Unable to relay (problem with outgoing mail)

Hi,

I have two Exchange 2000 native servers, in two site (A
and B, different subnets). Site A is the first site, site
B was added to the AD. Everything worked well untill
suddenly site B Exchange can't send e-mail (receiving is
not a problem). The sender on site B will receive a NDR
stating that

"You do not have permission to send to this recipient.  
#5.7.1 smtp;550 5.7.1 Unable to relay for ......"

And debug event log (SMTP) shows:

Event Type:    Information

followed by NDR notification.


Any idea what the problem can be?


PS:

Also the following problem when trying to reinstall Exchange 2000 SP3:

---------------------------
Microsoft Exchange 2000 Installation Wizard
---------------------------
The component "Microsoft Exchange Messaging and
Collaboration Services" cannot be assigned the
action "Update" because:

 - You must be at least an Exchange Full Administrator at
the Administrative Group level to run update. You must use
an account that has been granted the Exchange Full
Administrator role on the current administrative group, or
a higher-level role, using the Exchange Administrative
Delegation Wizard.

 - Setup is unable to access the Windows 2000 Active
Directory

- Failed to contact the Schema Master server for this
Active Directory forest.

Most likely ur site two has problem with DNS servers.That is what ur
erroe message is telling u.Make sure ur site B does have a dns server
available and also a site B can contact a GC.

How can I check this. SiteB sever has DNS Server installed. How can I see if replication works? When I go to AD Sites and Services, go to Site2 (different subnet) > EXCHANGEB server > NTDS Settings and force a replication withe the EXCHANGEA server I will get the following message:

---------------------------
Replicate Now
---------------------------
One or more of these Active Directory connections are between domain controllers in different sites and cannot be replicated immediately. Active Directory will replicate these connections at the next opportunity.
---------------------------
OK  
---------------------------

If I check the eventlog nothing seems to happen. How can I be sure DNS is working fine and so is the replication to the EXCHANGEA (in Site1)?
