Hi,

Great thing is that I originally had an AD related question, so I posted my
questions under a diff group. It somehow led to a networking breakdown, and
those guys there have stopped replying, so now I have to type the entire
history to this 'Windows Server Networking' section, all with a hope that I
might get some help !

My DC was working fine until I was trying to set the ScTcbPrivilege for user
Administrator and myself on a DC, with windows server 2003, sp1 installed on
it.

I set the permission in Local Policies for user Administrator with "Act as
part of OS" . Still when i tried to programmatically call -
NTSTATUS ntStatus = LsaRegisterLogonProcess(&lsaString,&lsaHandle,pMode);
I continued to get a bad ntStatus (0xC000041), in other words the privilege
did not seem to be set.

Then I downloaded the Windows Resource Tool kit, and used ntrights to set
the privilege 'ScTcbPrivilege', as originally intended. Still, I was not
getting proper status return programmatically. My system is win 2003 server,
and I tried doing the steps below as user "Administrator":
1. Click Start, and then click Run.
2. In Open box, type rsop.msc, and then click OK.

and get the following Group Policy Error:
"RSoP snap-in was unale to generate the computer or user's data due to
insufficient permissions. Access is denied".

User 'Administrator' does not seem to have access ? Hence I tried to reboot
the machine.

Now the system is behaving wierd..., its unable to see the network, hence AD
is not working, hence I cannot revert the right I had set "Act as part of
operating system"
in Local Policies.

As an outcome of not being able to see the network, I do not see Local Area
Connection settings under control panel -> network connections. Though i can
see the Local Area Connection setting with ipconfig /all. However, the system
cannot see other DC's in the forest..., even Network places thru windows
explorer is not working. Nothing to do with network is not working, the
hardware is ok.

Event log shows the following errors in the order where the first msg below
is the first that occured upon reboot, followed by the rest:
[warning ]: LsaSrv was unable to register its RPC interface over tcp/ip
interface. Event id - 32777
[error]: SAM failed to start the tcp/ip or spx/ipx listening thread. Event
id - 12291
[followed by other errors]: Netlogon error Event ID - 5706, W32Time error
Event ID - 46, IPSec error Event ID - 4292

I tried reset the OS back to the original installation default security
settings by running: "secedit /configure /cfg C:\Windows\repair\secsetup.inf
/db secsetup.sdb /verbose. And rebooted the machine. No luck yet !

Any suggestions on how to get the network going ? thanks.

First, I didn't see this post in either of the AD groups. Second, I'm not of
your intentions to change the default behavior of your OS, so I'm not sure
what you are trying to accomplish by giving the the TCB privledge? I
understand the default Admin account already has that, but I am not definite
about that. See if this helps:

Clearly your errors are based on prgramming errors. Here's one example of
why you are receiving EventID 32777:
http://www.eventid.net/display.asp?eventid=32777&eventno=5647&source=LsaSrv&phase=1

I would highly suggest to first experiment with this on a lab system.
Second, it my benefit you to post this into a more appropriate newsgrouop so
you are able to get more specific help, such as one of the developers
newsgroups (.NET, etc). When you make the post, let them specifically know
your intentions, for they may have a better work around.

I would highly suggest to first experiment with this on a lab system.
It is currently being tested in a forest setup in our lab.

I'm no longer interested in exeperimenting with the privileges, however need

my system back on the network. I just need to know the steps to revert back
(if any) as opposed to re-installing the OS.... Hence I had mentioned the
sequence of steps I had done (in order) to know more about reverting back to
a functional system without worrying about the privilege..

When you used ntrights.exe to set the 'ScTcbPrivilege', what group or user
account did you set it for? You can reverse it as well. In the syntax, you
can use -r to unassign that privledge.

Example to assign for the Everyone group:
ntrights -u Everyone -r ScTcbPrivilege

I also looked up the 32777 error, which I should have done earlier, sorry.
This shows another possible option using the Security Configuration and
Analysis snap-in.
http://www.eventid.net/display.asp?eventid=32777&eventno=5647&source=LsaSrv&phase=1

I would hate to see you re-running setup if something like the above may be
able to reset it. If you do re-run setup, boot up with the cd and select a
repair/upgrade option. It will keep your current users and config, but it
may reset this back to default.

I hope that helps.

Ace
