Issue connecting to Matrikon test server

[NeethuES-intel]

Hi All,

Can someone please help setting up Matrikon test server. I am running these on a Windows 10 machine & able to connect to the test serve using Matrikon Explorer. I followed setting up DCOM object as per these instructions - https://www.matrikonopc.com/support/docs/MatrikonOPC-Windows-XP-DCOM-Configuration.pdf Please help.

I get the following "unkown error" if no domain/username/password is used

But get "Access denied. Username and/or password might be wrong." error if I provide my computer's domain/username/password

[emrebekar]

Did you try to create a local user? And second one is, you should be done with the dcom setttings.

@emrebekar I didn't create a local user. Should I do that ? I followed all the steps in the dcom settings link - https://www.matrikonopc.com/support/docs/MatrikonOPC-Windows-XP-DCOM-Configuration.pdf Are there any instructions specific to windows 10 ?

I have problem too. I solve it by change authentication level and minimum session.

[Domenik001]

I got Still the same Issue. I changed the security options, but this was not the Solution. got anyone else the same Issue and can help?

[ping214951]

if you got ACCESS DENIED and in the window viewer have (to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application.). you need to regedit go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole\AppCompat add RequireIntegrityActivationAuthenticationLevel dword 0 RaiseActivationAuthenticationLevel dword 2

Could you please try to define a local user without domain and try connection over this user?

[ping214951]

hi emrebekar,

i only use local user.

This is my experience.

1. In domain field, you need to put some thing in it, if you don't you will get "unknown error".
2. you need to set Local security policy.

      3. In regedit HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole\AppCompat             add   RequireIntegrityActivationAuthenticationLevel dword 0                   RaiseActivationAuthenticationLevel dword 2

      4. restart computer.

Modifying policy no longer has effect after March 14, 2023, need to modify ntlmconnection.js (at node-dcom), override all "protectionLevel" to new Security().PROTECTION_LEVEL_INTEGRITY.

[WarmBoot]

@kevinjhang Hi Kevin, I've tried everything else that has been suggested to overcome the OPC/DA "access denied" error, and your suggestion is one that is more recent and seems to fit the circumstances. Unfortunately, it didn't help, but I'm not sure I applied it correctly. Let me walk through what I did and please let me know if I misunderstood.

I didn't find an "ntlmconnection.js" or an "node-dcom" on my system, so I installed "node-dcom" with "npm install node-dcom". I was really hoping that the problem was a missing package, but alas...

After installing I found two copies of "ntlnconnection.js":

In both of them I found five occurrences of "protection_level"; four of them were something other than "Security().PROTECTION_LEVEL_INTEGRITY" (shaded yellow):

So I changed them to "Security().PROTECTION_LEVEL_INTEGRITY" (shaded blue):

After a system restart, I'm still getting "access denied". Did I apply your suggestion correctly?

Thanks and regards, Jim

Did you try to define domain name as WORKGROUP?

[kevinjhang]

Try this way... Add "--openssl-legacy-provider" parameter with node-red.

Hi emrebekar,

I tried it. Still got the "5 - Access denied. Username and/or password might be wrong" response.

Thanks and regards, Jim

Hi Kevin,

I have it as an environment variable

I also tried it when starting Node-RED

But, still got the "5 - Access denied. Username and/or password might be wrong" response.

Thanks and regards, JIm
