DHCP Install Problem

Hi,

I'm having a big troble with my DHCP server. on W2k3 server

It stop working.
I tryed jetpack the database, remove and reinstall the DHCP server
among other possible solutions.


The last I did was to uninstall DHCP,
delete the %WINDOWS%\system32\dhcp folder
delete %WINDOWS%\system32\dhcp*.* files
Entered regedit and delete a the key HKEY_CLASSES_ROOT -> CLSID ->
AA5BBsomething

Then I restarted my server and tryed to reinstall it and i got a error
message (my own translation from portuguese) : An error stoped the
installing or removal of the dynamic host configuration protocol(DHCP).
The error was "There is no support for this interface".

I know the problem is not my nick card or my network cables and etc.
because if I mannualy configure a client on the network it goes on
fine.

I really need help on this one. Please advise me on a workaround. I
know I should not have delete the files and this one regitry entry but
I had no idea on waht to do.

Can anyone help me?

I'll be pleased.

P.S. I tryd this solution in the last attempt. Thats what made it
impossible to reinstall DHCP.
I have missed only two things about it. To delete the file
"binlsvc.dll" and to delete this value of the registry
"{524CCE97-A886-11D0-AB86-00C04FC3357A} DHCP"

"If the issue persists, you can refer to the following steps to
manually
reinstall DHCP services to try to resolve the issue:


1. Check your hard disk by chkdsk c: /r /f command.
2. Uninstall the DHCP services from Add/Remove programs.
3. Find the following file and delete them:
dhcpsnap.dll
dhcpmib.dll
dhcpmgmt.msc
dhcpssvc.dll
binlsvc.dll
dhcpctrs.ini
dhcpctrs.h
dhcpssvc.dll
4. Delete %SystemRoot%\System32\dhcp folder.
5. Go to HKLM\SYSTEM\CurrentControlSet\Control\Server Applications
and
delete the following value:
"{524CCE97-A886-11D0-AB86-00C04FC3357A} DHCP"
6. Search for {aa9bb1e0-9fe2-11d0-b257-00c04fc9e292} key in
registry and
delete the key.
7. Restart computer and install DHCP components and check if
problem is
resolved. "
