Hi

I will try and give as much detail as I can so that yoy may beable to help me.

At the community centre I help out we have about 10 pc's , 1 SBS 2003 server and one adsl router all connected to a 24 port switch.

The router is the default gateway and all the pc's take their IP info from the router(192.168.1.1). All pc's are set to DHCP and the server to a fixed IP. IP range is 192.168.1.2 onwards.

What I have done is that I purcahsed a Freecom networkable hard drive to use for server backups. As the server was the only machine free I though I would test it out on there. This is where it started going wrong :(

I connected the external drive to one of the spare ports on the switch and installed the Freecom software on the server. The software searches for drives and said drive found but it has different network settings. Change your network settings to match YES/NO. I clicked YES by mistake :eek:

What has now happened is that all pc's have an IP of 169.xxxx and none of them have internet acces.

How do I fix this? For now I changed the server IP settings back manually and I will change them naually ont he pcs's but we can't use DHCP anymore as the networked pc's seen to take this 169 IP instead of the 192 one they had before.

i also noticed that in attached devices on the router the server is attached twice. this is thepiconfig/all report

How do I fix this....HELP!
 
I would uninstall anything related to freecom from the server first of all.. back to the square one so to speak. restart the router and try a ipconfig/release, ipconfig/renew on the machines.

p.s why dont you use the server as the dhcp instead of the router?
 
Gaz. I will give it a try.

The reason for not using the server as the dhcp server is because the server was setup to not do dhcp originally by the company who set it up. Since it's in a charity funded community centre there is no IT support anymore as this years budget it was a case of paying for IT support or sports equipment for the kids so the support had to go.

I try and do what I can but I only have limited networking knowledge. Any problems we have had over the last 6 months have been fixed by me posting questions on forums like OCUK and following the advice given by helpful people.
 
first off, set the router to manual IP, somthing like 192.168.1.254 turn DHCP off on the router, then on in the server giving it a range of 192.168.1.100-200 or somthing.
restart all the desktops and they should find the servers DHCP etc
make sure the servers IP settings are correct (gateway 192.168.1.254 etc)
this should sort it all out
