Finnish SNA 3.0 NT Client Unable to Connect to SNA Server 2.11

ID: Q173655


The information in this article applies to:
  • Microsoft SNA Server, versions 3.0, 3.0 SP1


SYMPTOMS

When the SNA Windows NT Client, version 3.0, is installed on the Finnish version of Windows NT Workstation, sponsor connections may fail when connecting to SNA Server 2.11. The Windows NT application log on the SNA Server contains many occurrences of an event ID 705, similar to the following:

User: NT AUTHORITY/SYSTEM
Event ID: 705
Source: SNA Base Service
Type: Warning
The description is:
Security Error: Invalid Challenge Response, subcode 002B000AH.
EXPLANATION
Connection request failed due to a security error.
ACTION
Contact your network support personnel.
If a high number of connection attempts are made, the performance of the computer running SNA Server may degrade to such an extent that it appears to stop responding and CPU utilization may be observed at 100 percent.


CAUSE

The problem relates to the localized form of the LocalSystem account. When it is localized in the Finnish version of Windows NT, it appears as "JsrjestelmSTili." Using SNA Server 2.11, an error occurs when it attempts to obtain the LocalSystem account name, which results in SYSTEM being incorrectly returned as the LocalSystem account.


WORKAROUND

To work around this problem:

  • Configure the SNABase service to run under a custom user account that has been granted the advanced user right "Act as part of the Operating System" to allow the normal operation Challenge/Response messages.



STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION

With the fix applied, the LocalSystem account is returned correctly.
