Cannot find the DHCP Server / The parameter is incorrect

Hello all,

I'd like to re-open the problem which has been already subbmited last year,
but without answer to the author Gaylan Ohlhausen (I have not contact to
him).

I am experiencing the following problem with my two 2003 DHCP servers:
They are DCs and have been recently upgraded to SP1. Sometime around the
upgrade time, they no longer allow me to manage the DHCP scopes from the
DHCP
management tool:

When I open a server in the DHCP tool, I get a red X next to the server name
and get the message:



Cannot find the DHCP Server
The DHCP server you specified cannot be located. The DHCP server might be
down, there might be network problems, or the DHCP service might not be
installed. The error was: The parameter is incorrect.
To retry the connection, either press F5, or on the Action menu, click
Refresh.
For more information about troubleshooting a DHCP server, see online Help.

The DHCP server still works - it hands out addresses and such. I am
allowed to get to the server options portion and change settings there -
just
not the scopes.
This is happening to both 2003 DHCP servers - and it appeared at the same
time.

Thank you a lot for info, IT IS VERY HOT for US.
