Getting above error while running the credential test for the windows server. I'm doing the Lab 4.3 in SN-DF-No10 ebook.

Anybody could help me with this.

Thanks

Hi @Ajim Shekh,

Check the credentials you have provided in that Credentials table. It may happen due to wrong credentials.

Though I dont have ebook but I do have some experience in discovery.

Check if-

you have valid MID server. Restart it once.
your MID server is able to communicate over port 135 with the server you are trying to discovery. To ensure this you can do Quick Discovery and check the shazzam response. You should see port 135 open.
You might also need few of DCOM ports. Default DCOM ports range depends on your operating system-
- from 1025 to 5000: Windows 2000, Windows XP and Windows Server 2003
- from 49152 to 65535: Windows Server 2008 and later versions, and in Windows Vista and later versions
  
  check https://community.servicenow.com/community?id=community_article&sys_id=4e1c2a21dbd0dbc01dcaf3231f961... for more information.
your credential is specified in this format - Domain\UserName or UserName@example.domain.com. For local account use - .\UserName
IP address you are using is correct. If its discovery of your own machine then IP keeps on changing. In that case get it everytime you run discovery.

If you have these four validated then your credential validation should work.

Hope this helps!
