Well I already saw some posts on this subject, but non of the sollutions seem to work. the error code(s).. ---- 2004/02/19 14:03:00, 0] lib/util_sock.c:read_socket_data(342) read_socket_data: recv failure for 4. Error = Connection reset by peer [2004/02/19 14:06:18, 0] lib/util_sock.c:get_peer_addr(952) getpeername failed. Error was Transport endpoint is not connected [2004/02/19 14:06:18, 0] lib/util_sock.c:write_socket_data(388) write_socket_data: write failure. Error = Connection reset by peer [2004/02/19 14:06:18, 0] lib/util_sock.c:write_socket(413) write_socket: Error writing 4 bytes to socket 16: ERRNO = Connection reset by peer [2004/02/19 14:06:18, 0] lib/util_sock.c:send_smb(605) Error writing 4 bytes to client. -1. (Connection reset by peer) ---- the keepalive=xx and SO_KEERALIVE don't seem to work.. it's not realy bugging us, but if this error occure, no user can log in on that wks. waiting a little, or switching to a other wks works fine.. our WKS are all win2000 sp4 boxes.. anny clou's where these prob's come from ??
