Hi,
 
I successfully installed and executed stunnel without compression and with compression RLE, but with compression ZLIB I receive the following message in the startup:

2005.07.25 08:24:28 LOG3[1408:1976]: Server is down
 
I made download of archive ZLIB1.DLL in the client and in the server, the startup is normal, but after the beginning of the communications the server crash.
 
I use Win2000 Server SP4 in the server and Win2000 Pro in the client.
 
        thanks
