DOCUMENT:Q165670 01-MAY-1999 [iis] TITLE :NetScape Navigator Hangs Connecting to Secure IIS Server PRODUCT :Internet Information Server PROD/VER:Winnt:2.0,3.0 OPER/SYS: KEYWORDS:kbtshoot ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server versions 2.0, 3.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you use IIS 2.0 or 3.0, and you secure the site with a 128-bit key from Verisign (or some other legitimate provider), Netscape Navigator version 3.0 appears to hang. CAUSE ===== If the computer hosting the IIS server was originally set with 128-bit security, and then a Service Pack was applied that overwrote the 128-bit Schannel.dll file then Navigator will not connect if it is set to use Secure Sockets Layer (SSL) 3 security. WORKAROUND ========== By default, Navigator installs with SSL 3 security enabled. To connect to the site, either disable SSL 3 security or replace the newer 40-bit Schannel.dll file on the server with the proper 128-bit file. ====================================================================== Keywords : kbtshoot Technology : kbiisSearch kbiis300 kbiis200 Version : Winnt:2.0,3.0 Hardware : ALPHA x86 Issue type : kbprb ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
