After install WSUS in Virtual Server 2005...Event ID: 2087

The System is Windows Server 2003 which installed in Virtual Server 2005.
The system is very clean before WSUS install, during the installing
procress, there are no errors at all, but when the Server restart, before
login window, it says:"At least one service didn't start up.". Then I check
the Events in Directory Service. The error is:

Event Type: Error
Event Source: NTDS Replication
Event Category: DS RPC Client
Event ID: 2087
Date: 16/08/2005
Time: 15:33:14
User: NT AUTHORITY\ANONYMOUS LOGON
Computer: WIN2003
Description:
Active Directory could not resolve the following DNS host name of the source
domain controller to an IP address. This error prevents additions, deletions
and changes in Active Directory from replicating between one or more domain
controllers in the forest. Security groups, group policy, users and computers
and their passwords will be inconsistent between domain controllers until
this error is resolved, potentially affecting logon authentication and access
to network resources.

Source domain controller:
exc2003
Failing DNS host name:
08e499eb-0f92-48a9-8cc4-cd0921425a36._msdcs.lab.win2003

NOTE: By default, only up to 10 DNS failures are shown for any given 12 hour
period, even if more than 10 failures occur. To log all individual failure
events, set the following diagnostics registry value to 1:

Registry Path:
HKLM\System\CurrentControlSet\Services\NTDS\Diagno stics\22 DS RPC Client

User Action:

1) If the source domain controller is no longer functioning or its
operating system has been reinstalled with a different computer name or
NTDSDSA object GUID, remove the source domain controller's metadata with
ntdsutil.exe, using the steps outlined in MSKB article 216498.

2) Confirm that the source domain controller is running Active directory
and is accessible on the network by typing "net view \\<source DC name>" or
"ping <source DC name>".

3) Verify that the source domain controller is using a valid DNS server for
DNS services, and that the source domain controller's host record and CNAME
record are correctly registered, using the DNS Enhanced version of DCDIAG.EXE
available on http://www.microsoft.com/dns

dcdiag /test:dns

4) Verify that that this destination domain controller is using a valid DNS
server for DNS services, by running the DNS Enhanced version of DCDIAG.EXE
command on the console of the destination domain controller, as follows:

dcdiag /test:dns
