samba - Aug 2004 - Slow logins and groupmaps, Please Help

I have my samba box running as a PDC.  When users
login to the domain, it takes a long time (3-5
minutes).  I gets to the section 'Loading Personel
Settings...' and just sits there for several minutes. 
I've also noticed that the login.bat script only works
for root, and all that does is net use h:
\\samba\homes.  Here's my smb.conf file.  Any help
would be appreciated.

[global]
        netbios name = SAMBA
        workgroup = DOMAIN
        passdb backend  = tdbsam

        # Scripts
        add user script = /usr/sbin/useradd -n -m %u
        delete user script = /usr/sbin/userdel -r %u
        add group script /var/lib/samba/scripts/smbgrpadd.sh %g
        delete group script = /usr/sbin/groupdel %g
        add user to group script = /usr/sbin/usermod
-G %g %u
        add machine script = /usr/sbin/useradd -s
/bin/false -d /dev/null %u

        os level = 33
        preferred master = yes
        domain master = yes
        local master = yes
        security = user
        domain logons = yes
        logon path = \\%L\Profiles\%U
        logon drive = H:
        logon home = \\%L\%U
        logon script = logon.bat
        wins support = yes
        syslog = 5

[netlogon]
        path = /var/lib/samba/netlogon
        read only = yes
        write list = ntadmin

[profiles]
        path = /var/lib/samba/profiles
        read only = no
        create mask = 0600
        directory mask = 0700

[homes]
        valid users = %S
        read only = No
        browseable = No


How do I delete unmapped entries from my groupmap. 
I've managed to delete incorrect entries but I still
have all these unmapped entries that I can seem to
delete.  Here's my groupmappings

[root@samba root]# net groupmap list
System Operators (S-1-5-32-549) -> -1

(S-1-5-21-2915653246-892158047-278579456-513) -> users
Domain Guests
(S-1-5-21-2915653246-892158047-278579456-514) ->
