RTC R2 Connection Error

NaviDev

Hello All,

I am encountering this error whenever I connect to the server.
Any idea on why this error is coming out? And what do I need to do to configure and settle this problem.

Try to check event log for more info (on client and on server). Are you using same versions on both ends? Isn't there some probem that one PC is outside domain? Is the network connection stable?

Hi Kine,

Thanks for the response.

Are you using same versions on both ends?
- No. Both are the same.
Isn't there some problem that one PC is outside domain?
- The client PC is member of the same domain as the server.
Is the network connection stable?
- The connection is pretty good.

The event log showing that the user failed to login, and it is showing this

An account failed to log on.
Subject:
Security ID: NULL SID
Account Name: -
Account Domain: -
Logon ID: 0x0

I have tried to login and connect using the classic client and no problem.
I also tried using SQL Management Server Studio and no problem as well.

I quite lost in this issue.. ](*,)
Please help.

Under which account the NST is running? Is it running on same server as SQL? Are correctly set the SPNs?

Thanks for the reply Kine..

Yeah, SPN's are not configured properly.
