DHCP ROUTER SCOPE DROPS WHEN PC RESTARTS

We have a Windows 2003 server running DHCP with 3 different scopes. Every time we restart our server, scope option 003 router is gone. This totally disappears and we have to add it in again manually each time we reboot. This is the only scope that disappears.  Since this scope is used to locate the default gateway, all the DHCP hosts lose their internet connection.

Has anyone else encountered this, I thought it may have been a scope corruption but there no errors in event viewer to suggest this.  Server 2003 standard SP1 with all the current updates.

Try exporting your dhcp database and looking for the setting:

from the dhcp server-
netsh dhcp dump >C:\dhcp.txt

where c:\dhcp.txt is the full path to the text file to export to

umm... 1st time to learn this kind of strange symptom. i reckon what you speculated was reasonable.  why dont you just simply uninstall DHCP and remove its folder as well, then reinstall the component again?

I had a similar issue after migrating scopes from a 2k server to 2k3.  The DHCP server service would only manually restart.  In services, it to manual and applied the change, rebooted, and set it to automatic again, applied the change and rebooted.  This did the trick, and the dhcp service started normally.  If this isn't the case, try exporting your scopes. Here' the msoft kb:

After doing this, remove and reinstall the dhcp service and reimport your scopes. Bounce the server and verify it can give out releases...
