I ran into trouble with DHCP not working also - and I just bypassed it - 4
computers on the network and I assigned IP addresses to each of them. Is
there a problem with doing this?

Is you server antivirus scanning the DHCP database (either through a real
time or a scheduled scan)? If so, exclude it from any AV scan.

I like the idea of uninstalling and reinstalling DHCP. With only four
workstations it won't be much work to reboot each machine, which should
cause them to re-register with the new DHCP database.
You mentioned "you may want to make sure the old database is gone before
you add back the service". Can you tell me how I woudl do this?
Also, and most importantly, do you have any idea why this would happen.
It's the second time that it has happened in about two months. Last time
it happened I did un-install and re-install DHCP and it did resolve the
problem, but I wasn't sure that was what did the trick.
Thanks for your help.

With just a few clients couldn't you just go to Add/Remove Windows
Components and uninstall the dhcp service. Go back and add it back. I
would think it would make up a new database although you may want to
make sure the old database is gone before you add back the service. On
a little SBS network there is not a whole lot in there. Maybe rip
through the Connect to the Internet wizard after you add it back. If
that does not populate the few setting in dhcp you can add those
settings back. You might want to look at your current dhcp options to
add them back later.

I've got an issue that has got me absolutely stumped. I'm hoping
that
someone can offer some advice.
Here's the network structure:
Cable Modem
Linksys wired Router (BEFS81)
Linksys wired 16 port switch
NetGear Wireless Access Point
Windows SBS Standard running on a Dell server with one NIC
3 Desktop Workstations running Windows XP SP2 (wired network
connections)
1 Wireless Notebook PC running Windows XP SP2
The organization is housed in a three story building. The server and
one
PC are on the lower level.
One PC is on the middle level. One PC and the wireless notebook
(along
with the Access Point) are on the top level.
About 3 days ago both machines on the top level of the building (one
desktop & one notebook) stopped connecting with the network. For
many
months up until then all was working fine.
I've tested the wiring (the PC and the Access Point are connected to
seperate data jacks on different sides of the room) and it is fine.
These two machines will not pick up a DHCP address from the server.
The other two machines in the building are working fine.
I've rebooted all the machine multiple times and the ones on the
lower
levels work fine, the ones on the third floor will not get DHCP.
I've
set a static IP address on the third floor desktop PC, and have
turned on
NetBIOS over TCP/IP. With this configuration it is connected to the
network and functioning properly. As soon as I set it back to DHCP
settings it fails to acquire an address.
The other two machines are both picking up DHCP addresses
successfully
(even if I release & renew)
I've already uninstalled and re-installed DHCP and DNS on the server.
This did not change anything.
I've even moved all data wiring to connections on the 16 port switch
so
that the router is only providing internet access, the switch is
providing all network connectivity.
The Windows Firewall is the only firewall on the machines, and it
appears
to be configured properly to allow File & Print sharing.
I'm at a loss. I've got the third floor desktop working with a
Static
IP, but cannot use that solution for the wireless notebook because is
it
used at public hotspots at times so it must be able to pick up a DHCP
address.
Any thoughts, advice, or suggestions would be greatly appreciated.
Thanks,
David
