Cum pot identifica un calculator

Se da un Windows 2003 SE cu Active Directory.
Pe PDC in event log primesc o tona de event loguri ca cele de mai jos si as vrea sa rezolv problema:

Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5723
Date: 12/19/2005
Time: 8:23:36 PM
User: N/A
Computer: PDC
Description:
The session setup from computer 'CN' failed because the security database does not contain a trust account 'CN$' referenced by the specified computer.  

USER ACTION  
If this is the first occurrence of this event for the specified computer and account, this may be a transient issue that doesn't require any action at this time. Otherwise, the following steps may be taken to resolve this problem:  

If 'CN$' is a legitimate machine account for the computer 'CN', then 'CN' should be rejoined to the domain.  

If 'CN$' is a legitimate interdomain trust account, then the trust should be recreated.  

Otherwise, assuming that 'CN$' is not a legitimate account, the following action should be taken on 'CN':  

If 'CN' is a Domain Controller, then the trust associated with 'CN$' should be deleted.  

If 'CN' is not a Domain Controller, it should be disjoined from the domain.


Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5805
Date: 12/19/2005
Time: 8:40:16 PM
User: N/A
Computer: PDC
Description:
The session setup from the computer CN failed to authenticate. The following error occurred:
Access is denied.


Problema este ca nu stiu cum sa identific acest calculator CN,in DNS nu imi apare nici o inregistrare cu acest nume si la fel si cu nslookup (ma rog ,asta zic eu,poate nu am cautat eu cum trebuie).
Ma intereseaza cum pot afla IP-ul respectivului calculator fara a merge de la un calculator la altul bineinteles daca se poate.
Multumesc.

uita-te in logurile serverului

Asa ...si ce caut :)?In afara de ce am scris mai sus,care sunt luate din logurile serverului,nu mai este altceva.

vezi windows/system32/logfiles

Nu este nimic acolo care ar putea sa ma ajute.

NetMon

scuze pentru intarziere,
ma gandesc ca poti captura traficul pe interfata de retea cu NetMon si sa faci o filtrare/cautare a numelui calculatorului respectiv (CN...) in pachetele capturate si sa poti afla adresa de retea a acestuia

nbtstat -a CN
