[Samba] Problem with performance since replacing mainserver

[Richmond Dyes]

Last week I lost my main samba server on my network. It was a domain 
server with 20 users on it and it was working like a champ till it lost 
its main drive.  I was backing up the data and pertinent config files on 
a "backup server". This server was not a backup domain server. I was 
just storing data and these files on it. The files consisted of passwd, 
group, shadow, smb.conf, secrets.tdb smbusers and smbpasswd. I copied 
all these files in the right places in /etc and /etc/samba and then had 
to rebuild my windows groups using net groupmap modify. I used rsync to 
mirror the servers so the permissions and file locations were the same 
as the original server.  When I brought the "backupserver" up as the 
mainserver, I had to have each user rejoin the domain.  But since I have 
done this, the performance has be horrible.  I know I have probably 
messed up some important tdb files.  here is my smb.conf below. Any help 
would be appreciated.
