DOCUMENT:Q153376 08-AUG-2001 [winnt] TITLE :Redial on Link Failure Problems After Upgrade PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.51,4.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.51, 4.0 - Microsoft Windows NT Server versions 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== If you upgrade Microsoft Windows NT 3.51 to Windows NT 4.0, the Redial On Link Failure option may not work properly. CAUSE ===== This behavior was observed in builds through 1345.03 (RC1) and may occur in subsequent builds of Microsoft Windows NT 4.0. After the upgrade from 3.51, the new TAPI API set is not used for modems already defined in Remote Access Service (RAS). Instead, the older style components are left in place and the Modem.inf file is used instead of UNIMODEM. Without using UNIMODEM, the TAPI API set may not monitor the status of the connection properly. RAS may attempt to redial if a connection attempt fails, but may not redial on failure of an established connection. RESOLUTION ========== 1. Click the Start button, point to Settings, and click Control Panel. Double-click the Network icon. 2. Click the Services tab and select Remote Access Service. 3. Click Remove, and then click OK. 4. Restart the computer. 5. Rename the System32\Ras directory to System32\Ras.old. 6. Click the Start button, point to Settings, and click Control Panel. Double-click the Network icon. 7. Click the Services tab, and then click Add. 8. Select Remote Access Service to re-install RAS, and then click OK. 9. Restart the computer. 10. Copy the phonebook files from System32\Ras.old to the System32\Ras directory. 11. Make any other necessary configuration changes to RAS as required. ====================================================================== Keywords : kbnetwork Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400 kbWinNTW400search kbWinNT351search kbWinNT400search kbWinNTW351search kbWinNTW351 kbWinNTSsearch kbWinNTS400search kbWinNTS400 kbWinNTS351 kbWinNTS351search Version : winnt:3.51,4.0 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
