I have a strange issue that I need help with – here are the details:
I recently moved a small business office off of Small Business Server 2000
which was running as a DC, DNS Server, DHCP, and IS 2000. This office has 10
users, so I went the fully manual way. I took a new Windows 2003 R2 server,
built a new DC, and added DNS and DHCP services to it. I changed the Domain
name when I did it as well, because the person who created the initial SBS
2000 domain named it the
same as their registered domain name (which caused issues with the
externally hosted web site,etc). The SBS 2000 domain name was
special-tees.com, and I built the new domain as home.special-tees.com. I
also switched the IP addressing scheme from a 192.168.0.0 group on SBS 2000
to a 10.0.0.0 group on the new domain.
While both domains were running at the same time I went to each workstation,
removed them from the SBS 2000 domain, removed the ISA 2000 Firewall client,
removed them from the old domain and put them in a Workgroup, rebooted,
joined the new domain, renewed their IP addresses with DHCP on the new
Windows 2003 R2 server (10.0.0.0), and configured the workstations Apps, etc
….. I kept both domains running at the same time because I wanted to make
sure I properly removed each workstation for the old domain so no traces of
the old domain would be left behind. Since they are completely different IP
ranges, they were never using the same default gateway address. I did that
for all of the workstations and they are all communicating fine with one
another. I then demoted the old SBS 2000
server and removed the AD, DNS, and DHCP roles that it had.
Here is the issue – they are having intermittent internet connectivity
issues. If I unplug the two Ethernet cables from the ISA 2000 server (which
was acting as their Internet proxy before we migrated to the new Domain),
they have an intermittent internet connection. Sometimes it is really slow,
sometimes it if fine, sometimes they have no connection at all. If there is
no connection I can go to the ISA server, plug the cables back in, and the
Internet connection is back right away at full speed. If I leave it plugged
in, the same thing happens – the internet access degrades and becomes
intermittent. If I unplug them the internet connection comes back immediately
– then the same thing happens again. What is going on? There are two
different IP addressing schemes, none of the systems are pointing to the old
gateway AT ALL on the ISA 2000 server, but for some reason the clients are
occasionally trying to get to the internet via the old ISA server! Am I
missing something here? I even cleared the DNS cache from the workstations
and nothing …
Anyone have any ideas??
