Hi!
We have problem with CU15 on two Exchange 2019 Edge's. We have tried disabling the Windows firewall, making sure the Remote Registry and TCP/IP Netbios Helper service were running, but still this error:
[04.09.2025 10:26:49.0181] [1] Failed [Rule:RemoteRegException] [Message:There was a problem accessing the registry on this computer. This may happen if the Remote Registry service isn't running. It may also indicate a network problem or that the TCP/IP Netbios Helper service isn't running.]

Any suggestions on what to do to resolve this?

MicrosoftHi, the issue is not specific to the Edge role or CU15. You may want to ensure "File and Printer Sharing for Microsoft Networks" is allowed in Windows Firewall over all Networks (Public, Private, etc.); if the issue still remains, run the SetupAssist script
