DCDIAG error message meaning and way to correct them

Question

Hello All,

I have a Win SBS 2011 server and I am trying to migrate to a Win 2019 Std. server. trying to run dcdiag I get error referencing these errors

Starting test: SysVolCheck

    * You must make sure there are no existing net use connections,

      you can use "net use /d \\QI-FS-02\ipc$" or "net use /d

      \\<machine-name>\<share-name>"

    ......................... QI-FS-02 failed test SysVolCheck

and

Starting test: MachineAccount

    Could not open pipe with [QI-FS-02]:failed with 1219:

    Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.

    Could not get NetBIOSDomainName

    Failed can not test for HOST SPN

    Failed can not test for HOST SPN

and

Starting test: SystemLog

    A warning event occurred. EventID: 0x00009016

        Time Generated: 06/03/2021 19:45:23

        Event String:

        No suitable default server credential exists on this system. This will prevent server applications that expect to make use of the system default credentials from accepting SSL connections. An example of such an application is the directory server. Applications that manage their own credentials, such as the internet information server, are not affected by this.

    A warning event occurred. EventID: 0x00009016

I am wondering what it means and how to correct it.

Any help is appreciated.

Answer 1

Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed

Might try net use * /delete

Please run;

Dcdiag /v /c /d /e /s:%computername% >c:\dcdiag.log
repadmin /showrepl >C:\repl.txt
ipconfig /all > C:\dc1.txt

then put unzipped text files up on OneDrive and share a link.

Answer 2

All looks Ok. Some minor warnings but I don't see any show stoppers. You'll need to migrate FRS to DFSR before hand.

The two prerequisites to introducing the first 2019 domain controller are that domain functional level needs to be 2008 or higher and older sysvol FRS replication needs to have been migrated to DFSR
