[CentOS] rsync problems on windows

I'm trying to use the CentOS server for windows backups. I want to use
rsync to get the data over there. I downloaded cwrsync, but I'm having
issues getting it to work. I keep getting: "Disconnecting: Timeout,
server not responding." Has anyone seen anything like this? Here is a
transcript:

C:\Documents and Settings\Russ>rsync -vvvvvvv /cygdrive/c/temp/xr
[email protected].
168.1.5:/home/backup-db/test
cmd= machine2.168.1.5 userºckup-db path=/home/backup-db/test
cmd[0]=ssh cmd[1]=-l cmd[2]ºckup-db cmd[3]2.168.1.5 cmd[4]=rsync
cmd[5]=--s
erver cmd[6]=-vvvvvvv cmd[7]=. cmd[8]=/home/backup-db/test
opening connection using ssh -l backup-db 192.168.1.5 rsync --server
-vvvvvvv .
/home/backup-db/test
[email protected]'s password:
Disconnecting: Timeout, server not responding.
_exit_cleanup(code , file=rsync.c, line$2): entered
rsync error: unexplained error (code 255) at rsync.c(242) [sender]
_exit_cleanup(code , file=rsync.c, line$2): about to call exit(255)

And on the server, in secure.log I get:
May 2 18:08:58 localhost sshd[4337]: Accepted password for backup-db
from 192.168.1.36 port 3392 ssh2
May 2 18:08:58 localhost sshd[4337]: pam_unix(sshd:session): session
opened for user backup-db by (uid=0)
May 2 18:08:58 localhost sshd[4339]: fatal: Write failed: Connection
reset by peer
May 2 18:08:58 localhost sshd[4337]: pam_unix(sshd:session): session
closed for user backup-db

I'm using "rsync version 2.6.7 protocol version 29" on the client. I
used the lates (2.6.9 I believe), and downgraded from there, trying to
get it to work.
