Hello!
We have RDS 2012 deployment with 2 RD Gateways + GD Web Access, 2 RD Connections Brokers in HA and some RD Session Hosts and everything seem to working fine.
But on one RD GW server we have a very strange Audit Failure error in Security Log:
An account failed to log on.
Subject:
Security ID: NULL SID
Account Name: -
Account Domain: -
Logon ID: 0x0
Logon Type: 3
Account For Which Logon Failed:
Security ID: NULL SID
Account Name: ServerName$
Account Domain: DomainName
Failure Information:
Failure Reason: An Error occured during Logon.
Status: 0xC000006D
Sub Status: 0x0
Process Information:
Caller Process ID: 0x0
Caller Process Name: -
Network Information:
Workstation Name: ServerName
Source Network Address: 10.1.1.10
Source Port: 59357
Detailed Authentication Information:
Logon Process:
Authentication Package: NTLM
Transited Services: -
Package Name (NTLM only): -
Key Length: 0
This event is generated when a logon request fails. It is generated on the computer where access was attempted.
The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.
The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).
The Process Information fields indicate which account and process on the system requested the logon.
The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
- Key length indicates the length of the generated session key. This will be 0 if no session key was requested.
where ServerName - Name of problem GW server. So it is connect to itselfthrough network and get error during Logon.
There is no that errors on the other RDGW server, so it think it is very strange.
With Sysinternals TCPView I saw, that connection on that port make a System Process PID 0 with RDS remote name like rds.company.com both in local and remote address.
Any help about that problem?
