System/network admin training classes?

[Robert La Ferla]

I am looking for a recommendation for local (MA/NH) training classes  
for system/network administrators.  I'm not sure exactly what we need  
(I have an idea) so I'd like to see what offerings are out there and  
what everyone here has found to be a good value.

Some potential topics:

Configuring VPNs
Configuring routers/firewalls (Netgear/Cisco)
Solaris
RAID
iSCSI
NFS
DHCP
DNS
General TCP/IP troubleshooting

etc...
