AFTP Server May Stop Accepting New Conversations (134907)
The information in this article applies to:
- Microsoft SNA Server 2.11, when used with:
- the operating system: Microsoft Windows NT
This article was previously published under Q134907 SYMPTOMS
If the SNA Server 2.11 AFTP Server service is configured to require
conversation security, an AFTP client attempts to log on and provides an
invalid password, and a new valid logon attempt immediately follows, the
AFTP server fails to accept additional client login requests.
CAUSE
This failure occurs due to a timing problem within the SNA Server AFTP
server service.
RESOLUTION
Microsoft has updated the files AFTPAPI.DLL, AFTP.EXE, and AFTPSERV.EXE to
correct this problem.
To work around this problem, stop and start the AFTPD service.
To disable the use of conversation security with the AFTP server service to
prevent the problem:
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
- Run Registry Editor (REGEDT32.EXE).
- From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\SYSTEM\CurrentControlSet\Services\AFTPD\Parameters:
- Set the following configuration parameter:
ConversationSecurity: REG_SZ: NO
