Multiple VMs with the same name on one Domain

Recently I copied a Virtual machine that is a member of a domain and wanted to host that machine on the same network, the result was when trying to logon to the machine with a domain account it gives the error:

"The trust relationship between this workstation and the primary domain failed"

The reason for this being that now the domain controller has 2 machines with the same name trying to access it. in this scenario you have 2 solutions:

  1. Logon to the machine as a local user, go into the network settings and change the DNS server of the machine to something other than the Domain IP. This will force the machine to authenticate using cached credentials and you should be able to logon to the machine with the previous domain accounts and work normally
  2. The second solution is to right click on my computer --> Properties --> Change Settings and remove the computer from the domain temporarily and join it to any workgroup. Then restart. Logon to the workstation and re-join the domain. Be careful the dissadvantage to this resolution will be that the DNS on the Domain will update the IP DNS entry of the machine with your machine's IP leaving the other machine inaccessibe (atleast by name)
