DOCUMENT:Q298933 06-AUG-2002 [exchange] TITLE :XADM: Exchange Services Won't Start After SP3 Canceled PRODUCT :Microsoft Exchange PROD/VER::5.5 OPER/SYS: KEYWORDS:kbsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- SYMPTOMS ======== When you attempt to load Service Pack 3 (SP3), and you then stop the installation after you receive numerous ".dll in use" error messages, Exchange Server services may not start. When you try to start Microsoft Exchange Directory service, you may receive the following error message: Dsamain.exe -Entry Point Not Found The procedure entry point ?HrRegisterProtocol@@YGJPAVPROTO@@FJJJKHPAXK@Z could not be located in the dynamic link library Netif.dll. CAUSE ===== The issue can occur because the Netif.dll file was not updated due to the cancellation of the SP3 installation. RESOLUTION ========== To resolve this issue, follow these steps: 1. Stop all nonessential services. 2. Repeat the SP3 installation. Each time that you receive the following error message during the installation, write down the .dll file names that appear: Could not open the file named :\Winnt\System32\.dll. It is in use by another application. 3. When you complete the SP3 installation, rename all of the .dll files whose names you wrote down. 4. Search for the renamed files and replace each of them with the appropriate .dll file that is on the SP3 compact disc.
