Event ID 627 Running SNA Services Under WinNT User Account

ID: Q181122

The information in this article applies to:

Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 4.0

SYMPTOMS

If a Windows NT service is written to use the SNA Server APPC, CPIC, LUA, or 3270 EIS API interfaces, and the Windows NT service is not running under an account with administrator privileges, the application will fail to work.

This can be reproduced by trying to start the SNA Server AFTP Server service under a Windows NT user account. This causes the following Windows NT application event to be logged:

Event ID: 627
Source: SNA Server
Description:
Internal message routing error: process id <pid>, mhtype 15, msgtype 0

The equivalent application does run correctly under the same user context when run interactively.

CAUSE

SNA Server was originally designed to restrict Windows NT services to only run in administrative-level accounts (to accommodate requirements on the SNA Server services themselves). However, this restriction is not necessary for services that need access to the SNA Server API interfaces.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0 SP1, 3.0 SP2, and 4.0. This problem was corrected in the latest SNA Server version 4.0 U.S. Service Pack.
