Server virtualisation

We have a number of “critical” servers virtualised and operating on a DR server.

When we wish to add a new server the server cannot log on to the domain.
Our suggested fix is to re-virtualise all servers so they have SID’s which are in synch with the domain controller.

This is an issue which we are attempting to resolve but the advice given is that we have to recreate the whole virtual environment which means we are wasting lots of time, effort and money.
