[Patch] tcpip32.dll

[Rich Walsh]

Steve Levine has released a patched version of tcpip32.dll that should
prevent the crashes many people have when using the Mozilla apps. The
patched dll and documentation is available from:

http://e-vertise.com/misc/tcpip32-safe.zip

The patch is intended to make this dll multi-thread and SMP safe. It
adds no new code; it simply redirects calls made to unsafe routines
and routes them to safe versions that were already present in the dll.

The patched dll is recommended for those using SMP systems but can be
used with any machine. It is based on the version of tcpip32.dll that
is included with eCS 2.x (2004-05-21 11:15 98,611). It may be com-
patible with earlier versions of this dll but that has not been tested.

Questions or problem reports should be sent to:

The zip contains Steve Levine's explanation of the problem. You'll find it
