DOCUMENT:Q185025 11-APR-1999 [exchange] TITLE :XFOR: Dr. Watson on Startup Due to Excess DNS Search Entries PRODUCT :Microsoft Exchange PROD/VER:5.0,5.5 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, versions 5.0, 5.5 ------------------------------------------------------------------------------- SYMPTOMS ======== Upon startup of Exchange, the Internet Mail Service crashes with a Dr. Watson log error message: Application exception occurred: App: MSEXCIMC.dbg (pid=167) When: 4/24/1998 @ 13:28:38.298 Exception number: c0000005 (access violation) CAUSE ===== This is caused by the introduction through RegEdit, or other third-party utility, of additional Domain Name Service (DNS) entries into the TCP/IP configuration under DNS Suffix Search Order. There is a limit of six (6) entries supported under Windows NT 4.0. The Internet Mail Service attempts to parse these entries, and when attempting to store the length of the seventh entry, triggers an access violation. WORKAROUND ========== To work around this problem, do not exceed the supported number of entries. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Exchange Server versions 5.0 and 5.5. ====================================================================== Keywords : Technology : kbExchangeSearch kbExchange500 kbExchange550 kbZNotKeyword2 Version : 5.0,5.5 Issue type : kbprb ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
