrators group on server at the time of SCVMM Server installation was automatically added to Administrator User Role as part of install process, and will still have full access to SCVMM. Anyone else will encounter Error 1604 when the Admin Console is launched. At this point there only a couple of options: Find a user whose account was in local admin group on SCVMM Server at the time of install: an SCVMM Administrator User Role member. They’ll be able to log into Admin Console and add your domain account to Administrator User Role so you’ll have full rights. The other option is to uninstall and reinstall SCVMM,” writes Microsoft.
