We are in the process of migrating to some online services and encountered an error when we flipped the switch to only allow X from domain computers. All our computers lost their ability to connect. We found that the GUID being reported by the domain computers is different from the GUID being reported by the DCs. Our domain originated on an SBS server way back in SBS 2008 I believe and was migrated to standard AD some time after and has been updated through various windows server versions. The GUID in ADSIedit is the same as the DCs are reporting but the GUID in DNS is different and the endpoints are using that GUID.
Is this still the recommended solution for this issue?
