client authentication

We have problem with client authentication from some client.
On server side we use Apache 1.3.24 with mod_ssl 2.8.8.
All client use MS IE 5 or higher and MS Windows 98-2000.
From some client is client authentication without problems, but from some
not.
I think, certificate on client is installed properly.

There is list from ssl logs:
[13/Jun/2002 11:18:18 11431] [info] Requesting connection re-negotiation
[13/Jun/2002 11:18:18 11431] [info] Awaiting re-negotiation handshake
