DOCUMENT:Q178316 20-MAY-2002 [sna] TITLE :SNA 4.0 Backup Server Logs Numerous 670 Events With 3.0 Primary PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:4.0,4.0 SP1 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 4.0, 4.0 SP1 ------------------------------------------------------------------------------- SYMPTOMS ======== After you upgrade an SNA Server backup configuration server to version 4.0 (or 4.0 SP1) in a subdomain containing an SNA Server 3.0 primary configuration server, the 4.0 (or 4.0 SP1) server may continuously copy the Com.cfg file from the primary server even though the configuration file has not changed. Each time the configuration file is copied, the following event is logged in the Windows NT application log: Event ID: 670 Source: SnaBase Description: The primary configuration file was successfully copied to Normally, this event should only be logged on a backup server when the SNA Server configuration file is changed. Over time, this may significantly degrade performance on the SNA Server 4.0 (or 4.0 SP1) backup server, and under heavy client load, may cause the backup server to "beep" whenever the configuration file is copied. CAUSE ===== This problem occurs in a mixed domain with an SNA Server 3.0 primary configuration file. The SNA Server 4.0 (or 4.0 SP1) Snacfg.dll file is not locating the configuration file time properly in the SNA Server 3.0 configuration file, which causes the 4.0 (or 4.0 SP1) backup server to copy the file even though it has not changed. RESOLUTION ========== A supported fix that corrects this problem is now available from Microsoft, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Microsoft SNA Server version 4.0 service pack that contains this fix. To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix.

WORKAROUND ========== Upgrade the primary SNA Server to version 4.0. STATUS ====== Microsoft has confirmed this to be a problem in SNA Server versions 4.0 and 4.0 SP1.
