DNS or Routing issue?

D

Dan

I have an SBS2K network w/ one server w/ two NIC's one external and one
internal. For this post I will refer to this doamain as "SBS2K.company.com"
I have added another domain on my network running Win2K3. I will be
migrating all users to the new domain "Win2K3.local.company.com". I have
turned off DHCP on the SBS server and is now being handled by Win2K3 and DNS
is running on both networks.

Right now everything seems fine but, when I am off site and use Windows VPN
to connect to the external NIC of the SBS server I get validated by the SBS
DC. I can ping the internal NIC of SBS. I can ping printers that have
static IP's. I can ping my AIX server which is static and not part of a
domain. But I can't ping or access computers that have DHCP assigned IPs
(assigned by Win2K3 server) nor can I ping or access any of the new Win2K3
servers.

DNS forward Lookup zones for SBS server only has "company.com" on the new
Win2K3 DNS server has both "company.com" and "local.company.com" in the
Forward Lookup Zone.

Is this the problem? Do I just need to add "local.company.com" to the SBS
server? Can that be done on Small Business Server? Will this create a
loop? Or is this a routing issue be cause I can't ping the IP address?

I'm thinking that it may not be DNS because if I ping
win2k3.local.company.com the IP address is resolved but the request times
out.

Example:
c:\ping win2k3.local.company.com

Pinging win2k3.local.company.com [192.168.16.128] with 32 bytes of data:

Request timed out.
Request timed out.
Request timed out.
Request timed out.

Any Ideas? Sorry for being so long but I felt the added detail would better
clarify the situation.

Since the name resolves using ping, this would have to be a routing issue
rather than a DNS issue.
