I think, but I am not certain, that this would occur if the machines were made from the same DVD and license or cloned from each other (again resulting in the same license). Is that what happened?

last weekend we rise the level of a domain, frowm Windows 2003 mixed to native, It was ok, but after rebootint the Sharepoint-SQL environment it does not work, it is having validation errors. &nbsp;Later we found that all the 4 Sharepoint-SQL servers have the same Machine Guid. &nbsp;As I understand, it could not be caused because the rise level... is there any chance that it could be caused because the rise level? &nbsp;Why these machine have the same Gui? &nbsp;(The application worked fine before the rise level and Sharepoint-SQL machines reboot).

last weekend we rise the level of a domain, frowm Windows 2003 mixed to native, It was ok, but after rebootint the Sharepoint-SQL environment it does not work, it is having validation errors.  Later we found that all the 4 Sharepoint-SQL servers have the same Machine Guid.  As I understand, it could not be caused because the rise level... is there any chance that it could be caused because the rise level?  Why these machine have the same Gui?  (The application worked fine before the rise level and Sharepoint-SQL machines reboot).

why could be that 4 virtual servers have the same Machine Gui?

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
