Loss of IP address

Hi,
I am not a network administrator, but I have been tasked by my job to administer the server.  We have a Windows 2003, Small Business server that has 7 laptops and 6 printers.  

One of our users told me that she could not print, so when I looked at it, I noticed that her IP address was gone.  We have been up and running since January 05 and she has had this same IP address since then.  To get her up and running, I changed her IP address - which not an easy task for me.  Now I am worried that there is a software or hardware problem somewhere in the LAN.  192.168.1.130 has disappeared.  Do you have any ideas or how I can trouble shot this, or anything?

I appreciate it.
Tony

In most cases, your server should be setup to give out IP addresses automatically (DHCP). Best way to test this is to remove the ip address you put on her workstation, and just selct the option that says "obtain and IP address automatically". then go to a command line, and type in "ipconfig- release", and then "ipconfig -renew", and then "ipconfig -all". The last command should show you if it received an ip address from your server or not. If not, your server probably isn't running DHCP. IN that case, you'd need to leave her machine as having a static IP...which I just told you to remove.

the benefit of DHCP is that you set it up once, and then all workstations can be dynamically addressed. Probably not a big deal on your small network, but a huge help on big ones. Also, when your workstation recieves an IP address from the server, the server registers the workstation...so it knows you are there.

Just to help avoid confusion - the command is ipconfig /all, ipconfig /release, ipconfig /renew.  Not dashes.

Hmmm.. learn something new every day.... I didn't know "/" could be replaced with "-"  

trispoli, have you rebooted the server lately? How about stop/restart the DHCP server service?

Nope, did not restart the server yet.  I need to do some upgrades and will need to wait until then.  I had to "reserve" the IP addresses to each workstation, because of a digitizer.  Instead of reconfiguring the digitizer every week with a new IP address for a user, it was decided to reserve them.  I understand a reboot may unlock the address, but at this point I have to wait until I can afford to find some down time.

What if I reboot and the IP address is still not working, what do I do then?

Thamks,
Tony

I would suggest assigning a static IP to the workstation in question, if the reboot doesn't work. If it is using a reserved IP in your DHCP scope anyway, there's no reason why you can't just statically assign it at the workstation, in the NIC's TCP settings. Just make sure you set the gateway and DNS server addresses as well.
