DFS Namespace - The RPC server is unavailable

A few months ago, we deleted/decommissioned a server name, "DFS-SERVER02" without any issues in our infra. Still, we received notice last week that DFS Namespace "\md.domain.com\data" is not working properly. When the user tries to get that path receives the below error:

Error code: 0x80070043 The network name cannot be found

From the DFS console, I see the below error message:

\md.domain.com\data: The namespace cannot be queried. The RPC server is unavailable.

Well, I ran the following command as my troubleshooting steps:

DFSDiag /TestSites /DFSPath:\\md.domain.com\data /Full

Starting TestSites...
Validating the site associations on every domain controller of the following: DFS-SERVER01
Success: The site associated with the following hostname is consistent on all accessible domain controllers: DFS-SERVER01
Validating the static site association by accessing the registry.
Success: The static site-association of the following host name is consistent with the site-association in Active Directory Domain Services (AD DS): DFS-SERVER01

Validating the site associations on every domain controller of the following: DFS-SERVER02
Error: The format of the specified computer name is invalid.
Validating the static site association by accessing the registry.
Error: The format of the specified computer name is invalid.
Error: The RPC server is unavailable.

Finished TestSites.

DFSUtil.exe /pktinfo

Entry: \md.domain.com\data
ShortEntry: \md.domain.com\data
Expires in 0 seconds
UseCount: 1 Type:0x81 ( REFERRAL_SVC DFS )
  0:[\DFS-SERVER01\DATA] AccessStatus: 0 ( ACTIVE TARGETSET )
  1:[\DFS-SERVER02\DATA] AccessStatus: 0xc00000cc ( TARGETSET )

At this point, it is clear that the server "DFS-SERVER02" is missing, and it was part of the config of the DFSN. As I commented at the start, that server was deleted a few months ago. I reviewed ADSI under "CN=Dfs-Configuration,CN=System,DC=md,DC=domain, DC=com", and I saw some information there, but I cannot see anything related to the membership or ComputerReference.

I appreciate your help on this matter because I do haven't more ideas :)
