Utgard connection opcserver reported an error caused by: org jinterop. dcom. common. JIRuntimeException: Access is denied. [0x800

1. My device
   win10 pro 、kepserver. Prepare to use utgard Compiling opc Client and opcserver Running on the same laptop . therefore dcom You don't need to configure it ？
2. My configuration
   I only in 【 The computer 】 A new user is created under the option ：OpcServer password ：123456. Other security policies 、 The firewall is not set （ Because it can't be set , my 【 Service components 】 Next 【 My computer 】 There is a red arrow on the , Right click No 【 attribute 】, So that's it , The reference is This blog ）

6. The first reference is the technology brother's blog , It's very clear . But I can't keep up , Because of my 【 Component service 】 Under tabs 【 My computer 】 It looks like this , It's different from his .
Finally I saw someone say ,opc server and opc The client runs on the same computer , No configuration required dcom Then I don't know , It should be ok .
Hope to have utgard Connect opc server Big brother of experience , Guide . If you know Kingview as opcserver Better
