Well first off, Hello everyone!!

Here is my situation, since I have the most PC knowledge at my company (8 years as a Windows System Admin, until 2 years ago when I went into programming) I’ve been given the task of getting the network to actually work, and I have no clue as what Linux can do. Here are the systems and what functions they are or going to be doing:

• Domain server – None. Just have all PCs in the same workgroup
  
• NetScreen – firewall, VPN, & DHCP for internal systems & VPN clients (just setup & config’d yesterday)
  
• Linux 1 – Samba & CVS (to be setup after Linux 2)
  
• Linux 2 – DNS (not yet, soon if I can figure BIND out) & Backup server for Linux 1
  
• Windows 2k Pro & XP Pro PCs – 40 end-user PCs

As you can see it’s a simple (and unsecured) config. What I want to, that is if it’s possible, is:

• We only have a simple workgroup; I want to setup Samba to act as a domain server. Can this be done?
  
• The workgroup is called example.com, but we have externally hosted web and mail using example.com. Do I need to change the internal domain as not to cause problems with Samba, BIND and the external domain?
  
• Can BIND be setup for dynamic updates, so that Window systems register to it when getting a DHCP IP?
  
• Would I be able to do the above if DHCP was on the same server?
  
• I want to use our ISP's DNS servers, which are Caching DNS servers. Can I just point non-internal requests to them?

I want to say thanks to all in advance for any and all info given.

Thanks
Bio

I can't really help at all, but you should try posting this in the networking forum. Also, you will get more replies if you use a more descriptive thread title

agree - tons of knowledge in the networking/security forums, but this post may be overlooked here. maybe a mod can move it?

welcome to LQ, biomech

itll do whatever you want it to, just be prepared to learn a whole lot of whatever you want to do,

and yes look in the networking furom as a lot of that stuff is covered there
