Re: Network desintegrating(?)

Hello,

I can't ping Telserv from the clients or Noodserv. The other way around
works, all the clients and Telserv can ping Noodserv.
All programs are working like they should. We have one Foxpro server/client
program running on all the clients where the data is stored on the SBS box.
Network traffic is not heavy. Just a few Office users writing letters.

Is this cable trouble or something with ISA?

Thanks for your patience.

Regards
Dieter

Hello kj,

Thanks for your answer. SuperGumby answered as well.

1 SBS 2003 SP1 server Premium with ISA 2004, 1 Windows 2003 as DC, 15
clients XP Pro SP2

Physically it's
Internet

DSL modem (yes it's a speedtouch)

SBS External
SBS Internal

Internal switch

Lan PC's

I made a reservation for Noodserv in DHCP. I will enter Noodserv as
extra DNS server.
I don't understand the firewall issue. The system was working from
2005 till recently with the firewall client installed. I'm not
questioning you advice, I' m trying to learn something.

The results of the test you performed indicate network connectivity
problems between the two DC with even simple pings failing to TELSERV. On
a simple flat network this usually is a Internal configuration problem
with the server (TELSERV) if not an obvious cabling one. If the windows
2003 firewall is "on" and using the default blocks, these same symptoms
are frequently seen.

Can you successfully ping TELSERV from the XP clients, but not from the
NOODSERV?

Server TELSERV resolved to this IP address 10.10.10.2,
but the address couldn't be reached(pinged), so check the
network.

Hello,

Thanks for your answer. I put the files you asked for as a
attachment. I've seen that before but don't know what to do about
it. I know PDC and BDC are NT 4 terms, TELSERV is the SBS box,
NOODSERV is the extra DC.

Thanks for your time.

Two things. One, you should ony use static IP addresses for servers
and especially domain controllers. OK, three things. After
replication is fixed change the DHCP scope to give clients both DCs
as DNS servers. Disable the windows firewall on NOODServ (probably what
is causing
the connectivity issues). Is this Premium with ISA or just dual nic
SBS standard?

Hello,

1 SBS 2003 SP1 server, 1 Windows 2003 member server as a BDC, 15
clients XP Pro SP2

For some reason I get on the BDC event 13508 errors:

The File Replication Service is having trouble enabling
replication from TELSERV to NOODSERV for c:\windows\sysvol\domain
using the DNS name telserv.bsd.local. FRS will keep retrying.
Following are some of the reasons you would see this warning.


[1] FRS can not correctly resolve the DNS name telserv.bsd.local
from this computer.

[2] FRS is not running on telserv.bsd.local.

[3] The topology information in the Active Directory for this
replica has not yet replicated to all the Domain Controllers.


This event log message will appear once per connection, After the
problem is fixed you will see another event log message indicating
that the connection has been established.

Telserv is the PDC, Noodserv is the BDC. I can ping from the PDC
to the BDC, I can ping all the clients. Everything works fine so
far I can see.
From the BDC I can't ping the PDC. All other connections work oke.

AFAIK dhcp and dns work oke, there are no events in the logs.

On a couple of clients are Userenv errors. Are they related maybe?

The Ipconfig of the PDC and the BDC are attached.

Any help is very welcom, thanks in advance for your time

Dieter

Setting aside the PDC/BDC terminology (for now), it's likely the
Second DC ("BDC") has DNS issues with the First DC ("PDC").

post the output of ipconfig/all from both of your DCs'

Alternativly, run dcdiag /c /e on both and post the complete
results. --
