Dumb IP address question
I have a network of about 35 PCs in a Win2003 SBS domain. In addition, I have
two remote offices of four PC's each, also on the domain but via hardware VPN. The main office does have DHCP running on the server, but all the PC's have static IP's, for the reason below. The two remote offices have their own DHCP servers (i.e. the router in each office), but the PC's, again, are all assigned static IP's. In order for users to access their PC's when working from home, I have set each PC's RDP port to something other than 3389, then forwarded that port through the firewall to the static IP address of the PC. Problem: I have one laptop. It also has a static IP address so the user can access it remotely; however, the user took it to one of the remote offices. It could not get an IP address because it is set static, and the users are all set up as Power Users (no local Admin membership). How should I configure this laptop so that it has the correct static IP when in the office by is dynamic when not in the office. Will I need to set it as a DHCP client, but do a MAC reservation on the SBS DHCP server so that it always gets the correct IP address when in the main office? I wish there was a way for Alternate IP Configuration to work in reverse: go to DHCP if the system determines that it is not in the network where its static IP would work. |

Dumb IP address question
Use a reserved rather than static IP?

You are making something very hard that is actually very easy with SBS. Instead of RDP set all the computers in the main office to use DHCP from the SBS server and use Remote Web Workplace to access the computers from home. http://blogs.technet.com/sbs/archive...25/443383.aspx This is a much more secure and easier way to do it, at least for the main office. For the remote offices I'd use a VPN router and have the home users establish a VPN connection to the router then RDP to their desktop. The desktops would still need static (or better reserved IPs) with individual ports for RDP but you could block RDP access from outside the network at the router. -- Kerry Brown MS-MVP - Windows Desktop Experience: Systems Administration http://www.vistahelp.ca/phpBB2/ http://vistahelpca.blogspot.com/ |

Dumb IP address question
as long as you get the routing and registration to DNS right _all_ members
of the domain (local and remote) will be available via RWW. "Kerry Brown" *a*m wrote in message ...

It's tricky to set this up for remote offices unless they have a DC. I have done it and then found it was a better user experience to RDP directly to the remote office rather than RWW to the main office then RDP via RWW (over a VPN) to the remote office. There was too much lag. I guess it all depends on the speed of the links between the main and the remote offices. -- Kerry Brown MS-MVP - Windows Desktop Experience: Systems Administration http://www.vistahelp.ca/phpBB2/ http://vistahelpca.blogspot.com/ |
