We migrated to a new domain but most legacy apps would have been trouble to migrate.. so we have a two way trust. 

Old SQL server with VirtualMachineDB is running on old domain. When I look at the users with access to the DB I find a VMMServer account that has login name as (OldDomain)\ServerName$ 

I'm getting MSSQLSERVER event ID 18456 with the User: (NewDomain)\ServerName$ 

When I attempt to login to the Admin Console I get the generic error ID: 2601     SQL Error Code: 4060

So I would like to know how to create or add this ServerName$ account into SQL or if it's even possible. 

Help me Technet Experts.. you're my only hope!

Hi Sir,

>>When I look at the users with access to the DB I find a VMMServer account that has login name as (OldDomain)\ServerName$

I would suggest you to use VMMTrace to get a tarce log then analysis it :
