SYMPTOMS
When CONNECT:Direct for Windows NT is configured to operate on a separate
computer running Windows NT than the SNA Server, the host may fail to
successfully submit a job (for example, file transfer, automation
operations, and so forth) to the CONNECT:Direct workstation.
SNA Server version 3.0 and higher may post the following messages in the
Windows NT application Event Log:
Event ID: 705
Source: SNA Base Service
Description: Logon Failed.
Explanation: Connection request failed due to data security.
GetChallengeResponse failed --- Error Code: C0000008H
Event ID: 705
Source: SNA Base Service
Description: Logon Failed.
Explanation: Connection request failed due to data security.
RegisterLogonProcess failure --- Error Code: C0000041H
Event ID: 705
Source: SNA Server
Description: Logon Failed.
Explanation: Connection request failed due to data security. Invalid
Challenge Response --- Error Code: 002B000AH
CAUSE
The CONNECT:Direct service running on the Windows NT workstation is
configured to operate under the Local System Account - therefore running
with NULL credentials. When the application service attempts to establish a
session to SNA Server after receiving the Attach (FMH-5) message from the
host, it fails because of security (lack of credentials).
The Attach message from the host may get processed successfully if the
SNABASE service is operating with appropriate credentials.
RESOLUTION
Configure the CONNECT:Direct service to use a User Account and password
instead of the Local System Account or enable the Guest account on the SNA
Server. The user account must have the right to act as part of the operating
system.
